:shocked2: Nice work, you're a much braver person than I! I gave up diving in a wetsuit after it hit 10C and got a drysuit. It was one day were we were on our third long dive of the day and I was shaking so bad from the cold I couldn't take any more pictures and I thought "$1500 is not that much."Money well spent.
10C (50F)? That temperature is fine. My hands don't even go numb during a 30 minute dive.
I only have 12 dives in cold water. I'd say 90% of the guys I dove with used a drysuit. Watching them suit up looks really annoying. The cost of the suit is WAY more money that a good wetsuit. Most the guys complain about being just as cold as me when they are in the water. The only advantage I have seen is that getting out of your suit on the boat/shore is warmer because you are dry.
In my area, once the above water temperature drops below 5C (41F) it is too cold to get out of the wetsuit and a drysuit makes sense. However, NTD just pulled all the mooring buoys from the wrecks for the winter. So at this point I'd have to free descent in cold water, light to heavy current and poor viz. Skill level is not there yet. So I'll continue to dive wet. From May to September is fine because of the above water temperature is good enough to duff and don a wetsuit (10C+).
