I too dive. I crew for fun on the Dina-Dee out of Pt. Pleasant, NJ. Mostly onshore wrecks in 60-90' as that's all there is except for sand bottom. Jersey shore bottom temps peak in the mid sixtys, so dry suits are the suits of choise. I usually go for lobster, sea bass, blackfish (AKA tautog, my favorite fish), or mussels. On a good night I'll only make enough in tips for dinner and drinks afterward, but at least I get a free ride. Visibility can be pretty iffy. The boat rules say that if I can't see my fins on the bottom, I abort the dive and blow the anchor back to the surface. A great night will have 40 to 50' vis, but normal is 15-20'. Not great, but if you want to dive often, you have to dive where you live.
