Koah Euro Open Track Speargun

Overview

The Koah Euro Open Track is a band-powered Euro speargun for general freedive spearfishing and reef hunting. It combines a laminated teak stock with an open shaft track and Koah’s reverse-trigger Euro handle system.

Trigger and track design

The Brute reverse trigger arrangement increases usable band stretch within the gun’s nominal length. The open track keeps the shaft directly accessible during loading, while relieved channels near the forward section reduce material in the sight line when aligning the shaft with a target.

Balance and configuration

Solid lead ballast is incorporated into the stock, while a variable ballast pocket at the muzzle allows the forward balance to be adjusted. The standard shaft setup can be changed to a heavier 5/16-inch shaft, and the gun provides room for an optional third band when a different power configuration is required.

Choosing a length

Gun length affects loading reach, underwater tracking, and maneuverability. The appropriate configuration depends on the diver’s loading reach, intended target species, and the amount of working space typical of the hunting environment.
