Koah Spare Spear Shaft Holder

Overview

The Koah Spare Shaft Holder is a speargun-mounted accessory designed to carry an additional finned spear shaft alongside the gun. Its two-piece design secures the shaft at the front and rear, keeping it positioned against the speargun during transport and underwater use.

Shaft retention and design

The rear holder uses a replaceable high-durometer rubber insert that slides into the housing and grips the shaft. Slots on the top and bottom accommodate the shaft's loading fin, preventing the shaft from rotating inside the holder. A separate front clip provides a second retention point, holding the shaft against the speargun. The StarBoard construction is resistant to drying, cracking, and fading.

Mounting and alignment

The holder is designed for installation on the left side of the speargun to avoid interference with the right-side line release. The larger rear component is positioned near the handle, while the front clip mounts farther forward. On Koah Fatback spearguns, the front clip sits behind the third band hole; on roller models, it fits where the gun widens behind the muzzle kicker band hole.

Installation requires drilling 1/8-inch pilot holes for the supplied mounting screws. Both components should initially be secured loosely so they can swivel while the spare shaft is positioned and aligned. Once aligned, the remaining holes can be drilled and the screws tightened. The shaft is then inserted into the rear holder and snapped into the front clip.

Fit considerations

The holder is predrilled to accommodate 5/16-inch and 9/32-inch spear shafts with loading fins. Before mounting, confirm that the speargun provides sufficient space for both components and that the spare shaft can be retained without interfering with the gun's existing hardware.
