See the bottom before you cast.

Depthrix is a depth chart app for lakes and rivers. We survey the water ourselves and draw contours to 1 ft over the map you already know, and it all works offline on the water.

We will email you when Depthrix launches and when we map new lakes, nothing else. Your lake helps us choose where to survey next. Unsubscribe any time. Privacy Policy

What is coming

A chart of the bottom, not a guess.

  • 01

    Surveyed by us

    We map lakes from the boat. Where we have surveyed, our chart replaces the coarse public one, with contours to 1 ft.

  • 02

    Offline on the water

    Install a chart once and it works with no signal and no sign-in, for as long as you are out.

  • 03

    Tracks, waypoints, GPX

    Record where you have been, mark what you find, and move it to and from your chartplotter.
