one of the first diving suits was made of leather. sixty - foot breathing tubes connected to the suit. oxygen was pumped through the tubes, enabling the diver to breathe underwater. a major improvement to the diving suit was the metal helmet. this permitted the diver to endure greater pressure and to explore deeper underwater environments. but divers wanted a more convenient way to breathe underwater. eventually, air tanks that divers could carry on their backs were developed. why couldnt divers venture into deeper water without helmets? 1 they needed helmets to carry oxygen. 2 the pressure of the water was too great. 3 the breathing tubes were not convenient.
