Spearfishing Speargun with Rubber Sling by SO Dive with band, line & spear shaft - 14 Inches

easy to set, compact

I have taken this fishing for bass and ocean fish. Both times it just bounces off the fish, even from a few feet away. I even sharpened the tip with a file and still didn't penetrate. Goning to try a second band, hopefully that'll do the trick.

Not strong enough, rubber band is weak
