Recently in Cozumel my wife's Wisdom 1 Dive Computer stopped working mid-dive.It will not turn on with the front button.With the side button it counts down with some numbers jumbled then turns off again.I've changed the battery to no avail. It will sometimes flash through different screens without stopping.Its only 3 years old with about 100 dives on it. Since its past warranty,do I now have an expensive doorstop?
