Icon HD net ready is the new frontier in gas integrated computers. Whereas until now the dive computer was simply a passive receiver of information, with the new Mares bi-directional technology, Icon HD is ready to communicate actively with the tank module for an unprecedented level of safety and user friendliness. The combination with icon's high definition color display brings tank pressure information to a new level. Detailed numerical information is accompanied by intuitive, at-a-glance color coding. Blue and green means the pressure is above the mid tank warning, red means the pressure is below the reserve, orange and yellow for values inbetween. The thresholds are set by the user for maximum customization.
