I've been tempted to do a shrimp dive, but you have to go down to 120-130 feet deep and wave a green glo-stick around as they get attracted to it, you scoop them up with a net, but that sounds like alot of work, I've been down to 150 foot deep so it's not the depth, but still, it does get spooky dark that deep.
I'll stick to the crabbin'.......some people from boats lower shrimp pots, but they drop them down to 200+ feet deep, and it's WORK pulling a loaded shrimp pot up from that depth. Most people use a gasoline powered winch drum if they're serious.
Crabbing works for me. Might go out this Wednesday for hopefully another limit, easy pickings. Fun to dive for them, but even that is work too being fully suited up in a drysuit, wearing about 100 pounds of dive gear along with 36 pounds of lead weight, packing it all on your back the 100+ foot down the beach from the car. You're spent tired at the end of a 50 minute dive too.
yeah, live crab boiled up all of 2 hours old out of the water, doesn't get much fresher than that.
