If you are not using steel scuba cylinders, try to use one and you will soon realise what you have been missing.
In general, most experienced divers prefer the buoyancy characteristics of steel tanks to those of aluminium. Steel cylinders are lighter on land than the same capacity aluminium cylinder, but heavier (more negatively buoyant) in the water. This characteristic has many advantages. The greater negative buoyancy allows the diver to remove lead weight from their weight belt, or integrated weight system of the BCD, allowing the diver to better distribute weight by moving it to the rear of the BCD, a great advantage when wearing a back inflation style (Wing) BCD.
With aluminium scuba cylinders, as we breathe the weight reduction of air in them typically creates positive buoyancy at or near the end of a dive. Thus you need to carry extra weight to compensate for this. The steel cylinder with its negative buoyancy throughout the dive allows you to shed the excess lead that is required to keep you properly trimmed while you dive an aluminium cylinder.
Divers in cooler temperate waters most commonly use the following three Faber steel tank sizes:
Faber 3 Litre (25 cubic foot), 232 bar, 100 mm (3.9 inch) diameter, are the popular choice of rebreather divers.
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).
This PADI Digital Underwater Photographer specialty course helps you easily achieve great photo and video results. This course also counts towards the Advanced Open Water Diver course and your Master Scuba Diver rating.
Through hands-on training during two scuba dives and guidance from your PADI Professional, you'll discover:
Age Requirement
16 years or older
Course Prerequisites
PADI Open Water Diver certification, or proof of entry-level diver certification from another training organisation
Time Commitment
Approximately 12 hours
Beyond using basic scuba equipment, you'll need a digital underwater camera, plus a computer or other device for downloading and viewing your images. Your PADI Professional may suggest additional equipment and accessories depending on your camera system.
Personal Equipment — You'll need to provide your own bathing suit and towel. For your personal hygiene and comfort, there are some things that we simply choose not to provide you with, and this is more out of concern for your health and well-being than anything else. These include:
If you don't already have them, you can buy these items in our dive shop online or in-store. Our experienced dive shop staff can help you with the right equipment choices.
Rental Equipment — Rental gear is not included in the price. The Scuba Doctor has high-quality BCDs, Regulators with Dive Computers, Scuba Cylinders, Wetsuits and Weight Belts available for hire. See Scuba Equipment Rental for details.
