People ask me all the time, "What rebreather are you diving, Jill?" The answer:
The Sentinel Expedition CCR from VR Technology is now available with the "Travel Frame" instead of the black box cover. Popularized in the Hollywood film "Sanctum," the Sentinel has also been approved by PADI for their "soon to launch" technical rebreather programs. Complete with a gaseous CO2 monitor, and Octocon data transmission, the unit leads the wave of new technology in rebreather diving.
