When you compare our tanks, note the following features:

• Our tank is 414 cu in water volume (74 cu ft air).  Always use the water volume to compare tank sizes, its the most reliable method.
• The Great White will fill a Marauder 63x from 2000 PSI up to 3000 PSI, Our Mid-size Tiger Shark 47x.  
• The Great White measures 6.9" Dia x 21 long (sans valve); weight = 12 pounds (sans valve) 
• The Tiger Shark measures 6.5" Dia x 19" long (sans valve); weight = 9 pounds  (sans valve)

• All of our tanks can be filled via a SCUBA Shop. (And a Paintball shop with Opt 2a).
• Our hoses are rated over 9,000 PSI Working pressure and almost 30,000 PSI burst (50% higher than most others)
• Our hoses have stainless steel strain-relief at each end and we've never had a hose burst (out of many thousands sold)

• Our Gauges have are a 50% larger dial area and are MUCH easier to read than others.  We use the best (USA Made by Wika) Stainless Steel, Glycerin-filled, Dual Scale, with the highest accuracy.  We also stock replacement gauges to upgrade other brands of tank valves.

Our TJ3 SLO-FLO valves make it much Easier & SAFER to SLOWLY fill your PCP Airgun:

• We designed our TJ3 DIN300 PCP Airgun valve SPECIFICALLY to fill PCP Airguns.
• Easier & SAFER to SLOWLY fill your PCP Airgun because EVERY TJ3 is calibrated for airflow by hand prior to ship. 
• Our 1-Way restrictor 
• We use a Marauder as a sample PCP Airgun, and adjust the flow to take about 5-10 second to fill it from 2000 PSI to 3000 PSI with the TJ3 valve WIDE OPEN. This is plenty of time for you to shut off the valve.  Open most other SCBA or DIN valves and the airgun would over-presssurise (and possibley be ruined) in a fraction of a second.  
•  Because of our 1-way restrictor, you can reverse fill our tanks quickly through the hose if you wish, such as via a Shoebox or Paintball store. Other use restrictors in the hose prevent filling through the hose. They act as a partial "Dead-Head" and give a false reading for the output gauge.

• We include the Stainless Steel Foster Quick Disconnect free, even in our basic package (no hidden charges).

 We offer 3 options (and 100% of our customer purchase these 3 options).

• Opt 1) 2nd Gauge - In addition to the large gauge, we offer a Patent Pending 2nd Gauge that constantly shows the pressure inside our tank

• Opt 2A) We put a Stainless Steel Female Foster on EACH end of the hose, and we provide a Male DIN300 with Stainless Steel Male Foster. This gives 2 benefits:
  •  No large wrench needed to carry with you to add, or remove, the hose from the tank. 
  • In addition to a SCUBA shop, the tank can now be filled at any store thaf fills paintball tanks.

• Opt 3) Full Armor - Protect your investment, Why let a large scratch void your tank?
  • Carry Handle
  • Feet - So the tank doesn't roll off the table (not metal, so they don't scratch)
  • Boot -  In addition to protecting the bottom of the tank, this allows the tank to stand up, and allows you to more easily view the main gauge while your filling your PCP Airgun or paintball tank.
  • Tank Protector - Further protection for your investment.
