I have just released the newest version of my double roller the CDR3L. This new 'lighter' version is the same as the CDR3 but with smaller lighter bearings. This reduces the weight of the muzzle by 35g which significantly affects the buoyancy on spearguns using std Rob Allen railed barrels. Giving the same affect of either increasing the barrel length by 5cm or reducing a 7.5mm steel shaft by 10cm.
This improvement in buoyancy almost eliminates the need for cuttlefish barrels on the longer 120 & 130cm guns. This means that you have a well balanced speargun that is as sleek and manoeuvrable as a std Rob Allen 'pipe' gun, but with all the benefits of a powerful double roller.
With the CDR3L's weight similar to that of the std Rob Allen single roller, shorter guns like the 100cm & 110cm are now way more practical options than before. So now you can easily hand load guns from 100cm up to130cm shooting 7.5mm shafts without sacrificing any performance.

To achieve this buoyancy improvement The size and weight of the bearing needed to be reduced without sacrificing performance, and durability in harsh spearfishing conditions. The solution is the new ultra light & strong hybrid ceramic bearings, with stainless steel inner and outer races. The Stainless steel inner and outer race ensure the durability against impact and deforming under high loads.
