Hey check this out.....not to bad for someone that wants to get into the sport.... 150$ its got atleast a year maybe 2 left with adapter..

There are plenty of relatively fresh used tanks out there. By way of example, here's a new 2008 4500psi SCBA for @265 shipped.I think that is a good buy, they got at least 8 years of use left... ;D

You can pick up a fill rig from a number of suppliers including MAC1, Air Tanks for Sale, and eBay.
Always check the specs and ask all questions before buying anything online, and make sure you can find a local fill before picking up a tank.
I'm getting a little tired of the pump. What is the best economical set up to fill my Discovery? Where is the best place to get this stuff? I have a scuba shop about 2 miles away but not sure if that is the way to go or not. I know I can't afford 700 bucks for a tank for sure.
thanks
I don't know if it's all around the country but around here you can't get a scuba tank filled without scuba certification. In other words you have to have taken and passed the dive classes to be a certified diver. Maybe not all over but check it out first.Here in Mississippi, they just mark it down as AIR and Not for Diving... not sure of the exact wording! They always ask me if i have a certification, but you only need that if you use the tank for diving. So, check and make sure that if you only used it for AIR and Not Diving they may be able to fill it or they may not no they can do that. Each state probable has its own regulations!
I got two used 71 cf SCBA tanks on ebay for $270 with 5 years left on them . And if you look around online you can find the parts to build the adapters for less than half what the air gun shops are getting . JUST MAKE SURE YOU CHECK THE PRESSURE SPECS !!!!! I went with safety and got 6000 psi rated fittings . My SCBA to SCUBA adapter cost me $54 and 5 mins the tape and assemble . The fill shop wanted $150 for the same thing
Dawg11,
Where did you find the fittings online? Any links? Much appreciated if so!
If you are just filling the disco then save your money and dont buy a 4500 psi tank you wont need it. Just find a good used scuba tank and use that. You get plenty of fills in a disco and it has no shelf life if you do not damage it unlike carbon fiber tanks.

I started with a Disco and pump. Found SCUBA tank on Craigslist for $60 - needed hydro. SCUBA shop fills it for me $60 for 12 fills. Thank is marked "not for SCUBA" and they're happy. I bought a Ninja fill station and fill line off Amazon.
I still use this with my Marauder, which I usually fill to 2200psi. I also just bought a QB79 + 13ci Ninja tank - also fill to about 2200psi. This all works well for me, although on occasion I start thinking about setting up a cascade.
Do some research on aluminum SCUBA tanks before you buy. I forget the specifics, but tanks manufactured before date 'x' were of a different alloy that was/is prone to failure. SCUBA shops won't fill these - and yes, they can explode. Find out what the markings mean and check them before you buy.
I'd like to have a high pressure SCUBA tank - these can be filled to 3400psi or there abouts - then I'd fill the Marauder and QB to more like 3000psi.
Anyway, as long as you can get SCUBA filled, it's very serviceable for use with a Disco.

Aluminum scuba tanks manufactured after 1989 are still serviceable.

As a PSA, here's one link to info on SLC failures in aluminum tanks.

Quick story - Luxfer tanks made 1989 and after should not be a concern.

yes with a 4000psi fill. You would get more fills if you were able to fill the 66cf bottle to 4500.

Yea, I took you guys advice and got a 2008 model 60 min tank...Took it down to Carolina Carbonics in Greensboro yesterday To have it hydro'd and filled... JR and his wife are good people... They're a welding outfit so, I was surrounded by NITROGEN TANKS 8) ....I can see moving towards nitrogen in the future...I just have to get the right adapters for it....But thanks for the ebay tip, it worked out good for me
My only statement will be this. Carbon fiber tanks are good for 15 years, and only 15 years. I am disappointed that someone would knowingly tell another that a tank that is 14.5 years old, will be good for another 5 years, just because they did a recent hydro. It ain't so. Please read DOT special permit 10915 Section 7, paragraph C1. Bottom line, 15 years.+1
Here is the link to it:
https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=dot%20special%20permit%2010915 (https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=dot%20special%20permit%2010915)
You can't get a tank hydro'd on the 14th year 364th day, and get another 5 years out of it, or you'd be getting a 20 year (minus one day) tank. Even the mods from thsi forum will say the same as I saw them post similar recenlty.
I just don't want to see a bunch of guys getting steamed up after Jan 2016 when their dates run out.
Please don't bring up the subject, "They are still good if you have a compressor", etc. Not my intent to discuss nor debate. I'm talking legally, and for the 95% those of us that will fill at a Firehouse, SCUBA or Paintball Store, they won't fill them after 15 years (unless they just happen to not notice it has expired).
Best to all of you.
"Cylinders are also inspected at the appropriate three- or five-year test interval by
SCBA Cylinder Life-Extension Study, Final Report (August 2012) 2-2
certified testers prior to hydrostatic testing. About half of all visual inspection failures observed
are due to wear or damage experienced from exposure to knocks and abrasion during frequent
firefighting drills on Navy ships. The other major category of visual inspection failures consists
of those induced by hydrostatic testing—including cylinder stem thread galling due to improper
removal and reinstallation of the cylinder valve fitting, and to interior cylinder surface contamination
or corrosion caused by improper drying of the cylinders after hydrostatic testing.
Hydrostatic testing of the cylinders is accomplished by removing the valve from the cylinder,
threading on a test connection, filling the cylinder with water, pressurizing the cylinder to fivethirds
(5/3) of service pressure, and measuring cylinder expansion. Based on findings regarding
testing-induced failures and the high hydrostatic testing false-positive rate, it is likely that more
cylinders are damaged by the hydrostatic testing process than by service handling and usage."
?? please , I called the US wt/measure office and the NAFTA book people # are on the internet and you can get them from your fed, rep's office. From both office's The us standard is 15 years on HPA tanks, Same tanks in the EU are 30 years. , they could not say why. They have only had one documented fail at a fire dept. when a firefighter left his tank setting in paint solvent for 4 days in back of PU solvent spilled. Carbon fiber tank., then filled it to 4500 and put it in the truck. During that week it failed. I do not know what would cause a modern tank fail if made of steel or alum. ??? Any thoughts!!!

SCBA Cylinder Life-Extension Study, Final Report (A
ugust 2012)
The U.S. Department of Transportation (DOT) in the
Code of Federal Regulation (CFR) 49,
Section 180.205 mandates maintenance requirements f
or SCBA cylinders. Glass fiber-reinforced
plastic (GFRP) and carbon fiber-reinforced plastic
(CFRP) SCBA cylinder maintenance
requirements were established in the early 1990s ba
sed on cylinder manufacturer input. At that
time, there was extensive experience with aluminum-
alloy tanks but very little knowledge of the
long-term durability and strength characteristics o
f fiberglass or carbon fiber. A lower limit on the
service life of composite-wrapped cylinders was est
ablished at 15 years based on limited studies on
the durability of fiberglass observed in testing fo
r NASA aerospace applications. The 15-year
cylinder life is also linked to cylinder cycle test
ing (fill-and-empty cycles) at the time of
manufacture, when two percent (2%) of all cylinders
manufactured are cycled 10,000 times
(corresponding to about one cycle per working day f
or 40 years), then subjected to a number of
strength tests. Cylinder manufacturers submitted th
at this testing established a threshold level of
acceptable safety that can be reasonably expected o
ver a 15-year service life (regardless of the
working gas).
