Hand net is the easiest IMO, I used to dive for tropicals commerically when I was younger and we only used hand nets. Those slurp guns werent worth the plastic they are made out of. They are only good for baby high-hats or something really really slow.
I used to send the net up between rocks or block a small canyon and then chase the specific fish I was trying to get into the canyon. Since they can't see the monofiliment hand net they swim right in.
