SEAC Screen wrist diving computer. The large display shows all the main information in one view, with clearly readable and distinct characters. Contrast and brightness can be adjusted, as well as the light mode (automatic or manual) and the backlight time (from 2 sec to 60 sec). The display measures 4 x 4.7cm and is protected by a sturdy rubber housing. The two well-defined front buttons let allow the SEAC Screen to be managed quickly and easily even with very thick gloves. SEAC Screen operates in 3 main modes: Scuba, Gauge and Free dive. In Scuba mode, the dive profile is completely managed according to the Bühlmann ZHL-16C decompression algorithm. 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 Free dive mode, free divers 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 Free dive mode. Downloadable data via USB (sold separately). Firmware update and SEAC Dive Manager software are available online (free download at Seacsub.com). SEAC Screen works with a CR2450 battery and is user replaceable. Maximum depth 100 meters, calculation of No Fly and Desaturation times, maximum allowed altitude warning, fresh or salt water selection.
