The Suunto D6i Novo Zulu is a rugged military styled, watch-sized dive computer with a hard wearing webbing wrist strap. It’s steel case and anti-glare, sapphire crystal glass is rated to a depth of 150 metres.

The D6i range of dive computers allows you to select from a choice of 5 different modes of operation. AIR mode calculates gas absorption and release for divers breathing air while the Nitrox setting will allow you to programme and switch between three different nitrox mixes  to help you maximise your time underwater. If you select Free Diving mode the computer will record how many breath holding dives you made each day along with the surface time between each dive. In this mode you can access Suunto’s apnea timer feature which is invaluable when training with co/co2 tables. Switching to gauge mode will turn off any decompression calculations and the D6i will function purely as a dive timer and depth gauge during the dive. Off mode will prevent your computer switching from surface to dive mode whenever you take a swim or a bath.

It can be paired with Suunto’s optional Wireless Tank Pressure Transmitter, which allows you to wirelessly monitor your gas consumption during your dive and if you find navigating underwater a bit of a challenge you will love the integrated digital compass. D6i has a large memory, it can log up to 140 hours of dives. Your dive history can be transferred your tablet or desk top via a USB cable (included) and then reviewed using Suunto’s dive manager programme, DM5.

Suunto’s D6i is a desirable, classy piece of gear that is as comfortable on your wrist in your dive, or dinner suit
