The large size is great for belt reels, utility reels, stringers,  and attaching items to floats.

The small size is often used (instead on of a “swivel clip”) to attach your muzzle bungie to your shooting line.  Primarily used on short guns, it makes removing the fish from your spear much faster and easier.  Simply unclip the shooting line, run the fish down your spear, pull the line through your fish and re clip to your muzzle bungie.
