It is important to attach a float line to your gun and/or your break-away spear, flashlights, etc. Having a float line means that you can retrieve your speargun from the surface, in case you drop it. It also allows you to shoot larger fish and let it “run” until you get to the surface. Float lines are can be made from a variety of materials and come in many different colors.
A fish stringer is another useful accessory to have. It is essentially a line of rope or chain that allows the spearos to string their fish so they can be immersed and kept alive in the water. A springer is usually made of a line of rope or wire with a metal stringing needle at one end. The other end normally comes with a removable wire ring, used to secure the stringer. The hunter needs to thread the needle through the fish’s gill and out through its mouth, or better, through the upper and lower lips which allows the fish to breathe freely through its gills.
