Doubles & Stages

To the uninitiated a dive tank is just a dive tank. They wouldn't know that some sets of Double Tanks are heavy at the manifold and some are shorter and so your wing tends to get caught and scraped under the heavy cylinders. The best type of UK tank to get which prevents both of these problems is the Eurocylinders Twinset. You also need to know that an Ali 80 Stage that has a reinforced neck and can be pumped to 232 bar just won't quite trim out right under water, not so with ours - designed to the original 207 bar spec.

These are the things that you learn with time and experience. If you buy your DIR Tanks from this section, you can get the benefit of our experience, and can be assured that you are getting the right kit for your diving and you'll be making a purchase that will dive just beautifully.
