Recreational Open-Circuit Features
Key features of the Recreational Open-Circuit mode (aka Recreational Nitrox mode) include a simpler menu structure, less cluttered display with a larger font and configurable bottom row, optional safety stops, and a no-decompression limit dive planner. The simplified settings allow for three breathing gas mixtures (Air or Nitrox) and places a greater emphasis on the maximum operating depth (MOD) and no decompression time limit (NDL). The display prominently warns the diver if their depth is near, at or exceeds the MOD of the selected breathing gas. Optional safety stops are user configurable to be 3, 4, 5 mins or adaptable. When using the Adapt setting, a 3 minute safety stop will be used, unless the dive exceeds { 100ft | 30m }or the NDL falls below 5 minutes, in which case a 5 minute safety stop is used..If the diver exceeds the NDL and requires stops, the display turns red and warns "DECO STOP" with the mandatory depth and stop times.
