The Reef dive instrument created by Linde Werdelin, has been carefully designed to provide realtime guidance to divers, tracking the critical pieces of information needed on any dive by using several sensors, a sophisticated low power multi MPUplatform, an advanced 3-axis compass and alarm systems etc.

Presenting the information by using strong graphical displays in colour, The Reef features the divers; depth, ascent rate vs. ideal ascent rate, dive time, decompression stops, no fly time, temperature, maximum depth, sur face interval times, alarm/ warnings, timers etc, constantly keeping the diver in a real time picture. The Reef also logs vital data and events on the internal logbook and continuously updates the overall dive statistics for the diver to access at a later point. The logbook has the capacity to store up to 5 days of continuously logs with a sample rate of one log per second.

Cased in lightweight aluminium, diving professionals as well as enthusiasts, can now choose from a wide range of aluminium finishes and colours including black DLC with 18 k rose gold pushers.
