Seac Action Dive Computer

The SEAC Action is a wrist-mounted dive computer designed for scuba diving and freediving, featuring a black and blue color scheme and USB connectivity. This device integrates multiple operating modes for various underwater activities. The scuba mode utilizes the Bühlmann ZHL-16C decompression algorithm and supports the management of dive profiles with one or two gas mixtures, including air, nitrox, and mixtures with oxygen content up to 99 percent. It provides calculations for the no-decompression limit, monitors decompression stops, offers ascent rate warnings, maximum operating depth alerts, as well as no-fly time and desaturation time displays with altitude warnings. The depth gauge mode acts as a basic depth gauge with stopwatch functions for independent dive profile management. The freediving mode tracks dive time, surface intervals, current depth, and maximum depth. The device maintains a comprehensive dive log with 40 hours of detailed recording in 5-second intervals for scuba diving and 18 hours of activity logging in 2-second intervals for freediving. It includes a dive planner function for pre-dive planning. The unit features an LCD display with adjustable contrast and customizable backlighting for improved visibility under various lighting conditions. Built for enhanced durability, it operates with a long-lasting CR2450 battery. The included Dive Manager software for Mac and PC systems enables data transfer and analysis via the supplied USB cable. This software requires Windows 10 or compatible operating systems. The SEAC Action combines essential dive safety features with practical functionality for recreational divers and freedivers seeking reliable underwater instrumentation.
