Advice

Steel vs Aluminium is a question we're asked all the time. And it's a good one! There is no short answer and it is really dependant on several factors.

1. Price - Usually there is quite a difference between Steel and Alluminium cylinders; this has been fixed by our current pricing as there is now very little difference, although at some other shops it is still significant. 

2. The amount of air you actually need - The most popular steel cylinders are the big ones! The 15 litre holds around 30% more air, and is slightly shorter than the big aluminium. Both 12 litre models hold 10% more air but are also 10% lighter and the "Dumpy" version is only 2/3 height of the big aluminium! This is a big advantage carrying and storing this size cylinder, but best of all, it is so much easier to sit down while wearing your gear!

3. Air Consumption - If you are breathing through your cylinder faster than the buddies you are diving with, then the bigger steel cylinders are a great way to even up the game! If you go through your air at the same speed or slower than your buddies, it is a waste of time having more air, as you'll have to come up when your buddy does anyway! Stick with the same size cylinder that they use.

4. Warranty - You get a 15 year warranty from date of manufacture with Luxfer Aluminium cylinders, 10 years on Catalina Aluminium cylinders, but you only get a 5 year warranty with Faber Steel.

5. Buoyancy - All cylinders get more buoyant as they empty, however there is a difference between steel and aluminium. Aluminium will become positively buoyant when low on air, steel cylinders are still slightly negatively buoyant when low on air. This means with steel, you don't have to wear extra lead to counteract that buoyancy at the end of the dive, and a lighter weightbelt is a good thing!

6. Corrosion - Faber steel cylinders are Zinc coated on the inside and under the paintwork on the outside, to try and stop rust, but scratches and Hydrostatic test marks will rust eventually. And if you get a fill with to much moisture or accidently "fully" empty your cylinder, it could start rusting inside! Not good!! (Ensure you only get fills from a reputable air source). Click here to see the "peace of mind" you get with Dive Centre Air! Aluminium cylinders don't rust, so from a maintainence issue, you don't have to repaint or rub down alluminium cylinders, and although it is recommended for aluminium, washing down steel cylinders after use is required! You can get a build up of aluminium oxide (white powder) inside aluminium cylinders from to much moisture in bad air, but this is easily fixed by us, and causes no real damage to your cylinder. A steel cylinder with rust inside has to be "rumbled", and this is expensive, takes time and has to be repeated usually every year!

As you can see, there is a bit to this decision. :-)

But once you own your own cylinders, going for a dive is so much more convenient, because there they are, sitting in your garage, full of air, and ready to go!
