    What you get

    Depth at a tap

    Tap anywhere on a map and read the depth in metres or feet, with the typical error for that map.

    Check your draft

    Enter the draft of your boat or board and see at a glance where you float and where you will not. Plan around the flats, not into them.

    Know when to go

    Every hour of the week scored for your kayak, board or boat from wind, waves, tide and daylight, with the hours you can pass over the shallows. Check your spot.

    How it works

    Honest depths, in three steps

    1

    We watch the water from space

    Many clear-sky pictures of the same coast, taken over the last year, are stacked so clouds, glare and boats disappear.

    2

    Colour becomes depth

    Shallow water looks different from deep water. A model trained on measured depths turns that colour into a depth for every point.

    3

    We check it, and show you the score

    Independent laser soundings along narrow tracks grade every map. The typical error is printed on the map, not hidden in a footnote.

    Watch your coast move

    One shoreline for every year since 2017, drawn from satellites, with where the beach retreats and where it grows measured every 50 m. Two demos are live: the Florida Keys around Marathon, and the Outer Banks at Rodanthe, where the sea is taking up to 28 m of beach a year.

    • 1,682measuring lines, Keys demo
    • 66 %of the Keys coast stable
    • 28 %of the Outer Banks retreating

    New · Fishing intelligence

    Where the fish are today

    Every depth map now ranks the species that live there from the depth and bottom they like, the water the satellites see today (temperature, clarity, plankton, fronts), the season and the tide, and draws where to look. Tap Fish on any map, or read the species pages: bonefish, permit, tarpon, snook, redfish, snapper, grouper, striped bass and more.
