Does anyone know how many fills you get from a 40 and 80 cubic foot scuba tank on a maurader rufle. The local diving shop will sell me a new 80 cubic foot scuba tank rated at 300 p.s.i. and life time refiils for free. for $220.00 I will order the rifle soon but I am doing some fact finding first. I am not that thrilled at paying $500.00 for a shoe box compressor.

If you fill the tank more then 20 times, it start to pay off 120.00 for the tank, 100.00 for fills (or 20 fills at 5.00). And it is probably a 3000PSI tank.

The number of fills you will get with a scuba tank are very few. I'd be at the shop filling up 3-4 times a week!

Take it a step further... Buy a Show Box Compressor and never pay for another fill.. But the pay off would be longer.. hehe

Have not been to scuba shop in over a year now thanks to my Show Box Compressor.

Robert, the free fills portion of the deal is what makes it a good situation if you are close enough to the dive shop.  There is one problem though.  If I am reading your post correctly, it will be a 3000psi scuba tank.  The problem is that the Mrod fills to 3000 so theoretically you will only get one complete fill of the rifle before your tank drops below 3000psi.  Then each succeeding fill will be less and less.  Lots of folks only fill their Mrods to 2700-2800 or so which would give you a little headroom but not much.  Believe me when I say that when you start shooting the Mrod you will want as much extra psi in your fill tank as possible to allow you to shoot more between tank fillups.

I would check out the possibility of a higher psi tank before getting the 3000psi.  Let us know what you decide.

Agreed with Joe, if shoebox is out.
You could also get a hand pump to top off your gun as the tank lowers(and as a back-up), until you get back to the shop to refill. The Marauder has a 215cc reservoir, so use that in a fill calculator program in the library to get an idea of how many fills it would be worth.

I want to get a shoebox compressor.. it's on my list of toys to get. Can't go wrong with it!

Like Joe said using a 3000 PSI tank for a 3000 PSI will give you only one complete fill. You could tune your MRod for a 2500 PSI fill and get several. If your punching papaer the 2500 PSI would be fine but if you are going to hunt and go after anything larger than grey squirrels and crows you would want to use the 3000 PSI fill for more power. Getting started with a 4500 PSI carbon fiber tank may save you money in the look run

Robert, I've only been at the pcp business for about a month now.  I started out with an 80 cubic foot aluminum dive tank for filling...with a max of 3000, over filled to 3200.  Worked fine for about 7 fillups, then it didn't have enough pressure though it still had 2900 psi...couldn't fill the gun to 3000...

Now, I'm using a steel low pressure dive tank 108 cubic feet, converted to high pressure and filled to 3500 psi which according to them makes it 150 cubic feet.  The tank is safe to 4000, but just trying different things...  If filled to 4000 psi, they tell me it will equal 180 cubic feet...

I've ran some 300 shots off of this tank so far with no drop in fill power that I can tell.  I fill my gun anywhere from 2800 to the max of 3000 according to the gage...usually 28/2900...

I'm a happy camper with this setup so far and really love that Marauder...oh yeah, if it matters, it's in 22 caliber...amazing power and everyone says the 25 is even more killer...

Good luck with it, and keep us posted!

The more air you can afford the better but I went the poor mans way and got a used scuba tank and
tuned the mrod for a lower psi fill but I had to get a chrony so how much did I really save? but I had
allot of fun tuning them. I have the .177 set for 2500psi fills and I get 20+ fills and the .22 set for
2000psi fills and I get allot more fills. I do not get max power out of the .22 but it is still good enough
for my small back yard. the .177 still makes good power shooting in the mid 900's
