Description
Seac Action HR Dive Computer is a wrist-mount computer designed for scuba and freediving, providing clear, on-wrist data for dive planning and real-time monitoring as part of your diving gear.
Three main modes cover the needs of divers: SCUBA mode manages recreational dive profiles with a Bühlmann ZHL-16C algorithm and supports 1 or 2 mixes (air, Nitrox, and O2 up to 99%). GAUGE mode functions as a depth gauge and stopwatch for standalone dive planning, and FREEDIVING mode tracks dive/surface time with current and maximum depth.
Memory and safety: logbook memory includes up to 40 hours in SCUBA mode and 18 hours in Freediving mode with regular dive records; safety alarms cover MOD exceeded, deco stop violations, ascent speed, NoFly time, and desaturation calculations, plus an altitude warning and an NDL-only Dive Planner. A Dive Manager software for Mac/PC (Windows 10 required) lets you review dives, and data can be downloaded via USB cable (sold separately).
The device features an ultra-durable structure with improved resistance to blows, corrosion, and temperature swings, along with an LCD screen with contrast and adjustable backlighting and a long-lasting CR2450 battery. The Seac Action line is available in two variants: ACTION with stainless steel crown, buttons, and buckle, and ACTION HR with HR-treated case.
