Installation Jigs for Trigger Mechanisms are an extremely critical piece of equipment for the speargun builder. These jigs allow you to drill and build your speargun with piece of mind. Also you don’t risk making a mistake or having to re-drill the holes you make.
Additionally, the jig helps you to determine the exact spot to drill your mounting holes or cut a line release slot.
On top of that it helps you determine the exact location of your line release pivot pin.
