Small wrist top GPS receiver with easy to read display, electronic compass, barometrical altimeter and USB interface. Optional heart rate and cadence sensor.

The GARMIN Foretrex 401 is very easy to use, supports multiple languages and has an extremely sensitive antenna. It is the perfect partner for any outdoor activities. It helps to navigate and displays and records information about your movement, such as the current heading and speed, the travelled path (track), maximum and average speed etc. As an enhancement over the Foretrex 301, the Foretrex 401 has an electronic compass, a barometrical altimeter and it can receive data from an optional heart rate monitor and an optional cadence sensor. The built-in USB interface provides data exchange with a PC.

GARMIN Foretrex 401


  • Wrist top device, robust, very handy
  • Easy to read display with background illumination (100x64 pixels)
  • Multilingual user interface in Czech, Danish, Dutch, English, Finnish, French, German, Italian, Norwegian, Polish, Portuguese, Spanish and Swedish
  • Integrated 12 channel GPS receiver with very sensitive built-in antenna
  • Electronic compass to check heading while not moving¹ (can be turned off so safe power)
  • Barometrical altimeter for precise elevation recording²
  • Heart rate monitor, requires optional chest belt with heart rate sensor. The chest belt uses a digitally coded signal, which means, once a heart beat sensor and the GPS have been paired, the GPS will never receive a conflicting signal from another sensor. So you can exercise in close proximity to other sensors without fear of interference.
  • Speed and cadence monitor, requires optional speed and cadence sensor. Measures the number of revolutions of the back wheel and the crank arm with magnets and a wireless sensor. Like the heart rate monitor, this sensor uses a digitally coded signal. Once paired with the Oregon 550t, the GPS will never receive a conflicting signal from another sensor. So you can exercise in close proximity to other sensors without fear of interference.
  • Powered by batteries (2x AAA, last about 17 h)
  • Short time to first fix (TTFF¹: approx. 15 seconds after a warm start, meaning there are valid coordinates of the satellites available, or approx. 45 seconds after a cold start, meaning there are no valid coordinates of the satellites available)
  • Supports WAAS/EGNOS
  • Supports more than 100 different datum (coordinate systems)
  • Supports various display formats include the Swiss Grid
  • Firmware stored in Flash-Memory, can be updated by the user
  • Operating temperatures -20 .. 60°C (-4° .. 140°F)
  • USB interface (connection cable included)
  • Dimensions: 74x44x23 mm (2.93x1.65x0.89 inches)
  • Weight: 64 g (2.26 ounces)
  • Water resistant up to approx. 3 feet (1 meter) for about 30 minutes (IPX7)
  • ¹) In order to check the heading with a GPS, a minimal movement with a speed of at least 5..8 km/h (3..5 mi/h) is required. Where no movement is not possible, a compass is needed.
  • ²) Even though a GPS provides accurate elevation information, the value slightly varies continuously. A barometrical altimeter is therefore more accurate, especially when summarizing elevation changes.
  • ³) TTFF: Time To First Fix, time until the first information about the current position is acquired.

Information for navigation:

  • Stores up to 500 waypoints with name (up to 8 characters), icon (choice of 31 symbols) and coordinates
  • Stores 20 reversible route with up to 125 waypoints per route. Shows the current position in relation to these waypoints (direction and distance)
  • Current position (longitude, latitude, altitude)
  • Current accuracy of the position information
  • Information about the course (turn, off course, to course)
  • Estimated travel time to the next waypoint, rsp. to the final destination
  • Estimated arrival time at the next waypoint, rsp. at the final destination
  • Current time
  • Current bearing
  • Current, average and maximum speed
  • Trip duration and distance (Odometer)
  • Stores up to 10'000 track points in up to 10 tracks (travelled path)
  • Time of sunrise and sunset
  • Supports metric, nautical and U.S. units
