Q:

Picking a Scuba Tank

Hey ya’ll.

This is my first post here but i’ve been reading around here for a couple months. I just passed my PAL test in Vancouver BC so I am getting either a condor or a sumatra before christmas.

The local dive shop however has a huge anniversary sale and has a selection of tanks to buy brand new around 200 bucks this saturday. Before I go on saturday I just was wondering if there is anything specific I need to know about what I need. Other than it needs to fill to more than 3000 psi / 200 BAR.

Thanks 🙂

just wanted to thank you guys for the help (almost typed tank 😆 )

My tank will be here in two weeks. I got a 130 cf steel tank with a 3442 psi rating that the dive shop will fill to 3550 for 10 bucks a pop.

got it for 350 bucks, bout 50 bucks more than I wanted to spend but i figure 130 for 350 was worth it from the the 110 for 300. and if it wasn’t worth it don’t correct me 😛

The one I got comes with a pro touch valve. The guy showed me that its a K valve and a din valve in one. It’s a threaded hole that comes with a K valve threaded into it. When you un-thread the K valve the open space fits a din valve.

If any of that sounds like bull krap i’m just repeating what I was told.

Thanks for all the help guys.

You should be able to get a 3500psi tank for about that price. Mine is a steel 3500 psi that is normally filled to 4000psi. Steel tanks are safer to over fill cause they don’t stretch as much as aluminum. Aluminum might be lighter, but the extra psi will fill your gun a bunch. Do not get a 3000psi tank as the gun fills to that. Every fill after the first fill will be less then max and going south.

Other than a K valve, which I assume is what comes with the lower power ones, what else could it come with. Would the airforce fill valve only work with a k valve?

Thanks btw again guys for getting all this info answered so fast 🙂

If it doesn’t have a “k” valve, it will have a “din” valve which is threaded instead of the clamp/oring arrangement. You can get an adapter to go from DIN to K so that you can still use the AF fill yolk.

here’s a link to the adapter you would need.

Yeah, it looks like he is headeed for a lower pressure tank that will use a K valve.

Hey guys help me out here in case i’m wrong. He needs the “K” valve tank right? NOT the other one?

I would recommend either the 3442psi steel tanks or if your budget can accomodate it, get a carbon wrapped 4500psi 88cf tank

thanks steve thats a really handy calculator. My budget for the tank is pretty tight though so i’ll probly end up with steel. The place i’m going to on saturday has a couple different new steel tanks for around 200 bucks. Normally around 350 – 400 so thats what has me buying the tank before the gun 😛

PS: Abandon all hope ye who enter here 😆

Ya i’ll only be filling there as they are between work and home. No where else even close. Thanks for the really fast reply 🙂

So other than getting the biggest tank possible theres no specific things i have to watch out for. This will be my first pcp and i’d hate to get a tank and realise that it won’t work for some reaon 😛

Thanks for the welcome to 🙂 This site is great. I watch the hunting threads every day.

Find out how much they can fill to and buy a tank with that capacity if you’ll only be filling there. Or if they are willing to deal buy two tanks and fill from one and top off from the other. btw welcome.
