This makes spearfishing easy after you shoot just load shaft and shoot again

great to use underwater, faster to reload, and don't have to worry about the rope.

Makes reloading quick - but it can tangle like a phone cord, but much better than the old line method.

I got hung with a standard cord while a cobia was swiming around in circles. I bought this and have shot lots of fish with it. It will pull back, reverse coil on you, and shorten shots but the saftey of not being tangled with a standard line and the quick reloads without having to fittle around with standard line, it is worth. Works great on flounder, sheephead, cobia, black drum, amberjack, and spadefish. After the dive, if the line has back coiled, I fix it once on the surface and enjoy lots of uninterrupted shots on the bottom. Get the longest line available.

This is definately not to be used as a shockcord. It might stretch to the length the description says it does if you are using it on a bazooka. I bought a 20' one for my 32 inch speargun and its max effective range with this is around 8-10 feet. I now use it as a lanyard from my weightbelt to my speargun and it works great.
