re: Scuba Divers?

Observe a few times, get used to currents on surface vs below and diving in some low vis conditions, start small on fish and work up and don't be afraid to let go of a rig if you get in trouble. Live to shoot another day. Check local dive shops for charter trips and develop a network that way.

Rig diving in Louisiana is great and offers a lot of opportunity to spearfish. Just needs to be respected that's all. Enjoy it - not much else like it!
