I'm getting back into diving after several decades and need help on getting just what I need in the way of wetsuits. I live in NW Arkansas about 40 minutes from Beaver Lake Dam. I'd like to think that I'll dive the lake often and year long (as much possible). The reality may be that I get bored with the lake since it's not like the ocean. What do you recommend for must-have exposure suits and possible combinations with hoods or hooded vests? 3mm, 5mm, 7mm? (I tend to run cold these days) I was originally thinking of getting a drysuit, but the cost and the fact that few people around even use them makes me wonder if it's worth it. My two LDSs don't even sell them anymore. because they didn't sell.
I need suits for the local lake as well as for a trip to the Bahamas mid-July. I expect to eventually get to the Red Sea, and various places in the Carribean during any month of the year. Also, since my daughter lives in Chicago, I expect to do some wreck diving in Lake Michigan on a charter when I visit.
The water currently is 42 at 60 feet in Beaver Lake. Very few divers this time of year. In summer the surface gets to the 80s, but then there are a few thermoclines as you go down. I don't know what the temp range might be.
What should I have in my exposure-suit arsenal (without over buying)?
