If you're cold-tolerant, you'll likely start to shiver or even lose your sense of where you are. As with "cold water," everyone has a different tolerance for cold water. Having sealed gloves, a dry hood, a full face mask, and an extra thermal layer helped me stay warm when I was in sea water that was 38 F. All of that made it hard for me to move, reach, hear, and be nimble because I was overprotected and didn't know how to adapt to diving in cold water in a new way. When I was outside, I was wearing a dry suit that had a thick hood and gloves made from a wetsuit. I also had one layer of thermal underwear and gloves that were heated inside my mittens. If I need to be more dexterous, I could take off the gloves for a short time.

You do know this is about an RC submarine and not SCUBA diving, right? Unless I missed something.
