What to do? Scuba tank or what

[markT]

My older AL scuba tank is out of date.

Now what should I do? I think my choices are buy a used AL tank.

or New carbon tank.

I only have one pcp that can hold 230 bar. The others are only rated for 200 bar.

The guy at the scuba shop said he can only charge an AL tank to 3100 psi.( 213 bar) -8% of full fill, if my math is correct..

I don't shoot that much only pest control. Never target shoot. Never tether and never will.

Any suggestions?

As far as I know, aluminum SCUBA tanks can be used as long as they pass hydro and visual, no other mandatory retirement date. If the tank meets your needs, spend the $50 for hydro test and use it.

There are lots of inexpensive 4500 psi tanks on Ebay.

As mobilemail suggested, see if you can a find a place to get your tank hydro tested-mine cost me $40 each to have the test done. The guy who did mine has retired though and no one local is doing hydros that I know of. If you find a facility that does the testing they may also be a good source for used scuba tanks-I got two from my local guy. The closer the better as shipping will hurt!

PS-If all else fails it sounds like a hand pump would work for you, especially if you just top off after a pesting session.

Regarding the 4500 Psi tanks on ebay. What do I need to look for?

i.e. mfg date cubi inches. etc.. how long are these tanks good for. If I had one charged to 4500 psi that would last for yrs.

I assume these will fit my current set up..

Thanks for all the replies.

First, find out how much PSI or BAR your scuba shop's compressor could fill up to. You'll then know whether it's worth it to get a SCBA/CF tank. I say it's worth upgrading to a larger capacity tank in terms of air pressure. You could always have the advantage in case a new dive shop that has a larger capacity compressor opens up near your area or your current dive shop upgrades their compressor or if you decide to purchase one yourself. It's just a matter of having the proper connections/adapters hooked up to your tank. If your dive shop's compressor could only fill tanks up to 3500 PSI, they could still fill a SCBA/CF tank to that pressure. Another option besides a CF tank is to get a steel SCUBA tank which most are rated for 3442 PSI/237 BAR. Just request that they fill or top off the steel tank to that pressure after it cools off.

Buy a compressor and never pay for AIR again! And you'll save gasoline too!

Compressor is both the short and long term answer!

You could even try one of the new gun charging units. Less money. QUALITY?

I don't think I want a compressor.. I've got enough stuff to keep up with. I would think that a SCUBA shop would provide very clean and dry air.. I'm going to hit the local shop and see if they have a used tank or see what it will take to get my current tank up to "code."

Went by the local SCUBA shop and my AL tank has to be "Hydro'ed." ( good for 5 yrs)

$60 total for the test and fill.

Then its $27 per year for "visual."

$7 per fill to 3200-3300 psi.

I guess he saw me coming..

 

[scubajeeper]

That is about the going rate for those services. Think about it, you are getting a hydro, visual and a fill for $60. Otherwise you have a totally useless tank because no scuba shop is going to fill it without a current hydro and visual.

Are all the compressors electric? I am somewhat new to all this and haven’t been around many
