The Rob Allen 7mm Double Notch Shaft is extremely strong yet still flexible. Engineered from ultra-tough oil quenched carbon alloy spring steel, the shafts tempered to 2100Mpa, increasing the toughness of iron-based alloy.
This shaft is a good round choice for medium to larger fish and will easily penetrate any medium to large-bodied fish from a long-range, on the right gun, of course. The speargun will need to be the correct length with the correct rubbers to give the spear that power.
The Tri-cut tip is super sharp, therefore ensuring excellent fish penetration. Coming with a spring steel flopper will allow you to hold on to the fish without coming off the spear while fighting it.
The double notch has 270 degree polished wishbone notches, and polished line holes ensure minimum wear while allowing you to pull back two rubbers onto their own notches, giving you even more power if needed for the larger fish.
Every spear length fits a different speargun length.
