An adventure should take you anywhere, any way you want to get there. That's why Suunto D4i gives you great free dive features as well as the option of a wireless readout of your tank pressure and air time. Go with your own dive inspiration you'll be amazed at how far you can go on just one breath. The Suunto D4i also features an elastomer strap, ensuring maximum comfort as well as a superb fit. The case is made of a composite material with a mineral glass crystal and stainless steel bezel.
Diving is about freedom, adventure, and sharing your experiences. That's why, in addition to its existing dedicated free dive mode, the Suunto D4i features optional wireless air integration see SKU: SQTVTCT Suunto Transmitter. The D4i includes optional wireless air integration for easy monitoring of your tank pressure, so you can keep track of current cylinder pressure and remaining air time with a quick glance at your wrist, giving you more time to enjoy your dive. The easy-to-read dot matrix display and electro-luminescent backlight mean your dive-critical information including depth, dive time, and decompression status will all be shown clearly. In both air and nitrox mode, the clear, easy-to-read screen displays your current and maximum depth, current time, dive time, decompression time, and temperature. Audible and visual depth and time alarms warn you when it's time to start your ascent. In nitrox mode, you can maximize your dive time by adjusting the oxygen content of your gas between 21% and 50% and your PO2 limit between 17.4 psi and 23.2 psi (1.2 and 1.6 bars).
With its innovative free dive functions and dedicated free dive mode, Suunto D4i is also perfect if you're serious about breath-hold diving. Programmed to sample depth three times a second, Suunto D4i records highly accurate data on the true depth reached. Using the Suunto Deep Stop RGBM algorithm, Suunto D4i enables continuous decompression for optimal ascent time. For deeper dives, the deep stop option adds further protection with a series of deep stops between your maximum depth and ceiling. You can test upcoming dives and view no-decompression time data for different depths before getting in the water with the built-in dive planner. After your dive, you can easily transfer your dive data to your computer for further analysis using the optional Suunto DM4 software, which includes a detailed logbook featuring a graphical representation of all your dives.
The D4i Dive Computer is a compact watch style computer that measures 1.91" (48.6 mm) in diameter with a thickness of 0.63" (16 mm) and weighs a mere 3 oz. (85 g) so you can wear it every day as a timepiece. Computer has an operational depth display from 0'- 328' (0 -100 meters) and in Gauge Mode will display as deep as 492' (150 meters). Computer is altitude adjustable to 10,000' (3,000 meters), has a 12/24 clock function, stopwatch, ascent rate monitor alarm, ascent time display, audible alarm, deep stop function, full decompression data, log book memory of 140 hours, maximum depth alarm, personal adjustment features, safety stop function, and displays temperature.
The Suunto Reduced Gradient Bubble Model (RGBM) is a modern algorithm for predicting both dissolved and free gas in the tissues and blood of divers. It was developed in co-operation between Suunto and Bruce R. Wienke BSc, MSc, PhD. It is based on both laboratory experiments and diving data, including data from DAN. Computer is powered by a CR2450 lithium battery, has color strap options, quick guides, and scratch guards.
This product has a limited warranty of 24 months.
