a diver who wear a red viking drysuits try to dive into deep sea only use simple scuba gear to rescue the diving bell. But he fail,it is too deep for only use normal-air,so he dead in his drysuits.
Because the deep sea diver wear hot water suits, not drysuits. The hot water suits use hot or warm water from the tube to keep diver`s body warm when the diver work in a cold and deep water. Two divers in the bell were save,but the rescue diver was dead...
a diving bell is a chamber under pressure. its dropped on the bottom or suspended at a certain depth to be used as a base for deep sea divers. its used allot in commercial diving when welding on oil rigs and such.
