Is a small shock absorber on the shooting line necessary?
Some divers use them, but we feel that the mono line has sufficient stretch in it so you do not need one. The more you put onto a gun the more drag there will be when maneuvering and the more “fittings” that can fail. The only time one is necessary is when using Dynema cord. This is a very strong line, available in less than a 2mm diameter with a break strength of 260 kg. This cord has no stretch and therefore needs a line shock absorber (bungee) just to be able to stretch it onto the line release.
