Hi Shadow,
Spearing with scuba is kinda frowned upon and illegal in lots of places in Europe as it makes it too easy in some cases. I,m not really a spearo anyway so it makes little odds to me. Waiting for the fish to come to you is usually done while freediving as they get curious about you and come in to investigate. If your on scuba the bubbles usually scare away any of the worthwhile edible fish that you may want. This is as far as i see it in my end of the world but I know in the states spearing on scuba is a lot more common.
Why not give the freediving way a try out to see if it succeeds? You dive down (doesn't have to be deep) and wait to see if they come in to you. As a safety note always give yourself plenty of scope to come back up again and never dive alone. There is a whole story on how to rig your gun with floats or reels etc but its not within my knowledge so try searching the hunting section.
