Keep your fishing gear organized while you continue the hunt with a LABRAX fish holder With a fish holder it becomes incredibly easy to keep track of your catch while you continue the hunt. The fish holder is incredibly easy to use, and if you have a spearfishing fleet, it really makes it easy and convenient for yourself. How to use a fish holder Once you have caught your fish and removed it from your spear, use the "old" hole in the fish to run the small spear with the string through the fish. This way you will get the fish on your fish holder and you can now keep track of your catch while you continue your hunt.
