Cochran EMC-20H Dive Computer

The EMC-20H is the simplest yes most sophisticated of the mixed gas dive computers on the market. The computers is easy to operate and understand, even for beginning tech divers. It is ready-to-use straight out of the box. Merely understand the large easy-to-read display and audible warnings. Cochran dive computers are the only dive computers authorized for use by the U.S. Navy and NATO.

The intelligence built into the EMC-20H manages everything else. It automatically, seamlessly, and constantly adapts to your personal diving style, water temperature, salt/fresh water, ascent rates, and altitude . Gas selection and switching is simpler than any other product on the market. Plan your dive -dive your plan. Set your unit up either for Open Circuit or Close Circuit or a combination of both. Gas switching is seamless and does not require any buttons to push. Plus the EMC-20 can never lock out if you miss a stop, it just plays catch up at the next stop.

The EMC-20 algorithm provides a perfect shape decompression and also will credit you for deeper stops instead of adding that long "tail" at the shallow stops.

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.
