Shearwater

seaturtle · 21st May 2006, 21:32

I'm having a problem with my #2 sensor reading on the handset.
It reads .00. Changed the sensor calibrated and the same thing. Anyone experience this problem? It's on a Meg.
Thanks in advance, Chuck.

Give Leon a call and don't dive on the unit. I saw this happen a few weeks ago on a friends MEG. I think this is the failure mode when they fail, the other cells will follow. Hopefully Bruce will also see this and give us some answers?
I have one also and have been waiting to see if it keeps running?

Hey buddy,

I had the same problem but my Meg has APECS 2 electronics.
I sent back to ISC and was just the sensor harness. Could be the same problem.
Cheers,

Hi Chuck.

I had the very same problem on _your_ unit (before you bought it). It first showed up on a dive where I would get wildly different PO2 readings (0.0 PO2 up to 1.2 - the setpoint). I sent it back to Leon (the original owner was out of the country). Steve S. noted some corrosion with the molex connector on the #2 sensor. He wanted to replace the electronics with APECs 2. The original owner wanted to keep the Shearwater & have it fixed.

Supposedly, it was fixed, but I think this might be an issue with that head if it is recurring...

Feel free to contact me if you have any other questions about it.

Hi Tim,
Thanks for the info. Yeah, I spoke with the original owner today and he told me about it being sent back for this. I hope its not the head, I really like the Shearwater.

I know your unit. Once it was calibrated it held steady. However, it did some interesting things beforehand. I agree - the Shearwater is a wonderful unit. My particular head has been very, very reliable. But, I do count on my electronics bagging out at some point.

Chuck,

Maybe it is just the wiring, that would be the least painful repair.

I second what Ken says though - with the Shearwater no longer being supported by ISC, it will need to be replaced with something eventually. That's too bad really, as the shearwater electronics are really nice.

With APECS 3 still vaporware and APECS 2 having no integrated deco, that only leaves the Hammerhead.

Whatever happens, I hope it's not too painful for you.

Not unless it's a software problem (that Bruce might be able to fix) or a hardware problem with the potted part of the electronics, am I correct?

How does ISC handle Shearwater replacements? That upgrade over the APECS cost quite some extra money, does ISC refund that as they should?

I haven't spoken with Bruce about it, but if you go to Leon with a Shearwater problem, He'll tell you to "upgrade" to APECS 2. I was told by Steve at ISC that when any Shearwater comes in for service on electronics, ISC will swap it out to APECS (after conversations with the owner, of course)

When this was discussed with the unit in question, the electronics replacement would have been done at a substantial discount from full price. In this case, the owner said "I paid for shearwater, I want shearwater..." and Leon and Steve set about fixing the problem. As mentioned above, corrosion on the molex connector was identified as the culprit. It appears that this wasn't the full extent of the issue.

The previous owner of this unit did speak with Bruce. I did not participate in that conversation, but my undestanding was that Bruce sent the owner back to Leon as it was a hardware issue rather than a software issue.

In the end, Shearwater on the meg is unsupported electronics. If something goes wrong with it, you'll end up replacing it with something else.
