So back to topic. Is the VR3 the best backup? How about the HS Explorer? I see they have a model with O2 input now? Are there any others? More important do these do the job we are asking them to do? Could they be better and if so how? Do they allow for a setpoint change or does that matter if they are reading o2 via sensor?
Yes the VR3 allows two set points, you can change them underwater anyway.
I have mine set to 0.7 and 1.25, if i decide I want to run my deco at 1.5 I can raise it.
Can't say alot about the explorer other than I don't like the buttons.
