The Rob Allen 4 mm Spearfishing Floatline connects your speargun to a surface float. Its buoyant construction keeps the line on the surface to reduce snagging underwater, while the slim 4 mm diameter minimises drag. The line is UV treated for sun resistance and has minimal residual stretch for direct control. Pre-formed loops on both ends make it quick to attach to clips, swivels or float connections.
