Functions: altimeter, barometer, temperature, weather forecast, stopwatch (Chrono), lunar phases, alarm clock dual time
Extra fitness functions: pedometer, distance, speed, calories burned
Freedive functions: special algorithm that calculates the minimum recovery time between dives to minimise the risk of Taravana and Hemoptysis.
TSF Tissue Saturation Factor: utilizes dive time, depth, dive speed descent and ascent, and the dynamic of your dive .
Hypoxia Factor:depth and duration of the previous dive
Dehydration Factor: number of dives done, depth and duration of the dives.
SEAC Jack analyses all the key factors of the dive and the freediver to reduce the risk of developing pulmonary edema and hemoptysis. Just set the depth you want to achieve and your computer will guide you through the first three dives to warm up” your pulmonary capillaries.
After each dive, it will suggest the minimum recovery time. Once it is completed, the computer displays the actual surface time.
Alarm functions: depth, fixed step goal notify, dive-time, hydration
