Comments about Aqua 8" to 7 FT Sea Spring Coil Shock-Line for Spear-Gun:

I bought three of these short coils for cameras, lights, regs, speargun, etc., and they work at least as well as the retractables, but cheaper. You will probably need at least one extra clip for the split-rings on the ends, depending on what your attachment needs are.

I bought it for my medium Sten but is still too short and too rigid then when you fired the gun the shaft loose a lot of energy in the travel. I recommend the use of standard lines.

I recently bought this product because of a speargun malfunction. It works great for open water but down in the stumps it is not as effective. Wound recommend having is case of malfunction in your cable holder on you speargun.
