The SEAC Apnea dive computer is the new diving mate for freedivers and spearfishers. It is easy to use and features a lot of key functions. The SEAC Apnea constantly monitors and records dive values to provide in real time - and save in archive - full details on performance and safety. Activity data can be recorded every second or every 2-seconds, depending on the dive. Main information details are all on the same screen, visible at a glance: dive and ascent speed, temperature, dive time and surface time, depth. The MSST function automatically calculates the minimum recommended surface recovery times. The software also warns the freediver when it is time to rehydrate. Users can deactivate all the light and sound alerts, while maintaining the continuous control of the dive profile on the display. The extensive internal memory of the SEAC Apnea records up to 500 dives (this number may vary, depending on the memory space occupied by a single dive) that can be checked directly on the display. In addition, to compare the performance details, just connect the SEAC Apnea to your PC or Mac (USB data cable sold separately), download all the sessions and dives and easily view your data on the logbook’s graphic interface. The SEAC Driver works with a standard CR2032 user-replaceable battery and is 100m water resistant.
