You take the good with the bad when it comes to reviews. Today I received a message from Alex voicing his dislike of the NAVMAN M300. The device is designed for water sports enthusiasts and uses the GPS to provide lap time information. It can display in both miles and knots, measures current, maximum, average speed and distance as well as your current heading and an automated timer. Alex writes:

  • [The NAVMAN M300] records max and average speed but you can not see what lap was fastest and max and average speed per lap. The lap info it can store is distance and time(duration) of the lap only.
  • Being a “tool for windsurfing”, as they advertised, it does not have even a primitive start sequence countdown timer.

Perhaps something like the Garmin Foretrex 201 would have been a better option although I have not used on yet myself.

  1. Hi,
    It is Alex again! Seems like I can not stop!
    Garmin Foretrex 201 is a much better unit, but, again but, not 100% for windsurfing 🙁
    1 – it is only splash proof (M300 is better in this department);
    2 – it is not strong (mechanically) enough, my mate was wearing it on the arm, hit the mast and cracked the board inside (M300 is better in this department too).
    3 – it has got pins like an ordinary watch fitted in the plastic body – and the plastic breaks. I saw blokes wrapping pieces of bicycle inner tyre around for better security.
    Verdict: great ton, but not for windsurfing.
    If somebody can only make a cross between M300 Navman (body and display) and Garmin Foretrex 201 (braind and downloads) with added stopwatch vibration… please let me know.

  2. I purchased a Navman M300, have used it twice and the unit has failed to work because it has taken on water. I am sure it is off warranty but I’m hoping I can find a place to have it repaired/refurbished so that it will work again. I found its operationj satisfactory but not its advertised water-resistance.

  3. We used the M300 at a windsurfing race, sponsored by Navman. Out of 10 units, 6 failed the same day because they took water inside. The battery seal is so bad! I called the company and they told me that it is not waterproof… made for windsurfing but not even water resistant?
    I was able to convince them to give me a replacement, one replacement. I have used the unit for running 3 times and the display already failed. It does not display the large numbers, so forget about getting your top speed, etc.
    It is the worst product that I have even seen…
