Rob Allen Speargun spear 7mm DN

7 mm diameter
Tri-cut tip
Double notch
Fits all Euro gun mechanisms
7mm Diameter: Designed to penetrate large deep bodied fish at longer range, 7mm shafts retain much of the kinetic energy at the edge of their range. 
Rob Allen Impact Spears are designed to fit all Euro gun mechanisms. Engineered from ultra-tough oil-quenched Carbon alloy spring steel that are tempered to 2100Mpa. Tri-cut tips ensure excellent penetration while the rock-tip is designed for close quarter reef fish hunting.
270 degree polished wishbone notches and polished line holes (available in both single & double notch configurations) ensure minimum wear. Each spear is mechanically decoiled from the heat treated bulk roll and hand straightened and quality checked before machining. Quatro phase coating ensures corrosion protection four to five times better than conventional electro-galvanising.
