Orca Edge, a Common card

The card carries these facts from its Wikipedia article.

• The Orca Edge was an early example of a dive computer that ran a real time algorithm.
• Designed by Craig Barshinger, Karl E. Huggins and Paul Heinmiller, the Edge did not display a decompression plan, but instead showed the decompression ceiling or the so-called "safe-ascent-depth" and a graphic display of calculated tissue gas loadings.
• A drawback was that if the diver was faced by a ceiling, he did not know how long he would have to decompress.
