How to Tie Rollergun | Speargun Wishbones with a Handle

 


Here is my quick and easy method of tying dyneema roolergun wishbones with handles. In this How to video, I cover what you need and how to tie up the bridles. These 'soft' handloaders are better than the big hard ones and can tuck away in the rubbers once loaded so they don't obscure your vision when aiming.

Spearfishing Aiming Tips and Techniques

Let's look at some aiming techniques and how and when to use them.

Essentially there are two ways guys take shots. Guys either aim down the barrel or they point and shoot. Often this Point & Shoot is more instinctive and does not rely on ‘aiming’ at all.

From what I have noticed, the guys who use the ‘Point & Shoot’ technique are normally guys who hunt on the reef more. Hunting fast skittish fish in close quarters means that lining up down the barrel is too slow and cumbersome.

While bluewater or open water situations where you chase down fish generally give you loads of time to line up and take the shot. 

Let's look at both techniques and how to master them, as well as the Pro’s and Con’s of both.

Let's look at the most common aiming technique first, and that's aiming down the gun.

This technique is pretty self explanatory as you aim like you would any gun or rifle. Line of sight down the gun at the target.

Most guys aim over the top by first placing the speartip on the target and then adjusting the handle up or down to line up the shot. 

Another way is to come from the side. This can be really effective if the fish is coming in from the right side. By looking down the side of your barrel the height of your shot is easy to adjust or get right. I will often use this technique to determine if a gun is shooting high or low as you there is little mistaking how high you are aiming.

It can also be helpful when on the bottom and aiming at fish approaching you as you dont obscure the target until the moment before pulling the trigger. 

Either way you are lining up the gun like you would a rifle.

The ‘Pro’s’ to this technique is that it is pretty easy to master and if you have the time and an easy target you can make sure of your shot. 

The ‘Con’s” 

Aiming like you would a rifle can take too long. In blue water situations where the target is cruising along. Spanish Mackerel & Wahoo are a good example of this, you can take your time and line up your shot.

But when you are rushed or don't have time, you might land up just squeezing off a shot without being 100% certain of the shot.

When aiming your gun is extended out in front of you. So if the fish is moving erratically or you are in a shoal where your target keeps changing. You landup trying to track your gun and making large cumbersome movements. It is very hard to change target or direction when your gun is extended.

Having your gun out in front of you is an extremely bad habit. It not only limits your manoeuvrability & fluidness in the water. It increases your profile for one, you become in some cases almost twice as long in the water.

You also put an additional barrier between you and the target. Some fish will keep a certain distance from you, whether it is your mask or the end of your gun. Keeping them a whole guns distance further away is not helpful. 

Some fish like wahoo and snapper also don't like to be hunted. These fish read your body language and  having your gun out pointing at a fish is not helpful. I constantly have to remind myself to keep my gun draw in and close to my body.

Another negative to aiming down the barrel is being so focused on the aiming that you forget to brace or lock the elbow in the shot. This is common when lying on the bottom waiting for a fish to come in. 

Having a bent elbow or limp wrist means that when you shoot there is nothing solid holding the gun, and the energy is sent backwards in the gun instead of forwards in the shaft. You lose a massive amount of energy this way. The gun kicking backwards will also affect accuracy as that backwards kick is never perfectly straight back and will affect the way the shaft leaves the gun.

This is why recoil is such a big thing for me. And why guns with recoil are a waste of time.

But even with well set up low recoil rollers you still need to have a sturdy grip and locked elbow, wrist and shoulders.

Another potential issue with aiming down the gun is a lot of your focus is on the gun, so you don't focus on a specific spot on the fish, but rather aim in a general area on the fish. 

Aiming down the gun takes time and it is easy to ‘over aim’ second guess yourself. I think anyone who has dived for any amount of time has experienced this at some time or another. 

Let's look at the ‘Point & Shoot’

The ‘Point & Shoot’ method does not rely on aiming but rather, hand / eye coordination to place the shot. It is the same as taking a stick and quickly pointing it at the target and then without moving, look down the stick you will find that you are pretty much spot on. This shot is particularly good when hunting on the bottom and needing to keep your gun concealed until the very last moment. 

The main Pro’s of the ‘Point & Shoot’ are that you are able to or in some cases forced to keep your gun drawn back and close to your body for longer. And you are forced to make quick decisive decisions and execute the shot with confidence. This means that you are constantly looking for opportunities and weighing up when it is best to take the shot.

In the beginning you might blow a few shots, but as you get better at anticipating situations and executing quick clean shots at the opportune moment you will become far more proficient.

I really believe this is what makes a great spearfisherman. 

The ‘Point & Shoot’ also means that because you are extending out as you take the shot, your muscles in your arm and shoulder are engaged and are better able to take up the recoil of the gun.

A very big Pro for this technique for me is the fact that all your attention is on the fish and the exact point you want to land the shot. You are not distracted by aiming the gun, and focusing on that specific spot on the fish, and when is the best opportunity for that shot. This will make you more lethal in the water.

The cons to the ‘Point & Shoot’ are mainly with handling big clumbersom guns. Even long guns become a problem, and this style is best suited for shorter guns. And this is where shorter lighter rollerguns make all the difference.

Another downside to the ‘Point & Shoot’ is if you miss it is almost impossible to tell if it was you or the gun that messed up the shot. When aiming and you know 100% you were on target and miss, you can be fairly sure there is an issue with the gun. 


So which is better, the ‘Point & Shoot’ or aiming down the barrel? Well actually neither, and I like to use a combination of both techniques depending on the situation. The ‘Point & Shoot’ is more difficult and requires extreme confidence. I have to constantly remind myself to try hunt in this manner. 

Even if it is just going through the motions of keeping the gun drawn in, waiting for the right moment to execute the point and shoot, with a quick aim to check my shot.

A really handy tip I learnt a few years ago is the ‘Poke & Shoot’ This is a technique I have subsequently taught to guys new to the sport as well as those old school guys stuck in their ways. This is a sure fire way to improve your accuracy and grow in confidence. It also helps you move away from relying on aiming down the barrel and transition into a ‘Point & Shoot’ style of shooting. As well as a host of other good things.

How the ‘Poke & Shoot’ technique works is right at the moment when you are about to take the shot, shift your focus onto the exact spot on the fish and project the gun forward imagining that you are pushing or poking the shaft through the fish on that spot.  At the end of this extension, as you would imagine the shaft going through the fish you squeeze off the shot. 

This is not a sharp or fast movement, but rather a controlled movement. I always liken it to a Chameleon about to nab an insect with its tongue. Its tongue comes out smooth and steady, not alarming the prey, and then snap. It shoots forward and nails its meal.  

The ‘Poke & Shoot’ takes the ‘Point & Shoot’ and adds an ‘aiming’ component. Its like aiming without aiming. It is a conscious part of the point motion you focus on right when taking the shot and can also be used in combination with aiming down the barrel.

I often use this when aiming down the barrel to help me to shift focus from the gun on to the exact spot on the fish. 

The ‘Poke & Shoot’ also forces you to fully extend your arm and not make the mistake of having a bent elbow. It also helps those guys who have the bad habit of supporting the gun with the second hand. Either up the barrel or double handing at the grip. Both are unnecessary with rollerguns and only lead to bad habits like having your elbows bent and swimming around with the gun extended.

I also find the whole motion or action helps with committing to the shot. While you are aiming down the barrel at the fish you can pull the trigger at any time and sometimes it can be difficult to know exactly when to pull the trigger. This indecision can lead to you doubting the shot and second guessing yourself.

When you are poking your spear through the specific spot on the fish, you are being very decisive and your shot is at that moment when you are fully extended. Its like the decision of when to shoot is taken away and it is just part of the whole motion. If that makes any sense?

So whether you are an aim down the barrel or a ‘Point & Shoot’ styled diver the ‘Poke & Shoot is a great technique to improve your shots.

I guess this is just small part of an overall way of hunting. Its the full stop at the end of that moment of the hunt. 

So for me I just try remember two things. Keep my gun in and at the right moment poke through the fish and release the shaft. 

Everything else that happens in between will just flow. 

You will start to look for the right moment to extend your gun out. Sometimes it will be a quick point and shoot style shot other times you will line up the shot with time to spare. But finish off the motion by focusing on the spot on the fish you want the shaft to land. 

Push the shaft through that spot as you let the shaft fly. 

Like I have said in this and so many other videos, confidence is key to shooting straight. The Poke and shoot is a technique that can really help you build confidence by helping you commit to your shots and make your shots decisive & functional. My advice is that you get out into a pool or go shoot some fish for the pot. Practice applying the various techniques that apply to you and build your confidence.

The great thing is the Poke n Shoot you can practice in a pool at a target. 

So just a quick recap.

It does not matter if you aim down the gun or shoot from the hip with a point and shoot. Or even a combination of both. Just remember keep your gun in as much as possible. Try anticipate when you are going to shoot and when you do act decisively and focus on the spot you want your shaft to land.

Then whether you are aiming down the gun or not push forward with the gun extending the shaft through the spot you are focusing on and let the shaft fly. This way you will make sure you are holding the gun firmly and have your wrist, elbow and shoulders all engaged. Your shot will then be on exact spot you want and with all the power and accuracy your gun can produce.

8 Spearfishing Tips to keep your Speargun Accurate


Here are 8 Tips to make sure your spearguns are always accurate.


When talking about speargun accuracy and shooting straight, you need to first start with your speargun. 

Is the gun you are using shooting straight?

Now you hear it all the time that this brand is more accurate than that brand. When I hear this I just switch off because this is complete BS and you can make almost any speargun shoot straight with the right setup.

That is unless the gun is completely dysfunctional and badly designed. 


Also make sure you are using the correct gun for the job. Big guns are more difficult to maneuver and will limit your ability to take advantage of the best shots. Leaving you taking flyer shots on opertunities that should have been easy. Likewise a gun with insufficient power and range will leave you frustrated and will only dent your confidence. I do cover a fair bit of this in the previous videos.


If you have a rollergun and are not sure how to set it up I suggest watching this series on Unrolling the roller from the beginning. You will see a link in the top right hand corner.


With that said lets climb right in, here are my 8 Tips to ensure your spearguns are shooting accurately.


No1 - Straight Shafts

You can have everything else right, but if your shaft is bent you are stuffed. If you are battling with accuracy this is the very first thing to check.

Checking your shaft is straight is really simple. The best way is to roll your shaft. You can look down the shaft to see if it is bent. It is difficult to see subtle deflections this way, but if the shaft looks bent just by looking at then you know it is 100% bent and no good.

Rolling the shaft is by far the best and super easy. Take two parallel and level surfaces. The back rests of two chairs works well, but so will two spearguns on a table or any flat surface will also work just fine.
Take some tape and tape up the barb or remove the sliptip.
It is best not to have any shooting line attached, but if you testing a shaft you are using and dont want to cut the line. Use the line to roll the shaft like this.

If the tip wobbles the shaft is bent. You can also hear if the shaft is bent, and it should have smooth even sound. If the shaft is really bent you will see that the shaft will want to stop and always come to rest in the same place. Even a slight wobble will affect your shot.

If an off centered tri-cut affects your shot how much more will a bent shaft?


In this situation it is best to replace the shaft with a new one. But check the new shaft before you put it on the gun. Even better, you check the shaft in the shop before you buy it. Knowing 100% you shaft is straight is 90% of your aiming confidence right there.


No2 - Correct Shaft
Now that you have ensured you are not using a bent shaft, make sure you have the right shaft for the set up you are using.
Make sure the shaft and rubber combination you are using is correct. Often guys use shafts that are too long and thin on rollerguns and this will cause the shaft to whip. This is essentially over powering the shaft and the longer and more flexible the shaft is the easier it flex when coming out the muzzle. This not only causes inaccuracy but the shaft wobble causes drag and slows the shaft down.

The general rule with shafts on rollerguns is the shorter the better.
Again check out the videos on the different setups as a reference.

No3 - Tune your barb

If your shaft is straight and the correct length & diameter. The next thing to check is your barbs. This is alot easier to check in a pool shooting at a target.
Your barbs will affect the height of your shot. The end tip of your barb when flared out will create lift, and will either lift or drop the shaft depending which side of the shaft the barb is on.

 Single barb shafts are most common on the underside of the shaft so if you need to raise your shot you can do so by flaring out the barb.
You only need to flare it out by a few millimeters to lift the shaft by a 5-10cm at range. Likewise if you are shooting too high. Then flattening the barb will drop the shot down.

Many guys battle with double barbs as the top added barb creates drag on top of the shaft making it shoot low.
If this is the case a small flare on the underside of the shaft will lift the shot.

A handy tip is to cut a groove in you dive knife for tweaking your barb. Take a hack saw and cut 3-4mm into a thick strong part of the knife. This way if you are finding your shots are off in the water you can easily adjust your barb right there and then.

I have found this to be invaluable.



No4 - Correct band setup

Now with rollerguns your band setup will not affect your accuracy as much as a conventional gun, they are quiet forgiving. This is mostly because there is very little recoil to deal with.
That said if you have the wrong band setup you will also run into accuracy issues, rollergun or not.

When the guys rollerguns are underpowered they generally don't have accuracy issues other than the shaft dropping at range. But as you start increasing the power you put into the shaft. Then any underlying issues like a slight bend or a shaft that is too long and whippy. You will start to see the accuracy start to become more of an issue. 


The greatest issue is normally with the guys trying to get the most out of their guns. In these cases matching your shaft and making sure it is straight as we have just covered is a good place to start.

But like I have covered in other videos the magic of rollers is not just the accuracy but the way it shoots. 

The way the gun shoots, if it is smooth with low or no recoil, this will help you with your accuracy. What I mean by this is that if you are flinching or having to anticipate the recoil this is going to affect the way you shoot. 

If you need more power and range always opt for a longer gun if you can. Rather than trying to get your 110 or 90 to perform like a bluewater gun. 


When it comes to pretension and accuracy. Because of recoil affecting accuracy, full pretensioning your rubbers is the only way to go. I cover this extensively in the second video of the series.

One of the most asked questions I get is micro bore rubbers and the difference between ‘Reactive’ & ‘Progressive’ rubbers and what is best.

Micro bore rubber in my opinion only makes inserting wishbones difficult and adds little to no value whats so ever. It is not like it magically adds any extra power. The strength of your rubber is directly related to the volume of rubber. Micro bore adds a small amount of volume to the rubber, but in most cases the guys then go down in outer diameter. 


Work out the area of the cross section of rubber. Subtract the internal bore. Compare that between standard bore and micro bore and the difference is nowhere near as substantial as changing the outer diameter. Rubber with a 2.4mm ID is fine.


You land up cutting the rubbers to what is comfortable to load anyway so just stick to the std bore rubber.

Then you have the guys that are about Reactive’ & ‘Progressive’ rubbers. 


My opinion this is just marketing babel. I think the correct term would be high or low modulus rubber, just does not sound as cool. Harder or high modulus rubber can give you more power, but at the expense of recoil. Softer low modulus rubber does not give you as much power, but will provide a smooth accurate shot. Generally the stiffer the rubber is the longer you have to cut the rubbers and the softer it is the shorter you have to go.

Personally I don't like high modulus or hard rubber with rollers.

That said the most important thing to look for in a rubber is low soak off over time. Spearguns are often kept loaded for hours between shots and your rubber should not lose too much load over time. Primeline Latex is probably the best in the market in this regard.

You can have everything right but your rubber setup is the one thing that is going to vary the most from person to person. If you have any doubt about your rubber setups have a look at the previous videos. Start there and tweak your rubbers accordingly. Pretty much everyone who tries the half barrel plus 5cm formula comes back with a thumbs up. So start there.


No5 - Double bridle wishbone

Earlier on in this video I made the comment on guys who say one brand is more accurate than another. For the most part I really do believe this. But when it comes to roller muzzles they are not all created equal.

One of the greatest issues with roller muzzles is the bridle riding up the rails of the muzzle and lifting the back of the shaft as the spear leaves the gun.

Using a double bridled wishbone you can overcome poorly designed muzzles and improve the accuracy and eliminate issues with the back of shaft lifting at the muzzle. 


Check the video in the link on the right hand corner to see how to test your muzzle and rectify the problem.


So I guess you can still make a poor roller accurate after all.



No6 - Shooting line setup

With rollerguns you are generally going 10-20cm shorter on the gun over what you would have used in a conventional speargun. While this has a host of advantages, it does now reduce the length of shooting line and therefore the range with a single wrap and will also affect the guns accuracy at the end of this range.

What happens as the shaft comes to the end of the shooting line, and the slack in the shooting line is taken up it causes the back of the shaft to deflect. This causes the shaft to ‘shotgun’ right at the end of the range.

With short rollerguns this is frustrating because single wrap range is where the gun is still very effective. This means that you have to go double wrap. This double wrap now allows the shaft to hit its target at full single wrap range without being affected by the shooting line taking up the slack behind it. 


You can test this yourself by setting up a target at full single wrap range, and taking a few shots. Then moving the target back one shaft length so that the shaft penetrates almost all the way through the target and compare the accuracy. 


So when guys ask me why I always use double wrap it is not because I want to shoot double wrap distance. Its because I want to be accurate at a practical range around single wrap distance.

There is a down side to double wraps tho, specifically when hunting on the reef. You are now giving the fish those extra few meters of shooting line to run and reef up. So you do need to be conscious to quickly take up the slack shooting line as quick as possible to reduce the risk of getting reefed up.


No7 - Keep all your guns the same

Keeping all your guns the same will reduce the need to adjust from one length gun to another. 

Keep all your grips the same. This will ensure the angle of the grip is not changing, this is very important, especially if you use the point and shoot technique for aiming.

The trigger pull also needs to be consistent regardless of the load on the mechanism. So everytime you pull the trigger regardless of the length or power of the gun, it must be the same.

So for this keep all your grips and mechanisms the same.

Likewise keep the muzzle ends of the gun the same or as close as possible. So when you look down the gun the vision you have is the same.

This also goes for the overhang of the shaft. If the over hang on your different guns vary too much you will have a hard time adjusting from one gun to another. Especially if you aim off the tip of your shaft.

Keeping everything uniform will ensure that you will be able to flip flop between guns, even on the same day without having to adjust or messing with your confidence. 



No8 - Remove all doubt

One of the most important and often not spoken about factors in shooting straight is your confidence. You can have everything dialed in, a great accurate gun in your hand, and if your confidence is low. You will land up second guessing yourself in a situation where the pressure is on. You need to be 100% confident in your gear and your self to make good decisions and take advantage of the best opportunities that come your way. 


This is why pool testing new guns is so important. Getting the gun dialed in and building confidence is the most important thing you can do with a new gun. Better yet, as in the previous point. Keep all your guns the same. This way there is almost no need to go through the learning curve of a completely different gun.

This is actually one of the primary reasons I developed the CDR double rollergun. I have so many clients that are huge Rob Allen fans. But every time we went on a dive trip where they wanted something with a little more vooma than what a std RA could deliver and so got big bluewater guns. 

Almost all the guys battled to adjust to their new bluewater guns with confidence, especially because they were not guns they used on a regular basis. No matter how good they were. 

Now with the CDR they have the same grip, trigger pull and similar view down the barrel so transitioning to a bigger gun is very simple and seamless.

Confidence is everything, if you have been spearfishing for any length of time you will know what it is like when everything is going right and you just can't miss. But you will also know how frustrating it is when you can't seem to hit anything.

In many cases when you start to miss fish on a day its because of a bent shaft or dodgy barb. And if you dont pick up that its your shaft, you will destroy your confidence as you will continue to mess up valuable opportunities.


The best solution to this is to have a complete gun that is 100% perfect to swap out to. Or at very least an extra straight shaft on the boat. 


I try as much as possible to always have 2 of the same or similar gun that I can swap out on any dive. Be it a boat or shore dive. This way if I take a shot and miss, and know it was not because I took a flier. Or if I even slightly suspect there is an issue with the shaft, especially if I have just shot a fish. I swap out to the good gun and never second guess myself.

Here is one last Bonus Tip.

Adapting to Rollerguns

When specifically talking about rollerguns and transitioning from old school conventional guns. Some guys battle to make the adjustment.
I think it is primarily for these two reasons:

No1 - they have one foot in the roller side and leave the other back with their std guns. Rollers and conventional guns shoot completely differently. Conventional guns kind of lob the shaft, with recoil, while rollers feel like they are not doing anything.
Secondly the guys start with longer rollers, they hear about the power you can magically get out a roller. Then get the biggest bad ass setup they can for their next big trip.

Almost without exception the guys who started with small rollers adapt and transition into rollers easier. I think it's for two reasons. For one small rollers really show off a rollers capabilities well. And guys are generally shooting prey that is far less consequential. So they get a bunch of no pressure shots on fish to figure it out. This builds confidence and suraty in the guns.

The guys who go straight to 120 & 130 rollers often land up targeting a ‘quality’ fish and stuff it up. Worse still its on their annual spearfishing getaway with only few opportunities. Straight away there is no confidence, and the gun lands up on the boat in lue if the tried and tested conventional set up.

Then they land up in two camps and never fully transition over, and as long as there is a little doubt. You will never be confident and get on a roll.

So my advice is if you are thinking about getting into rollers or battling with rollers. Get the shortest gun that suits your diving and go shoot a bunch of fish for the pot. Take all your conventional guns, sell, burn, or give them to a mate you dont like. Take them out of the equation completely. Force yourself to take the time to make the adjustment. As long as you keep going back to conventional guns you will have to keep on making adjustments to how you shoot and this is only causes you to second guess yourself when under pressure.


Ok so lets do a quick recap to ensure your gun is 100% accurate.

No1 - Straight Shafts

No2 - Correct Shaft

No3 - Tune your barb

No4 - Correct band setup

No5 - Double bridle wishbone

No6 - Shooting line setup

No7 - Keep all your guns the same

No8 - Remove all doubt


Bonus Tip - go all in on rollers


On a day to day basis the first and last tips are the most important. Always makes sure you shaft is straight, always have another shaft or gun ready to swap over to if you think your shaft is bent.

The 120 Single Rollergun - Unrolling the Roller Spearfishing Series

 


In this spearfishing episode I am going to be dispelling the myth that long rollerguns don't work. As well as why I love my 120 single roller and why I think it's the best rollergun to date made by Rob Allen. 

You hear it all the time out on the internet that long rollers don't work

In theory there should be no reason they would not work. 

One of the reasons small guns work so well, is that proportionately you load more into them. Let me explain. If you are able to load 50-60kg then your loading capacity is the same whether the gun is 90cm or 120cm long. So it is easier to load the right amount of energy into a smaller gun than a longer one. 

All most everything is scalable and the only variable is what you are able to load. And if what you can load is enough, which it probably is. Then there is no reason why longer 120 & 130cm rollerguns won't work. 

In fact the 120 single roller is my all time favourite rollerguns and what I believe to the one best bluewater/reef all rounders available on the market. If I was could only have one gun, this would be it. Making this the best off the shelf gun made at the Rob Allen Dive Factory.

The 110 Single Rollergun Setup

 


In this video I am going to go over my favorite setups for the 110 single rollergun from Rob Allen as well as going over what I think we should be prioritizing when it comes to roller gun setups in general. 

When setting up a speargun of anytype there are three main elements to consider and that is:
Accuracy
Handling
Power
Range

The most important of these elements is accuracy, for obvious reasons. 
You can have all the power in the world, but if you can hit the spot its pointless. Accuracy is the golden key to any magic setup and has to be your first priority. 
However most guys focus on ‘power & range’ when setting up their guns, and just assume that because it is a roller it will be accurate.

Another problem with having ‘power & range’ as your focus when setting up guns is not paying attention to how the gun handles in the water. 

Recoil, weight & maneuverability all affect how the gun feels. This might seem insignificant to some, but how the gun handels affects accuracy. Recoil affects the guns accuracy, and the way the gun handles will affect your accuracy.

It is the way you and the gun interact. Heavy or cumbersome guns, hinder agility. Agility affects your reaction time. 
The faster you can take advantage of a situation, the greater options and opportunities you have of a good shot. 
When things are smooth and predictable, it is easy to be comfortable and find confidence in the gear. 
 Confidence is another key element to accuracy, this is the accuracy that you as a diver develop with experience, enabling those quick instinctive lethal shots. 

So when you have accuracy as your starting point when deciding on a setup. You need to also prioritise how the gun feels and handles, over how much power and range it will have. 
Work with in the power and range a good setup can give you. And not the other way round.

Using this philosophy on gun set ups lets take a look at the 110

The 900 Single Rollergun - Unrolling The Roller Speargun

 


In this spearfishing workshop episode, I cover my favourite single rollergun setups, starting with the 900cm speargun. This is the setup that I have found to have a good balance between power, accuracy and the overall feel of the gun. 

Possibly one of the greatest factors that determine the setup I use is buoyancy. A 900 roller first off needs to have enough buoyancy to float the roller gun with the shaft out. Must remember that all the components on a gun remain the same, but the shorter the gun, the less volume /buoyancy you have to play with.

A carbon barrel in this case is essential, and also adds to counter the weight of the shaft. Even then the carbon barrel will only be buoyant enough for a 1.3m 6.6mm shaft. But if you don't mind a slightly heavier muzzle then a 7mm works really well too. 

Being a short gun makes the 900 easy to load. So I prefer to hand load 14mm bands which have more than enough power to drive the 6.6mm & 7mm shafts.
Lengths will depend on your rubber. 45cm (400% when loaded)  is as short as I would go if you can load it. 50cm is a good length to start with. 

Speargun Setup:
Gun: 900 Carbon Rob Allen Speargun or similar buoyancy
Rubbers: 14mm @ 45cm -50 cm
Pretension: Maximum
Spear: 1.3m 6.6mm shaft – double wrap 1.8mm Dyneema

Cheers
