James Fisher and Sons, together with the Marine Corps Center, Panama City Division, developed a projection display – Shadow NAV, designed for combat swimmers working in poor visibility conditions.
Lack of light at great depth, turbid water, algae thickets in such conditions, sometimes have to operate the soldiers of the underwater front. The Shadow NAV helmet, created using the HUD (Head-Up Display) technology, does not depend on visibility conditions.
The display provides continuous display of compass readings, depth of immersion – in feet or meters, time in minutes and seconds and the level of battery charging. In addition, it uses weakly illuminated symbols to preserve the swimmer's night vision.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
