Spearfishing float lines are an essential part of the sport. They allow the spearfisher to track their location in the water, mark their spearfishing spot, and attach a float to the end of their line for buoyancy. A float line can be made with a few basic items, and it’s easier than you may think!
Step 1: Gather Materials
The materials needed to make a spearfishing float line are: nylon cord, a buoyant material, scissors, and a swivel snap for connecting your line to the float. The nylon cord should be of a heavy-duty variety that won’t break easily.
The buoyant material can be anything from foam beads to closed-cell foam or cork pieces. Make sure it is lightweight and will not sink.
Step 2: Cut Cord
Cut your nylon cord into two lengths – one should be twice as long as the other. For example, if you want your finished line to be six feet long, cut one length at three feet and the other at six feet.
Step 3: Attach Buoyant Material
Tie one end of the shorter length of cord around your buoyant material. You can use any type of knot that will hold securely – such as a half hitch or figure eight knot – but make sure the knot is tight so it won’t come undone when in use.
Step 4: Tie Cord Together
Tie the two lengths of cord together with an overhand knot or similar knot near one end. This will create an eyelet which will keep your spearfishing float line from becoming tangled.
Step 5: Attach Swivel Snap
Attach your swivel snap to one end of your spearfishing float line by tying it securely with another overhand knot or similar knot.
Step 6: Attach Float Line To Float
Finally, attach your finished spearfishing float line to your desired float by looping it through the D-ring on the bottom of your chosen float.
