Here are a few. I can post more later but I'm about to go spearfishing right now. Sorry to sound like an ass, just saying it works great with just a single knot. Maybe if you use a thicker band tying line I could see where you might need an extra knot, but for the thin mako line it works great. You can also use line called Dacron that you buy from fishing stores that comes in a spool and would probably be less money then buying it from a spearfishing store. Plus it doesn't ever hurt to make an extra band and keep it in your bag for the day you might need it. I'm always over prepared when I go diving instead of under prepared.
