Out of air! Wireless pod

[Steelyeyes]

You don't see any use in having an SPG? Redundancy is always nice and considered a must depending on the type of diving you are doing. You have listed yourself as a solo diver so you should recognize the importance of redundancy. I have seen air integrated computers fail due to electronic problems as well as dead batteries. Three weeks ago I was out on a boat and saw a guy lose the battery cap to his transmitter. I have never seen a SPG fail.

Maybe you are being sarcastic. Hard to tell.

SPGs fail too. They're just a bourdon tube pressure gauge and like anything they can fail. I have one transmitter, two computers synched to it and an SPG when I travel far from home.I also have a spare transmitter in my camera box. I might not bring the backup computer when I dive locally because not diving for a day due to a computer failure wouldn't be a big waste of money.

On the boat we figure out what happened. Lesson to everyone who uses a wireless connection for gas supply. The crew had inadvertently put my reg (and pod) on her BCD and hers on mine. She had trouble with sync before the dive, remember? So we synced her computer to MY pod which unbeknownst to us was on HER tank. I could still read supply because when I checked, I was right next to her rig which had MY pod and I was still synced to it. Problem was, her pod was on my BCD synced to nobody. So when we took the plunge we were both synced to MY pod which was on HER tank. I was reading her gas all along thinking it was mine.

Won't do that again!

This is why people should set up their own gear.

I've been using analog SPG's for <40 years I've never had one fail during a dive so no I don't see a need for redundancy in that area. Now if I had a quirky, unreliable, AI that would be different. I figure why spend the money for AI and have to carry 2 SPGs for each tank on my independent doubles setup when I already have analog SPGs. It was sarcasm @WinfieldVC. you are correct.

I've had two SPGs fail over 2 years. I'm surprised I haven't been struck by lightning, as the probability of those failures is so incredibly low.

I've had two gear failures during my time diving. Both were SPG related (one detonated when I turned on a tank, the other just rapidly drained out through a blown spindle o-ring, both were on rental gear)

Analog SPG fails differently though.

I've never seen one give false readings, it'll just stay stuck at some pressure level, or just show zero.

If you are monitoring your air levels, if you dont see it going down, you should know what that means.

I'd never use wireless myself, ever...

I've lost a number of SPGs, but just those mini button ones. They either blow up, or stick full.
Never have lost a 1.5in+ brass and Glass SPG. (and most of my dives are technical dives)

Of course they fail. Did the failure take place during a dive? I had one fail when I turned the air on, not diving. The latest one I failed, it was clear that water had gotten inside, it was still working but I replaced it with one from eBay. I was specific in my post of failures during a dive. IMO a failure anywhere else doesn't count.

@WinfieldNC for your edification, I dive my double hose sans SPG, I have this device called a watch. I note the time I start I usually come out with between 400-700PSI. <2000 dives learns ya.

Did the failure take place during a dive? .

Yes they did. I was fortunately diving sidemount, so I couldn't understand how my left side was lighter than my right, despite having a higher pressure value. Then I noticed the water inside.

Edit: correction: one died during a dive.

@DrMack Why don't you use a larger tank? Many dive operations have 100CF available.

Did the failure take place during a dive?

The 2nd one did. The first was gearing up, getting ready to hop in the pool during my OW training.
