iDive Tech+ Color Series

The Ratio iDive Color Tech+ Edition is packed with more features than any comparable computer. The Ratio iDive Color Tech+ Edition has all the features any technical diver will ever need with up to 10 gas mixes enabled. iDive Color Tech+ Watch dive computer: For skilled divers only. Are you? Air, Nitrox and Trimix Closed Circuit Rebreather (CCR), 10 mix, Air integrated, compass, outdoor functions and more. Computer also offers a gauge and freediving mode.

The iDive Color Tech+ Dive Watch Computer can be used with up to 10 gas mixtures (O2: 05% – 99% / He: 0% – 95%) Fueled by the Bulhmann and VPM Algorithms with the deco model (Algorithm) Buhlmann ZHL-16 B + VPM-B. User settable gradient factors for Buhlmann user settable bubble radius for VPM. Repetitive dives management, gas switch and Gas break during the dive, PO2 0.4 – 1.6, CNS calculation and altitude adjustment is automatic.

The iDive Color Tech+ Dive Watch Computer can be set for fresh or salt water and measurements for depth, temperature and gas pressure (w/optional transmitter) in imperial or metric increments. Time can be set in a 12 or 24-hour format with dual time function, daily alarm functions a two-time zone function. The computer has a deep stop function, adjustable safety stop function for time and depth, last decompression stops depth manual adjustment and both audible and visual alarm/alert functions. There is a dive planner no decompression limit + full decompression planner. Navigation is easy with the 3D-compass that has a 1° resolution, +/- 1° accuracy. Other functions (Apps) stopwatch, pitch & roll, magnetometer and lunar phases. Maximum depth is 721′ (220 meters), the computer has a logbook of 160-hour on Scuba (sampling 10 sec), backlight LED super-bright activation mode timer, manual on & off, that’s always-on in the water. Powered by a rechargeable lithium-ion battery that provides 20-hours of dive time and 1 to 2-months (watch-mode. Charging is performed via the included USB cable.
