The future of
fishing connectivity.

Your boat, your sounder and your fishing friends, finally connected. Spartel turns every trip into data you keep: spots, catches, lures and conditions, logged in seconds and shared only with the people you fish with.

Why Spartel

Fishing has always been
a disconnected sport.

Waypoints stuck in a sounder. Catches lost in camera rolls. Conditions forgotten by Monday. Your friends’ best spots scattered across WhatsApp messages. Spartel connects all of it, in one app made by anglers.

Connected to your boat

Import and export waypoints and tracks with Humminbird, Garmin, Lowrance or Raymarine. Your sounder and your phone finally speak the same language.

Connected to your friends

Shared spots, shared catches, one leaderboard. Add your friends and everyone fishes the same story.

Connected to the sea

Wind, swell, water temperature and moon are saved with every fish, so patterns stop being a guess.

One app instead of five

Everything you pay for separately.
In one free app.

A logbook. A waypoint manager. A marine forecast with solunar tables. A trip tracker. A private network for you and your friends. Anglers usually juggle several apps and subscriptions for this. Spartel puts it all on one screen, connected.

Your points, your format

Export your spots.
Anywhere.

Your waypoints belong to you, not to a sounder brand. Import them from your Humminbird, Garmin, Lowrance or Raymarine, organise them in Spartel, and export them to any device in open formats.

  • Export one spot or your whole collection
  • GPX for plotters, KML for Google Earth, CSV for spreadsheets
  • Move your spots from one boat, or one brand, to another
