Which Size Steel Scuba Cylinder Is Right For You?

Divers in cooler temperate waters most commonly use the following three Faber steel tank sizes:

Faber 10.5 Litre (85 cubic foot), 232 bar — This smaller cylinder size is preferred by many women because it's lighter and easier to handle. If you are a diver with a very good surface air consumption rate, as many women are, then this cylinder has enough air capacity for most dives. A pair of these steel tanks is also popular with sidemount divers, and women technical divers.

Faber Standard 12.2 Litre (100 cubic foot), 232 bar — This standard size, 178 mm (7 inch) diameter, cylinder size is used by the vast majority of divers. A pair of these cylinders is also the most common choice for technical divers.

Faber Standard 15.0 Litre (125 cubic foot), 232 bar — This larger size, 204 mm (8 inch), cylinder size is the choice of divers with a poor surface air consumption rate. However, it's larger size and weight makes it awkward for many divers to use.

Faber 3 Litre (25 cubic foot), 232 bar, 100 mm (3.9 inch) diameter, are the popular choice of rebreather divers.

Low and High Pressure Steel Scuba Diving Cylinders

Faber Low-Pressure Steel — 232 bar — Lighter on land than standard aluminium scuba cylinders, these Faber 232 bar steel cylinders feature a higher working pressure than most aluminium cylinders, thus delivery a larger gas capacity for the same internal volume. The 232 bar Faber cylinders come equipped with a DIN/K type valve that easily converts back and forth depending on the type of First-Stage Regulator to be used in conjunction with the cylinder increasing the versatility of the tank. When diving with these cylinders less weight is needed, making them perfect for divers that use drysuits, or wetsuit divers in cold/temperate waters. The Faber steel cylinders are popular for cave diving and have a strong following among technical divers everywhere. The average working pressure is 232 bar.

Faber High-Pressure Steel — 300 bar — Much heavier than standard aluminium and steel scuba cylinders, these Faber 300 bar steel cylinders use much higher working pressure to provide a huge gas capacity in a small size. Like their low-pressure steel cousins, less weight is needed with these cylinders. A favourite with wreck divers, the average working pressure is 300 bar.

Faber is the leading manufacturer of steel scuba cylinders in the world and is the market leader in Europe and Australia where diving with steel cylinders is the norm. Faber's cylinders are manufactured from deep drawn 34CRMO4 Chromium Molybdenum steel plates to ANSI specifications. This process results in a light cylinder with the right buoyancy characteristics allowing the diver to reduce the amount of weight from their weight-belt. The interior of the cylinders are shot-blasted followed by their exclusive phosphatised coating which creates a perfectly cleaned internal surface, highly resistant to rust. The exterior of the cylinder is triple protected with zinc spraying, epoxy primer coat and polyurethane finish coat for durability.

The service life of a properly cared for modern steel scuba cylinder is widely considered to be 50 years or more. The service life of a properly cared for aluminium cylinder is more controversial. Most dive shops, including The Scuba Doctor, won't fill an aluminium tank manufactured before 1990.

The Scuba Doctor carries an extensive selection of Faber steel cylinder sizes starting with the 2 litre (16 cubic foot) all the way up to the 18 litre (150 cubic foot) cylinder. Faber cylinders are available in 8-inch, 7.25 and 7-inch diameters with working pressures of 232 bar and 300 bar.

All dive cylinders from The Scuba Doctor dive shop are visually inspected and shipped with a current hydrostatic date (except where indicated).

Eleutheria

Wreck Dive | Boat access

Wooden Hulk | Max Depth: 20 m (66 ft)

Do not dive near the Eleutheria without a permit. The shipwreck lies within a 250 metre radius protection zone for the City of Launceston. If you enter this zone severe penalties apply. Stay clear!

Level: Advanced Open Water and beyond.

The Eleutheria shipwreck lies near the City of Launceston shipwreck in Port Phillip. After trading around the world as a three-masted wooden barque, she was converted to powder hulk in 1862. The Eleutheria was later used as the base of operations for salvage attempts on the City of Launceston, during which she sank on 5 July 1866.

This gets interesting. The Eleutheria lies 157 metres, bearing 227°, south-west of the City of Launceston. The site of the City of Launceston is a historic shipwreck protected zone with a 250 metre radius from:
Latitude: 38° 4.610′ S (38.076829° S / 38° 4′ 36.58″ S)
Longitude: 144° 49.579′ E (144.826321° E / 144° 49′ 34.76″ E) .
As the Eleutheria lies within this protection zone, a permit from Heritage Victoria is required to dive the Eleutheria. Anchoring is prohibited.

The winter months offer the best visibility at the Eleutheria wreck, especially when the water temperature drops to around 10°C.

There is a great deal of the wreck exposed and a considerable number of objects throughout the site. Whilst the many iron knees and ships timbers are easy to identify, there are several large objects yet to be identified. There is a small steam engine or pump at the port bow, which is heavily encrusted.

A heavy wire cable lies across the wreck about amidships. This cable may be part of the salvage gear, or the remains of a scallop dredge cable.

Eleutheria Shipwreck History — Built in 1835

The Eleutheria was a three-masted wooden barque of 404 tons, built in 1835, launched on 23 January 1835, and completed on 24 January 1835, by Cuthbert Young & Son, at South Shields, Durham, United Kingdom. The dimensions of the vessel were 104.7 ft (32 m) in length, with a beam of 27.8 ft (8.47 m).

For about 20 years the Eleutheria traded around the world for various UK owners until late 1855. Voyages before coming to Australia included: London to Quebec, London to Londonerry to Bordeaux, Limerick to New York, and Liverpool to Barbados. The then barque arrived in Melbourne from Glasgow in 1854 with 21 passengers. She was advertised for sale while lying in Hobsons Bay. The Eleutheria was converted to a powder hulk in 1862.

On 14 November 1865, the Eleutheria was towed down Port Phillip with salvage equipment, divers and twenty men to the wreck site of the City of Launceston, where it was used as a floating platform, to set up salvage efforts on the sunken steamer.

Eleutheria Sinking — 5 July 1866

After a number of salvage attempts on City of Launceston, the Eleutheria was purchased by engineer Barrett, for £310 on 29 June 1866 and sold to a group of shareholders for a final salvage attempt, using the Eleutheria for lighterage, for which had been employed in previous salvage attempts. Used as base for operations, here it remained moored until 5 July 1866, when it was discovered to have sunk next to the wreck of the City of Launceston, with reportedly a lot of salvage gear on board. No efforts were made to salvage the Eleutheria.

Least depth of water over highest part of vessel is 7 fm (13 m).

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.
