The Descent X50i, Garmin’s largest dive computer, is operated via a large, vibrant 3-inch touchscreen that makes it easy to read multiple sets of data at a glance.

In addition, using sonar technology, divers can communicate with divers underwater via text messages and simultaneously monitor the other's tank pressure, depth and distance.

The computer is depth-rated to 20 bar, which corresponds to 190m. To handle the most technical dives, the Descent X50i is equipped with a strong sapphire crystal, leak-proof metal buttons and an additional dive light powerful enough to be used underwater.

Air integration requires pairing with a Descent T2 Transceiver, which is mounted in one of the second stage’s high-pressure outlets. Similarly, the user can monitor up to eight other divers’ cylinder pressure and depth and distance to the diver when they are also equipped with such a transceiver. The range is up to 10m. However, messages can be sent over a distance of up to 30m.

The computer is also equipped with preloaded bathymetric depth contours and over 4,000 dive sites worldwide as well as downloading nearby tidal data. 

Another significant feature is a 3D compass that can be used both above and below the surface.  Once divers are back on dry land, the dive log lets them review data, track gear, take notes and share details via the Garmin Dive app.
