I think the image below covers it all really… VR Technology are offering a Free Triage Kit (a full set of assorted spares) and a NHeO3 dive computer free if you buy a Sentinel rebreather. Buy a Sentinel Expedition and not only do you still get the Triage Kit free, but you also get a VRx in-place of the NHeO3!
These both represent some pretty amazing savings.
