During your Open Water course, you learned some of the limits of diving on normal air, and how nitrogen affects the body when we go scuba diving. During our dives, nitrogen is absorbed into our body tissues and this limits our diving depth and time. As you learned in your Open Water Course, too much Nitrogen can be a bad thing.
Many Nitrox divers also claim to feel much less tired after diving on Nitrox, and for those of you who are feeling a little less fit than you used to be, less nitrogen in your body can only be a good thing - especially if you're planning a multi-day diving trip.
The Nitrox theory typically takes 2 or 3 hours and is completed the day before your Nitrox dives. The theory session is followed by a trip to our local 'Nitrox' filling station where Nitrox production will be explained and you can see the system for yourself. You'll also analyse your own tanks for 2 dives on Nitrox the following day.
During your course, you'll also learn how to use a Nitrox diving computer, how to set and check the computer. If you don't have your own Nitrox dive computer, we'll give you one to use during the course for free.
Whilst scuba diving is a very safe activity, it is important to know that you are fit to dive and that you do not have any medical conditions that could increase your risk of an accident underwater.

If you answer 'yes' to any of the medical questions, please print the entire form and take to your family doctor who will assess your fitness to dive and issue a medical statement which we must see before you start diving.
