Shearwater on the PRISM

Might be another idea.

Yes, and it is the only option available now, or whenever JM will be able to fit the hardware.
Sensible idea actually, as the HH might well work with the SMS202 sensors and
hence offer the option to use either the stock secondary or the HH secondary.
It is my understanding that MK with HH could be used with either.

Chris, didn't realize you wanted to change the entire controller, thought you were just
looking for a digital secondary. What did Bruce suggest as a secondary display?
The HUD as was used with the Megalodon?
The pO2 gauge as used with the Shadow Pack III?
Or keeping the SMI secondary?

then you would need to carry both the analog and digital version for every time you want to check the battery or change/check set point. (not often I admit but...)

You don't actually need either the setpoint or battery functions.

Set the setpoint by counting the clicks (not that I've changed mine in the last 6 months). Verify on the bottom - the unit will hold what ever it's set at.

Low battery warning on primary - I've got a couple of dives on mine with the low battery warning flashing, no problems. And if it fails, who cares? Dive manually.

So these functions are not required - however I actually like the analog guage just fine, and have no problem comparing cell readings.

Hi Stefan
Noo I am only after the Shearwater Handset to be used as the secondary, I am not going to swap out the whole controller.

For those that are raving about the analouge mine went belly up after 10 hours of diving and started reading .2 instead of 0 when disconnected from and connected to the unit, stuffing up all the readings. I sent it back to SMI and after having it for a month they said the Calibration weight had fallen off the needle

So I asked them to send it back, as they would not replace it under warranty saying it had been bashed hard and that was the cause of the weight falling off.

So I finally get it back after 2 months and take it for a few dives. And then as if by magic after the second dive the compensation weight must have re-attached itself to the needle cause it started reading 0 again.

Now I am more inclined to trust a nice box of electrics instead of a little poxy needle. And besides your Primary is electronics as well and that has to fail first before you go to your secondary be it analouge or digital each to their own.

Cheers

Uh, I hope you called or email'd them to let them know your findings. I'd of had some real prime words for them. Especially when they mis diagnose the problem and don't want to cover it under warranty...

What a joke of a company....

Interesting. A similar thing happened to mine. I bashed it whilst it was disconnected from the unit. However, I just left mine alone for a few days and when I went back it had sorted itself out. No problems since (18 months of diving).

The fragility of the secondary worries me a little, although I have (accidently) smacked it around quite a lot rib diving, without problems. I try to minimise the time it is disconnected, and treat it with kid gloves while it is disconnected.

What I want is a robust digital secondary that I can throw in my gear bag so that if the analogue secondary goes tits-up on a diving trip I have a backup to use.

Pete Readey inveted the self-repairing secondary.

Exactly my thoughts.

Yep working on this, the Shearwater handset would be nice, its very Exxy though.

I hope to have a small 3 cell digital secondary for the PRISM with all going well in the next couple of months. It should also be cheaper than the SMI analouge secondary. It will be identical to the one being used ColKans new Eagle SCR/MCCR/ECCR.

Hi fellas, just wondering why anybody would need to disconect the 2ndry for any length of time? I keep mine on a sensor in btw dives/storage and attached all the time, except to clean the contacts, yearly. It says clearly in the manual that the movement needs to be under load to keep it from being jarred and broken. Also, I don't think it's a good idea to mess with those pressure fittings on the end of the cables any more than you have to... -Andy

Come on now mverick, this is a bit much. You're a smart guy, you know there's 2 sides to every story. The whole Prism/Oz story get's more and more complicated the more I hear. And I've heard it from both sides. Chris has every right to complain if he's had a bad experience. What I don't get is people who don't have a Prism and have no intention of buying one, complaining and ragging on the company. What's in it for you? No comprende... -Andy
