I am thinking of getting into spearfishing. I am looking at some Mako gear(predator pro 110). Could someone please explain to me the difference between closed and open muzzles? I don't know which one to choose. I have enough freediving gear and all i need is a gun and reel. Also what's the deal with bands? I understand it's different levels of power, but i still don't understand the levels.
Thanks
Thanks
