diving equipment while immersed in water to a maximum depth of 10 meters.
This device is not a dive computer or a standalone product for measuring any
certified scuba diving activity. SUUNTO 9 Peak Pro is only for recreational use
and not meant for medical purposes of any kind.

can be between the sensor and your skin.
• The watch may need to be higher on your arm than where watches are
normally worn. The sensor reads blood flow through tissue. The more tissue
it can read, the better.
• Arm movements and flexing muscles, such as gripping a tennis racket, can
change the accuracy of the sensor readings.
• When your heart rate is low, the sensor may not be able to provide stable
readings. A short warm up of a few minutes before you start the recording helps.
• Skin pigmentation and tattoos block light and prevent reliable readings from
the optical sensor.
• The optical sensor may not provide accurate heart rate readings for
swimming and freediving activities.
• For higher accuracy and quicker responses to changes in your heart rate,
