Manny Sub stiff dyneema sold by the foot for use as shooting line. No need to buy an entire roll. This line can either be crimped or tied with a knot to connect your spear shaft to a muzzle bungee or reel line. Unlike monofilament, dyneema won’t train or get nicked up on the reef. Use the 1.4mm (770 pound breaking strain) for minimal drag when targeting small to medium fish. The 1.7mm (946 pound breaking strain) is ideal for more powerful guns and shooting larger fish.
