You can use your Suunto 9 Peak Pro for snorkeling and mermaid diving. These two activities are normal sport modes and are selected just like any other sport mode, see Recording an exercise.
The Suunto 9 Peak Pro is capable of measuring depth up to 10 m. It is however waterproof up to 100 m according to ISO 22810.
These sport modes have four exercise displays that focus on dive related data. The four exercise displays are:
The touch screen is not activated when the watch is underwater.
The default view for Snorkeling and Mermaiding is the Surface view. While recording the exercise, you can browse between the different views by pressing the middle button.
Suunto 9 Peak Pro automatically switches between surface and dive state. If you are more than 1 m (3.2 ft) below the surface, the underwater view is activated.
When using the Snorkeling mode, the watch relies on GPS to calculate distance. Because GPS signals do not travel under water, the watch needs to come out of the water periodically to get a GPS fix.
These are challenging conditions for GPS, so it is important that you have a strong GPS signal before you jump in the water. To ensure good GPS, you should:
After you selected the Snorkeling mode, wait at least three minutes on land before starting your activity. This gives the GPS time to establish strong positioning.
During snorkeling we recommend resting your hands on your lower back for efficient water movement and optimal distance measurement.
Suunto 9 Peak Pro is not for certified scuba divers. Recreational scuba diving may expose the diver to depths and conditions that tend to increase the risk of decompression sickness (DCS) and errors that may lead to serious injury or death. Trained divers should always use a dive computer developed for scuba diving purposes.
