Dive Rite has chosen to use Shearwater electronics to control and monitor the Optima CM. The controller is a DiveCAN Petrel 3 handset. The controller allows diver control of the PPO2 setpoint and PPO monitoring of oxygen sensors 1, 2, and 3C. It also functions as a full featured dive computer displaying depth, dive time, decompression information, and other important dive information.
It is recommended to use a second standalone dive computer with decompression information as a backup in addition to the controller.
For detailed information on the DiveCAN Petrel controller, please see the Shearwater Petrel DiveCAN Rebreather Controller Model Operations Manual.
Dive Rite now offers an optional Shearwater NERD 2 controller for the O2ptima CM which allows full set-point control without a Petrel 3 controller. Contact Dive Rite for more information.
