Product description of SEAC Computer Apnea HR dive computer

Description summary

Unleash your freediving potential with the SEACSUB Apnea HR, a precision dive computer and sports watch. Track crucial dive data like descent/ascent speeds, depth, and time on a single, clear display. Its high-visibility LCD is readable in all conditions, and silent alarms aid stealth. Beyond diving, it features a pedometer and standard watch functions. With a logbook for 999 dives and customizable alerts, the Apnea HR is your reliable partner for exploring depths and daily life

SEACSUB Apnea HR Freediving Computer | Precision, Safety, and Performance

Elevate your underwater passion with the SEACSUB Apnea HR, the ultimate dive computer designed for the dedicated freediver and spearfisherman. Engineered for performance and built for reliability, the Apnea HR is your essential partner for exploring the depths safely and pushing your personal limits. This advanced computer combines sophisticated dive tracking with daily watch functionality, all housed in a sleek and robust design with a diameter under 50 mm, making it comfortable for both deep dives and everyday wear.

Experience unparalleled clarity and control during every phase of your dive. All critical information—dive/ascent speeds, temperature, total dive time, and depth—is displayed on the same screen. This intuitive layout means you get a complete, at-a-glance overview of your dive profile without needing to switch between screens, allowing you to stay focused on your technique and the environment around you.

The high-visibility LCD screen with adjustable contrast and backlighting intensity ensures perfect readability in all conditions, from bright surface sunlight to the dim light of deeper waters. We understand that stealth can be key, especially for spearfishing. That´s why all illuminated and sound alarms can be deactivated, allowing you to approach your prey silently and without startling them. When you´re back on land, the Apnea HR transitions seamlessly into a feature-rich sports watch. Track your daily activity with the integrated Pedometer, and utilize standard watch functions like dual time, a stopwatch, and a countdown timer.
