It supports the management of 1 or 2 mixes (air, Nitrox and other mixes with O2 up to 99%), notifying the user at the most suitable time to change the mix. It has sound alarms and warning lights in case of violation of the decompression stop, excessive ascent speed and exceeding the maximum depth allowed for all mixes in use.In Gauge mode, the SEAC Screen computer displays depth gauge and stopwatch for fully independent dive management for more experienced divers.In Freedive mode, freedivers can view surface intervals and dive times, current depth and maximum depth reached during the session.The SEAC Screen dive planner allows you to simulate and plan a dive by displaying the NDL time based on a set depth and other data input (mixture, maximum PpO2, caution level).The Logbook records up to 40 hours of diving in Scuba/Gauge mode or 18 hours in Freedive mode.
