That'd be just fine with me...the good thing about diving with spearos or formal spearos is the high liklihood (in my experience) that their diving skills are often well developed and they won't freak out when something unexpected happens.
With photography, all I got was film, processing and tons of not-very-good pics - maybe one good one out of 5 rolls or something like that...and that was in exotic, caribbean locations with 100 ft plus visability!!!
My odds of coming home with something I could actually use, like fish for dinner that was SO much fresher and enjoyable than the stuff they sell at grocery stores, were much better than getting a pic...plus at least I know where it came from and how it was treated...which for me is a big plus. Also, never take more than I can use....or share with friends!
