The thing most people forget about the inspiration, is that it is a budget model, the British Navy Re-breathers cost in the region of £50,000 each. I haven't dived on one but at that price I would expect it to work perfectly, As I paid less than 1/10th of that figure, I accept that there will be less than ideal features

As a budget model it features items that people, used to the best OC equipment money can buy, find substanded.

The most obvious item being an AutoAir, followed closley by the wing and harness. These are changable, but it is best to change them after you have had some experiance on the standard unit, so you know why you are changing an item.

If you are not confident enough underwater to accept the problems this method involves, then stay on Open Circuit until you are, no matter how long it may be.

If you are a confident diver, then I would recomend swopping to Closed Circuit, it continues the learning curve, has advantages in gas usage and deco times, and its a shiny new piece of kit. And as an added bonus, it keeps you on your toes by trying to kill you occasionaly.

Yes I do consider that last point an advantage. If you don't then don't buy one.
