Deco tank SPG ** POLL **

[Mike Edmonston]

On all of my stage regulators, I use those small screw-in spg's that are the equilant size of approx. 10 dimes stacked up and thread right into any high prossure slot on the 1st Stage. I rarely ever have to look at the spg, but it does come in handy from time to time - inexpensive, non-obtrussive and handy.

I agree, those work really well. In fact at the shop today we were 50/50. half of us don't use spg's and half use small or "button" spg's. The conversation was migrated into more of a preference for having a gauge, but not really needed if pre dive checks were performed.

I need a larger one so I can see it. It's an easy check. You are not going to know if you are losing gas because of a leak without it.

So Mike, let me ask you.... what is the point of this thread? You normally seem pretty level headed, but answering your own poll to discuss the necessity for a gauge on an O2 bottle seems strange to me.

What does not having one get you? No spindle orings. Big whoop. Pretty weird trade for a lack of information about your gas quantity. And having gas/tank specific regs.

Maybe he needs to save his cash.

Actually I only answered it so that I could see the results. I couldn't get to the poll without actually voting. Maybe there is a way to view the poll without voting on it? I don't know.

I am not condoning or condemning the use of a gauge. Nor am I trying to convert anyone in any way. I am just curious as to who uses spg's and who doesn't. and moreso the reason why they do or why they don't. I have explained my reasoning in an earlier post, but it is by no means the only way to do it.

I just have a button spg for the first stage. Always check my pressure before jumping in the water....unlike those spare air testimonials.....

In my best JeffG impersonation..........

Yes you will, think about it.

Good point, but I check my gas before I get to the water and tie off the tank, then I check to make sure the tank valve is shut. If the gas goes away when I was in the cave, what difference does it make if it had a gauge or not? I still have to deco on backgas.

Not if its on leash behind you. Of course a gauge doesn't help much there either...

But it is possible to lose gas and not know until some later portion of the dive. Or without a gauge to not know *** happened.
