Personal underwater heating system set Mangrove DEH-PEH7-WS for wet suits, which includes:

Modern SCUBA equipment has led to a large increase in the dive times. Only 30 years ago, a dive longer than 40 minutes was considered exceptional, but today, if you carry plenty of gas, dives exceeding 2 hours are not unusual. The cold, however, remains a problem. While drysuits and undersuits have improved over the years, after an hour or so even the hardiest of divers will start to cool down. More layers will help will help, but the resulting increased buoyancy can cause more problems. A solution is to use the Mangrove heated undervest DEH.

The Mangrove DEH is a state of the art power heated undersuit, that allows to turn any standard wet and drysuit in to a much more comfortable heated suit. Worn underneath a wetsuit, it creates a thermal layer between the body and your wetsuit for a much more pleasurable and warmer diving experience. The system warms to 42º C using any of the available battery packs and keeps the core body temperature warm. Its unique rubber heating element technology guarantees that it is completely safe totally immersed in water. One size for men and women fit all. The DEH can be also used with drysuits by means of the drysuit transition system CEH-DS.

The Mangrove DEH heating system gives you super warm and allows you to enjoy cold water activities easily. This is a lot of heat considering that the human body produces in the relaxed condition, only about 60 Watts of heat. With the proper heater you can dive wet in North Pole waters and enjoy unprecedented comfort. Supplemental heat is the future of diving!

Scuba diving is a beautiful and exciting sport. We need to be warm to maximize our enjoyment. There are sometimes rough seas, cold water, strong currents, bad visibility, and gloomy weather and sometimes you get cold. There is not much we can do about the diving conditions, but you can always dive warm. The new technology is here and it is for everyone.
