Hi to you all,ive been checking out some threads and theres some awesome stuff here,great job. Im looking at building my first speargun and am looking at an all rounder about 120 long,2 bands,my own trigger mech and maybe reel,ive been looking at the roller guns and they look great. anyone with some input into a first gun build,please feel free to comment,im looking for some plans but so far have not found any. I dive in southern most point of Australia where our variety of large fish is not to great,the tuna etc in my region are yet to be successfully speared,and in the future would love to have a crack myself,but til they turn up il be freediving and slowly working on my first gun.cheers,be great to chat dive soon. sam. p.s what do you think would be best build for shooting distance and power without using 5 bands etc
