FS - Aeris USB Computer Interface for ATMOS 2 (should work for ATMOS elite and Atmos ai as well). Used but it great condition. My Atmos 2 died and I have decided to invest in a different computer. So, I no longer have a need for this cable. Software can be downloaded from the DiveAeris website (under Software Support). Visit DiveAeris for more specific information on USB cable. $43 shipped anywhere in continental US. PM if you have any questions. I accept PayPal.
