Cochran EMC-20H

Base Model Configured for AIR .....

The Cochran EMC-20 is the simplest of dive computers to use and understand, even for beginning divers. It is ready-to-use straight out of the box. Merely understand the large easy-to-read display and audible warnings.  But don't let ease of use minimize the sophistication of this tool that is also used for the most demanding technical and military dives.

The intelligence built into the Cochran Commander manages everything else. It automatically, seamlessly, and constantly adapts to your personal diving style, water temperature, salt/fresh water, ascent rates, and altitude . It even has a built in 'Flight Data Recorder' that records changes in altitude during your flight to and from the dive destination. (Eighteen percent of the DCI incidences occurred during or immediately after a Post-dive change of altitude.)

Multi-blend configuration features Cochran's patented gas blend switching.
