Pelagic Pressure Systems has had long history of developing decompression algorithms for safe diving. The principal designer of these algorithms is Dr. John E. Lewis, who has been with Pelagic for over 34 years. He is one of very few people in the world that have the knowledge to develop the algorithms that are used in dive computers.
Dr. Lewis earned his Ph.D. in Aeronautics and Applied Mathematics from the California Institute of Technology. He has been influential in the dive community, as the principal author of “The Recreational Diver’s Guide to Decompression Theory, Dive Tables, and Dive Computers” and as a member of the Underwater Hyperbaric Medical Society.
Dr. Lewis wrote the proprietary Pelagic Z+ (PZ+) algorithm employed in computers. The PZ+ algorithm is based on the Bühlmann ZHL-16C algorithm and is a favored recreational algorithm for the safety conscious diver.

Several brands of dive computers, including Aeris, Genesis, Oceanic, Sherwood, Tusa, and others are collectively known as Pelagic Systems dive computers. Aeris, Genesis, Oceanic, and Sherwood all sell their download cables separately from the dive computer. It has a USB port on one end, and a connector specific to your dive computer on the other. You will need to find the correct cable for your dive computer.
The connection between the cable and the dive computer is the "weakest link" for these computers. It's very easy to not have a proper connection, meaning that data does not transfer and the download fails. If you are having trouble downloading your dive computer, this is the first place you should check. Remember that some models can have the connector to the dive computer itself plug in upside-down! If it’s not working, double check this connection.
If you have a 3rd party cable to download your Pelagic computer, you must also have a kernel device driver from them for that cable, which provides a serial port for applications to use it.
