Military diving operations are routinely conducted in what can be one of the most inhospitable environments on the planet, frequently characterized by zero visibility. The inability to clearly see the immediate operational environment has historically been a serious limitation to manned diving operations — whether the mission is ship husbandry, underwater construction, salvage, or scientific research...
Military combat divers conduct underwater navigation missions in conditions with extremely poor visibility. Critical to the success of these missions is accurate underwater navigation, as well as staying within closed circuit oxygen rebreather depth limits. Unfortunately, handheld or tactical board mounted compasses, depth gauges, and chronometers can become virtually useless in the zero visibility...
Military, public safety and science divers conduct operations in what can be one of the most inhospitable environments on the planet characterized by extreme temperature, pressure, and extremely poor visibility. Handheld displays and gauges can be virtually useless in an environment frequently characterized by zero visibility, and this has been a serious limitation to underwater manned diving operations...
Maritime-Port Security Dive Operations cross many geographic boundaries and regional jurisdictions, and are conducted by US Navy Explosive Ordnance Disposal (EOD), United States Coast Guard (USCG), Federal Bureau of Investigation (FBI), and Public Safety Dive Teams (PSDT). They include underwater search of ship hulls, piers, pilings, docks, and bottom berthing areas for improvised explosive devices...
