Overview
This Diamond floatline is a 60-foot length of yellow polypropylene braided line built for spearfishing, connecting a diver or speargun to a surface float or buoy.
The category tag on this listing reads braided fishing line, but the title and materials point to a spearfishing floatline rather than a rod-and-reel line, since polypropylene floats, exactly what a line meant to stay on the surface and mark a diver's position needs to do. At 0.64 pounds for 60 feet it is a working-length line rather than a short accessory piece.
- 60-foot (720-inch) length
- Polypropylene construction floats
- Hi-vis yellow
- 0.64 pounds
Who it's for
Spearfishers who need a surface floatline to tether a gun or diver to a float or buoy. Not a fit for anglers shopping for a casting or trolling line, since polypropylene does not behave like monofilament or braid made for rod and reel.
Pros and cons
- Polypropylene construction floats on the surface
- High-visibility yellow color
- 60-foot length gives working range
- Not built for casting or reel use despite the braided-line category tag
- Single color and length option shown
Performance notes
Polypropylene floats rather than sinks, keeping the line on the surface and visible instead of dragging or snagging below a diver. High-visibility yellow adds to that, making the line easier to spot and track from a boat or the surface.
