USN, JFD develop combat-navigation module for divers

21 September 2018

The US Navy (USN) Naval Surface Warfare Center – Panama City Division and subsea-capability provider James Fisher and Sons’ JFD have developed an advanced hands-free combat diver navigation module called Shadow Nav.

Designed to help divers conduct accurate underwater navigation missions in hazardous conditions with extremely poor visibility and remain within closed circuit oxygen rebreather depth limits to prevent oxygen toxicity, the Shadow NAV ensures the ability of divers to have continuous visibility of accurate information, according to the company.

The inability of current handheld or tactical swim board mounted compasses, depth gauges, and chronometers to provide divers information in zero-visibility environments limits the ability of the divers to complete missions.
