Air Gun Scuba Cylinders

The Scuba Doctor has 232 and 300 bar Faber steel scuba cylinders for charging your airgun, air rifle, pre-charged pneumatic (PCP) air rifle and paintball cylinders/tanks/bottles at the best prices available. We recommend you use a 300 bar steel cylinder as you'll get a lot more fills (it could be something like 3 times more). But check that your local dive shop can do scuba cylinder air fills to 300 bar as some only have compressors rated to 232 bar.

Using a 232 bar scuba cylinder to recharge a PCP air rifle to a target pressure of 180 bar should give you a reasonable number of fills. But if your air gun is being recharged to 220 bar, then a 232 bar scuba tank will give you very few fills. If a 300 bar scuba cylinder is used as the recharge air source then you will get plenty of fills in both cases.

300 bar Steel Cylinders

Midland Diving Equipment DIN Gun Charging AdapterWe have available 300 bar (4,350 psi) Faber steel scuba cylinders with 300 bar DIN valves in 3 litre, 5 litre, 7 litre and 12 litre capacity for charging air rifles. Most people use the 12 litre capacity 300 bar scuba cylinder. The 3, 5 and 7 litre cylinders are typically only used as a more portable solution where mobility counts. It's extremely rare to find 300 bar cylinders for sale second-hand.

The 300 bar scuba cylinders are usually connected to your air rifle using an adapter with a 300 bar male DIN fitting at one end and the fitting required for your air rifle cylinder at the other end. We do not supply these DIN 300 bar adapters. (We suggest you try Hermanns Sporting Guns.) These adapters can be used with scuba cylinders using a 300 bar DIN, 200 bar DIN, or DIN/K valve.

How many fills will you get from a 300 bar cylinder? Well, there are so many variables that we're not prepared to say. Other owners of the setup you're using should be able to answer this much better than we could.

232 bar Steel Cylinders

Midland Diving Equipment A-clamp Gun Charging AdapterWe have available 232 bar (3,365 psi) Faber steel tanks with DIN/K valves (232 bar DIN connection with the insert removed, and Yoke connection with the insert in place) in 3 litre, 5 litre, 7 litre, 9 litre, 10.5 litre, 12.2 litre, 15 litre and 18 litre capacity for charging air guns. If you're buying a 232 bar cylinder, we suggest the 12.2 litre capacity cylinder.

The 232 bar scuba cylinders are usually connected to your air gun/rifle cylinder using a Scuba Filling Yoke/A-Clamp/K-Valve Adapter for PCP Rifles with either a 1/8" BSPP thread or a Female Foster Connection. We do not supply these adapters. (We suggest you try Hermanns Sporting Guns.) These adapters can't be used safely with 300 bar scuba cylinders.

Tech Tips

Refilling the scuba cylinder is best done at a dive shop where the compressed air provided should be completely free of moisture and other contaminants. The compressed air that you pump your car tyres up with is not clean or dry enough for a PCP air rifle, and the pressure wouldn't be high enough anyway, e.g. 150 psi (10 bar) when you need 3,000+ psi (200+ bar).

When charging the rifle, open the scuba cylinder valve very slowly. This will allow the air to pass along the filling hose, open the inlet valve and fill the reservoir. Only partially opening the cylinder valve will let you control the air flow. A slow fill is a good fill. Opening and closing the scuba cylinder valve quickly will give a false reading of how much air is in the gun, it can also damage the rifle.

WARNING: Never use anything other than divers' quality compressed air to recharge your PCP air rifle/gun. Using gasses other than clean, dry, breathing quality compressed air can be highly dangerous and will usually invalidate air rifle warranties.

Air rifles must never be filled to more than the manufacturers stated pressure, which is likely to be much lower than the pressure in the scuba cylinder. By exceeding the recommended pressure two things will happen. The first is that the power of the gun will drop significantly. It's a myth that the higher the pressure in the gun, the more power it produces. In fact, you normally find that maximum power is produced about 10 bar below the maximum recommended pressure on non regulated rifles, and a 20 bar overfill can reduce the power by 40%.

In order for scuba tanks to be refilled in an Australian dive shop they are required to be tested every year if they are used for diving. As a dive shop has no way to tell that you're using the cylinder exclusively out of the water, they will require the scuba cylinder to be in test before filling it.

We suggest you avoid aluminium scuba cylinders as most are only rated to 207 bar. Do not buy second-hand old aluminium cylinders (made of 6351 aluminium alloy, or pre 1995) as some have been known to explode and kill people. Plus you probably won't be able to get these old aluminium tanks tested, or filled at a dive shop.

A full scuba cylinder contains an enormous amount of energy. They are quite robust, however, you should treat them with great care.

We recommend you put a For Paintball Use Only cylinder sticker on scuba cylinders used to fill air gun and paintball cylinders.

Depth: 1 m (3.28 ft) to 3 m (9.84 ft)

Level: Open Water and beyond.

Banksia Point is an interesting diving and snorkelling site at Ricketts Point, Beaumaris facing south-west into Port Phillip. It's part of Ricketts Point Marine Sanctuary, a 115-hectare area located at Black Rock and Beaumaris, in north-eastern Port Phillip. Banksia Point is rarely dived or snorkelled, but can be very pleasant on a calm day.

Banksia Point is a great site for beginner snorkellers and night dive enthusiasts. It's so close to the city, thus very convenient for those living in Melbourne. Great for getting back in the water, a night dive after work, or just an excuse to get wet!

Diving and Snorkelling at Banksia Point

Most of the suggested path is close in with water depth up to around 2 metres. While the dive is shallow and close to shore, there is plenty of interesting marine life to keep you engaged.

MELWAY Ref: Page 86 B7

Parking: Park in Coronet Grove, Beaumaris, and carefully cross Beach Road. There is no beachside parking, so please be careful crossing Beach Road. Before gearing up check out the water. If you see lots of white water, head on home.

Warning: Always go with a buddy and carry a dive knife. Make sure you tow a dive buoy with dive flag.

Dive Entry: Take the steps from Beach Road, opposite Coronet Grove, down onto the beach. The entry and exit are from the beach out from the bottom of the steps.

Ideal Conditions: Banksia Point is best dived with offshore light northerly to south-easterly winds. Avoid diving with moderate to strong onshore southerly to north-westerly winds. Just before the high tide will give the clearest water. See WillyWeather (Ricketts Point) as a guide for the tide times and the height of the tide.

Ricketts Point Marine Sanctuary

This dive site is located within Ricketts Point Marine Sanctuary. There are actually a number of diving and snorkelling sites here including:

Ricketts Point Marine Sanctuary is on the north-east coast of Port Phillip and is approximately 20 km from Melbourne CBD. It abuts the Bayside City Council Foreshore Reserve from Table Rock Point in Beaumaris to Quiet Corner in Black Rock. It extends from the high water mark to approximately 450 m offshore.

Aboriginal tradition indicates that the sanctuary is part of Country of Boon Wurrung people.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
