@Mff73 The Suunto Ocean dive computer uses different sampling rates for scuba and freediving modes to match the demands of each activity. In scuba mode, the device logs dive data at 10-second intervals, balancing data detail with battery efficiency for longer dives. In contrast, freediving mode records data every 1 second to accurately capture rapid depth changes and short dive durations. These rates apply to key metrics such as depth, time, temperature, and heart rate, and are stored in the logbook for later review. Currently, these sampling rates are fixed and not user-adjustable. Some other dive computers have adjustable and higher sampling rates.
