Ciao Tommaso. Io non ho mai usato it roller. Mi sono trovato bene con questo fucile, Pero ho cambiato l Asta ha Una di 6.5 mm. Non so se questo fa la differenza. Grazie
Thank you Youssef Hassan. If you leave the gun as sold without any modifications it is very well balanced. I changed a bit the set up with a 6.5 mm shaft and mounted the GoPro mount half way along the shaft. So I needed to add about 20 grams of weight at the tip.
@@davidsammutfishing6137 i see . I ordered it with a 7 mm while it came with a 7.5 mm. It floats terribly from the tip it even sinks perfectly vertically and stands up on its butt at the bottom!!!
Hello @koldman. The gun is slightly modified using a longer thinner shaft that comes with the original. The weight is balanced by the camera and it's mount which is roughly at the middle of the gun.
@@davidsammutfishing6137 I haven't had a chance to test it properly because of the buoyancy issue. Overall I am very pleased with the quality and the design. I am planning to change the shaft to 7mm though
@@rjfspearfishingtrip1964 I aim on the tip of the speargun, so I prefer a long shaft. Mine is 150 cm. The standard shaft of the Hero 105 is a 7 mm X 130 cm long shaft.
My spear shaft is 6.5 mm. It shoots very silently and fast. The negative is that if you are after large fish it bends easier and even if shot inside the rocks. If you use a 6.5 mm be careful to use a shark fin type and a good brand.
