The Reef is Linde Werdelin’s dive instrument designed and developed in-house to provide the most sophisticated tool to scuba divers.

It tracks all critical information by using several sensors, a sophisticated low-power multi MPU platform, an advanced 3-axis compass and alarm systems. Using an LCD colour screen protected by a sapphire crystal, The Reef encompasses the most advanced features that constantly keep the diver in a real-time picture.

The Reef records vital data on its logbook and continuously updates the overall dive statistics for the user to access and download on their computer.
