Hank49:If you just started diving you may want to try free dive spearing just to get the "feel" of it. Carrying a gun on scuba, hunting, shooting, getting a fish off the spear etc etc is a lot to do for a new diver just getting buoancy wired and not experienced at gas management etc etc.
OK, prepared to admit that there could be some different cultural issues going on here..... but why spearfish on SCUBA at all? It's not really sporting, is it? Certainly the norm here in NZ is to only spearfish whilst freediving. Turning up anywhere with a speargun and SCUBA is opening yourself up to ridicule......
