No way of changing the compass direction indicator. You have to turn it off if you’re going southbound. If you want to change directions northbound, then you’d have to turn it back on again before continuing your trip.

The transducer has to be calibrated every time you change depth or move to a new location. This prevents it from providing an exact reading and can be a bit inconvenient.

The FON 100 is a great tool for divers who want to keep track of their location and depth at all times. It’s compact enough to carry around everywhere but still provides detailed information about your surroundings. The display screen is large enough for even deep dives and you can even connect it to your phone if you want to take pictures or record videos while underwater.
