Extend your bottom time with NDL Aware depth metrics that work in real time to show how specific depth changes can impact your no-decompression limit (NDL).

POST-DIVE ACTIVITY GUIDANCE

Physical fitness is important for divers, but exercising shortly after a dive can increase the risk of decompression sickness. Post-dive activity guidance alerts you when it may be a good idea to postpone your training due to a recent dive.

SIDEMOUNT TANK SWITCH GUIDANCE

When diving with sidemounted tanks, receive visual guidance on your compatible Descent dive computer paired with a Descent^™ T2 transceiver as a reminder to switch tanks at a preset pressure value. This allows you to keep tank buoyancy balanced and properly manage a redundant gas supply throughout your dive.
