The Rob Allen 7 mm double notch speargun shaft is a replacement spear for guns with Euro-style trigger mechanisms. It is built from oil-quenched carbon alloy spring steel tempered to 2100 MPa for high tensile strength and good straightness retention, and it uses a tri-cut tip designed for penetration.

How to choose and care
Choose a shaft length that matches your speargun: the shaft must be long enough to sit properly in the mechanism and clear the muzzle. Check your gun’s manual or contact us if you are unsure. Rinse the shaft in fresh water after each dive, dry it and wipe it lightly to protect the coating, and check it for bends before use.
