Which SPG?

[kaliban]

I'm looking at two SPG's at COVCI, each is brass and each is $90. One is called Alpha Brass SPG, the other is called Mini Single Brass Pressure Gauge. http://www.covci.com/catalog/index.php?cPath=32

Any idea which is better, or is there another recommendation? Is $90 about right?

Thanks for the help!

I can't really see the difference between the two. I bought the OMS guage at LeisurePro. If you go OMS, don't get the larger SPG because it's NOT graduated in 100PSI increments (mine is 250). The smaller SPG DOES have 100psi increments

They look quite similar to the LP offerings but it is hard to tell with the photos Chris has on there. Email him and ask if they both have 100 psi markings. Be prepared to wait for an answer... I understand he is *outoftown* at present.

Personally I would go for the bigger one if it has the 100 psi markings... unless you are going to be putting it on a deco bottle reg.

I'd buy the OMS or Halcyon guages. They come ready to go without all the pesky rubber booting.

For $10 I'd nail another rubber boot to the tree out back.

Now I know what to do with those boots

I live in a highrise condo and they always look at me funny when I take the elevator down to hammer rubber boots into the grounds trees otherwise I'd be first in line.

since we are on a subject of SPG... what is your view on those small mini-gauges that screw-in directly to the HP port of the first stage. I mean, for use on a stage bottle. I know they are horribly inaccurate (mine shows 2500psi when it's really 3000), but do we really need to see exactly how much gas is in bottle since most stages are timed on you bottom timer vs. using rules of 3rd etc as you would on a primary tank... At this logic, it would seem that you only need a rough idea of the pressure, and those mini-gauges do just that. Any opinions before I throw mine away and get a real gauge...

I got a cheap used one on ebay to use on my Argon tank.

I use Apek's brass SPG. I think Apeks also carries those small button SPGs that screw directly on the HP port... I too am curious on the DIR stand on these things... why they haven't been recommended or used by DIR.
