Dear Undercurrent,

Regarding your April article on wetsuits, it was spot on! Being someone who is always cold, it's been a challenge for me to stay warm underwater, particularly on dive trips when my husband and I routinely do four dives per day, at an hour-plus per dive.

After three or four days, I am shivering even in the warmest water. Diving in places like Galapagos, Cocos or Socorro was just painful for me, and although I would persevere, it took a lot of the joy out of the dives. On our first Socorro trip, one of the other guests was using a Thermalution heated vest. She took pity on me and was kind enough to let me use it on one of the dives she sat out. The first thing I did upon returning home was to order one. After using it for about five or six years now, I never dive without it. Although they are not cheap, they are worth every penny if you are like me and always cold."

John Bantin replies: I've used these vests in conjunction with both wetsuits and drysuits. And when I've dived under ice without gloves, I found I had warm hands, thanks to Thermolution's far infrared technology warming my blood.

Divers Who Don't Know Dump Valves

Dear Undercurrent,

Regarding your May article about dumping air from your BC, I was amazed to find out that a woman on my last dive trip who was having trouble maintaining her buoyancy had no idea what a dump valve was, or that her BC had any, let alone four of them. After showing her a picture I took of her holding her inflator hose up with an elbow (bend) in it because it was much longer than her arm, I explained how dump valves work. After the next dive, she thanked me and was amazed that no one ever mentioned using them to her before....
