Seac APNEA is the new computer watch, entirely dedicated to the world of freediving and spearfishing. With an LCD screen with adjustable contrast and backlighting, APNEA contains all the important data during the session in the water, in a size that makes it the best readable instrument in its category. Important data during the dive such as descent speed, ascent speed, temperature, dive time, surface time and depth are complemented by other important data such as fresh or salt water setting and dive values. The MSST function automatically calculates recommended minimum surface recovery times and also alerts the freediver when it's time to hydrate. On the Seac APNEA computer you can disable all alarms, both visual and audible, while maintaining a continuous view of your session. The data of the dives in memory, can be viewed directly on the watch, or through the cable - sold separately - you can download them to your PC with the software available free of charge on the Seacsub website. Seac APNEA is available with either a silver satin finish or a black High Resistance finish (HR version) for added protection in case of scratches or shocks. Accessories sold separately: USB cable for data download and firmware update, strap extension.
