A new Garmin update, system software 25.15, is rolling out to one of the brand’s wearables. It tackles a range of bugs, including one linked to a map feature.

The Garmin Descent Mk3 and Descent Mk3i watch-style dive computers are receiving system software 25.14. This release arrives several months after the last, system software 23.49, which brought several bug fixes and improvements linked to connected devices.

Now, with system software 25.14, Garmin is tackling more bugs experienced by users of the Descent Mk3 and Descent Mk3i (curr. $1,399.99 at Amazon). Firstly, the company has resolved an issue with the shading of the bathymetry contour lines on the DiveView map. There is a fix for a dive computer error, which occurred when users switched to an oxygen diluent in a CCR dive.

Garmin has removed recovery time inconsistencies, shown in the Descent Mk3/Mk3i’s Dive Readiness widget. On top of this, an issue where some S1 buoy strings could be cut-off in certain languages has been resolved. Plus, a problem where the total dive count increased unexpectedly when recording dives in pool mode has been sorted out.

System software 25.14 is rolling out to users of the Garmin Descent Mk3 and Descent Mk3i watch-style dive computers in phases. When available, the update should be pushed to the wearables automatically when connected to Garmin Connect or Garmin Express.
