Garmin Descent™ X50i Premium Dive Computer

The Garmin Descent™ X50i Premium Dive Computer features a vivid 3-inch color touchscreen for clear data visibility underwater. It offers SubWave™ sonar-based diver messaging and multiple dive modes to suit various diving conditions. DiveView™ color maps provide detailed depth contours and dive site information, while an integrated backup dive light ensures safety in low visibility. With Air Integration via Descent™ T2 transceivers, this advanced device delivers comprehensive dive monitoring for professional and serious recreational divers.

3-inch Vibrant Color Touchscreen Display
The large color screen allows for more data to be visible and makes critical information such as the projected ascent dive profile and in-dive depth chart easily readable at a glance. And the touchscreen makes setup easy above the surface.
