So far, systems able to provide navigational data for submerged divers required either antennas, or sonar systems, making them big, heavy, complex and bulky. 

ENC3M- Electronic Navigation Console 3 Military is an innovation, packing a simple underwater navigation support system inside of a smartphone-sized core, which can be a platform for connecting external sensors- suited for the mission type.

Up to 100 waypoints, GPS float or rigid mast with hydrodynamic shape- for fast subsurface driving, speed sensor for full dead-reckoning navigation and all needed by diver data on one simple screen. Intuitive use allows to learn usage during one lesson.
