Safety Tips & Other Information

Diving longer and deeper safely

There are a number of techniques to increase the diver's ability dive deeper and longer:

* technical diving - diving deeper than 130 feet and/or using mixed gases.
* surface supplied diving - use of umbilical gas supply and diving helmets.
* saturation diving - long-term use of underwater habitats under pressure and a gradual release of pressure over several days in a decompression chamber at the end of a dive

Being mobile underwater

The diver needs to be mobile underwater. Streamlining dive gear will reduce drag and improve mobility. Personal mobility is enhanced by swimfins and Diver Propulsion Vehicles. Other equipment to improve mobility includes diving bells and diving shots.
