The Back-Packable 17 Cu Ft "GUPPY". 

 Now you can very easily carry on your belt or backpack a complete Air Tank and Hose Assembly.  In addition, our tanks waste less air than other tanks, since the gauge, bleeder, etc. are all integral to the valve, instead of hanging on as an assembly.

The smaller tank is my very portable 17 Cu Ft 4500 PSI AIR TANK called the "Guppy". They weigh Only 3.3 Lbs & Measure under 11.5" long by 4.5" diameter (sans valve). These are ideal for those that want to backpack a tank when hunting or if you own a Shoebox compressor. If you have an FX Rifle with 180 CC Air Tube, Fill to 3000 PSI, shoot to 2000, refill to 3000, you would get about 13 fills with this tiny tank. If you have a Marauder and fill to 3000 PSI and refill to 2000, you would get about 11 refills. Please see description below.  The Guppy is perfect for use with the Shoebox compressor.  You'll have a 4500 tank that is fast to air up and still gives a number of fills to your airgun. The Guppy comes in 2 versions. I strongly suggest Version 2.

Guppy with DIN300 valve and complete Hose Assembly = $389.  Nicest you will ever see nothing extra needed.  Includes EVERYTHING you need to fill your airgun in the field: Tank, with LARGE Stainless Steel 2" Glycerin-Filled Gauge with BAR & PSI Scale (so no guessing about the PSI you are putting in your tank), MicroBore Hose with strain relief on each end to help prevent kinking. Everything you need to fill a Marauder, from tank to hose, gauge, bleeder, and female quick disconnect. 

Note: All of my Tanks with Hose Assembly can be filled directly from a Shoebox Compressor, no extras needed. Here it is shown with a Shoebox Compressor.

 

 

 

 

Here are a couple extras you might want to consider

Guppy/Great White with DIN300 valves are ready to go as is, and loaded to the max with upgrades, but there are now 2 options available.

 

Option #1 Second Gauge that constantly shows pressure inside the Guppy or Great White.  All Guppy come with the Highest Quality U.S. Made 2" Stainless Steel Glycerin-Filled Gauge that show the pressure in the hose that is filling your airgun.  This second gauge will allow you to know the pressure remaining in your Guppy.  (Normally $49, on special for $29 when purchased with airtank AND you mention the Forum)

(See pictures below) 2.0" standard Gauge (Left) .  Second optional 1.5" to show pressure remaining in Guppy  (Middle and Right)

 

Option #2 Stainless Steel Handtight DIN300. These are a very nice DIN300 Handtight fitting that replaces the wrench tight fitting the connects the hose to the Guppy or Great White (I am not referring to the other side of the hose with the Stainless Steel Female Quick Disconnect that fills your airgun).  This is convenient when filling your tank at the SCUBA shop so that you don't need a wrench to remove the hose.  This is a finely crafted and machined Stainless Steel DIN300 that looks like a piece of jewelry. It is the finishing touch if  you want the ultimate system.  (Normally $59, on special for $39 when purchased with airtank AND you mention the Forum)
