Spearfishing fish stringers are clipped onto your float and used to secure your fish. AVOID attaching the stringer to your belt as this creates drag and also could deploy in rocks or kelp delaying your return to the surface.
They are very simple but effective, a short metal bar attached to mono line. The pointed end of the bar should be pushed either through the eyes of the fish or can simply be threaded through the gills of smaller fish.
We stock stringers of varying size bar depending on the size of fish captured, and some with marine grade clips and others with plastic. All will do the job in UK waters.
