She ended up doing it with a diving school run by the husband of an employee of mine.

They were pretty cheap, but they seem a bit clueless.

It was a steep learning curve for her - and for me. I thought that it was just a case of strapping an air bottle on your back, sucking on a pipe and jumping in - I had no idea as to how much science and maths were involved!

She was a bit overwhelmed at first, but she got over it and now she really likes it (unfortunately as it's not a cheap hobby).

As for me, I think I'll watch that David Attenborough programme about fish on DVD instead - seems a lot less hassle!
