I have heard this argument many times against spearing on SCUBA and quite frankly am growing tired of it. I have been spearfishing for many years both as a freediver and a SCUBA diver and I can say from experience it is significantly easier to sneak up on a fish freediving than it is with a load of bulky, noise and drag producing SCUBA gear on your back. Anyone who claims that spearfishing on SCUBA is too easy has clearly never tried to catch up to a fleeing black grouper while wearing many pounds of steel on their back. It seems the OP's issue is really with spearfisherman having the audacity to infringe on the sanctity of "his" sport. Newsflash: the oceans belong to us all and my spearfishing friends have some of the most vested interests in preserving our natural resources of any divers I know. Spearfishing is the most selective form of hunting there is, eliminate the commercial fishing that has been indescriminately raping our seas for centuries and watch the seas flourish, even with those evil spearfisherman on SCUBA.
