Flying your unit manually .

Exactly my idea as well. Why would you spend the money on a controller if you are not going to use it?

Unless the electronics fail complete and you can't repair them for a bit. Then knowing how to fly the unit manually still allows you to dive.

On the Vision you have a hud and a buzzer, but you use the sound of the solenoid as an alarm bell ??? With a thick hood I can hardly hear the solenoid firing.

Yes, but everyone else can hear those damn buzzers. And they scare the fish away.

If your elecs were completly failed, you would still choose to dive the unit regadless??

If my elecs failed during a dive i would fly the unit home manualy adding 02 with my handset for P02 info or if the handset failed as well, i would even use the VR3 (4th cell) for sure to get me home, but i certanly would not go into the water knowing the elecs were shot at the start.

it either all works at the start of the dive or i dont go in, the manual add is a back up on a ECCR not an excuse to dive it knowing your main elecs are shagged to start with.

The PRISM works differently as the pO2 gauge is analog and doesn't require a power supply to operate. Same as on the MK15 and 15.5, the gauge is driven by the high output cells (16-22 mV) directly. The HUD, while usually referred to as the primary display, "only" shows that the setpoint is kept and the computer working, or warns when the setpoint is high, low, one or more cell(s) out of range, battery is low, or the computer hangs. In other words it's a warning system letting you know the status of your system.

Hence "failed electronics" translate into loosing the HUD and the solenoid, but not the ability to monitor the pO2 or manually inject gas.

No problem diving the unit without electronics, although you loose redundancy of two independent displays and pretty much are where mCCR divers with single displays are (stock COPIS Meg, Shearwater KISS without HUD, C2R Rebreather Monitor KISS without optional secondary display, Sub Sea Systems KISS etc) ... they all seem to have no problems either.

As i said.....a good back up for a failure, not a primary way to dive an ECCR.

I can run my car on flat tyres you know, it will still drive honsetly. But i would not choose to go to London and back from North Wales knowing they were flat at the start of the journey

Yes that might well be the case but gareths response wasn't aimed at hair splitting rather if you have a eccr and there is a problem with it why dive it ?
Thanks for the lesson though

More like driving your car to North Wales and back when the cruise control doesn't work.

But to each his own.
