Rob Allen Euro Speargun Shaft

Overview

The Rob Allen Euro Notched Speargun Shaft is a spring-steel flopper shaft for spearguns using compatible Euro-style trigger mechanisms. It combines a Euro sear profile with a tri-cut hunting tip and bottom-mounted flopper.

Construction and loading

The carbon-alloy spring steel is oil-quenched and tempered to provide high strength while retaining the resilience needed to resist permanent bending under normal shaft loading. Each shaft is straightened and quality checked before machining.

Polished loading notches provide contact points for compatible wishbones. Their smooth contact surfaces are intended to reduce wear where the wishbone engages the shaft during loading.

Tip and retention

The tri-cut point forms the penetrating end of the shaft, while the bottom-mounted flopper provides retention after the shaft passes through the fish.

Fit and shaft selection

The crescent-style sear is intended for compatible Euro trigger mechanisms. The notched shaft configuration can be used with suitable open- or closed-muzzle spearguns when the trigger mechanism, shaft diameter, and overall shaft length are appropriate for the gun.

Rob Allen normally equips its spearguns with shafts approximately 40 cm longer than the nominal gun length. A compatible shaft one size shorter or longer may also be used on Rob Allen spearguns, but changing shaft length can alter the gun's aiming reference.
