The biggest challenges is oxygen and nitrogen concentration. Oxygen becomes toxic at two atmospheres or about 300 feet since it is 1/5 atmosphere at the surface. Nitrogen is dangerous at lower concentrations if the diver doesn't rise very slowly. It also become like a narcotic about that depth. It is possible to regulate the concentration and use helium and selected gases and you can go down to at least about 1500 feet.
