POSEIDON DIVE COMPUTER 
 
The M28 was born out of the vision to create a dive computer that acts merely as an extension of the diver. Silently monitoring, only to be seen at a glance yet convey every bit of information the diver needs. On the surface the M28 displays simple, intuitive graphics under a clean slate of glass and an easy-to-use two-button control. Look on the inside though, and you will find one of the most powerful dive computers ever made. Digital compass with tilt-compensation, dual deco algorithms, capable of controlling a rebreather and guiding every dive profile. Pure excellence in a shell of simplicity.
