No Decompression Limit Displaying --:--

The Descent™ Mk1 dive computer is able to display No Decompression Limit (NDL) time for dives. If NDL is above 100 minutes the Descent Mk1 smartwatch will display "--:--", see example below. This is by design, and similar to the function of other diver computers. For information on calculating NDL, refer to the owner's manual. 

For more information on your specific device, please see the owner's manual. To find the owner's manual, visit the Garmin Support Center, identify the specific device you are using, and select manuals on the left of the page. See the Related Content below.
