I am looking into buying a new speargun... so i came across a gun .... beuchat canon... it comes with double band and stainless stee trigger mech and 30 mm tube... but i dont think it has a spear guide... so i was wondering if anyone knows about this gun... how accurate is it? I do know its durable and got gd penetration for my fish game... but im do conserned about accuracy for the lack of spear guide
