Working as a wildlife presenter, I knew it would be useful to learn how to dive, but thats not why I did it. Id always been interested, and there happened to be an instructor at the BBC. He was a PADI teacher which, for me, was a stroke of luck, because it meant that I could do a referral.
I had one-to-one training for all the book- and poolwork in the UK, and flew out to Florida to do the open water dives. It was definitely the best way to qualify.

When it comes to training, theres nowhere better than the UK - a lot of dive centres abroad just want to push you through the course and get your money. And, anyway, who wants to study on holiday Theres a lot to learn, and it takes a while to get your head round it all, so you should definitely do the coursework before going away.
And when it comes to revising, I would strongly recommend buying the PADI training video. It was really helpful. I used it alongside the book and found it much easier to learn with a visual aid.
The problem is, if you do all your training in England, you end up doing your qualification dives somewhere like Stoney Cove (the most famous diver-training centre in the UK, a lake in Leicestershire).
Ive only dived once in England and consider it my worst-ever dive, so I may be biased, but I honestly think training in such conditions could put you off diving
for good. The water is freezing cold, the visibility is so bad that you can hardly see your own hand, and there just seems to be so much heavy equipment everywhere. As a hobby, forget it.

If you get a referral to somewhere hot, you have the best of both worlds, or at least you should do. My first training dives were a disaster. I arrived in Florida with a cold and had to delay the training for two days.
On the third day, I forced myself to go out on the boat, and felt so ill that I could hardly get the equipment on. So in the end I just did the dives in shallow water and went straight back to bed.
If you want to learn to dive, you must take it seriously. During the course, you are constantly reminded that its a dangerous hobby and that you cant afford to be complacent.

I wasnt a natural diver - the course work was more involved than I expected, and I really struggled with the exercise where you have to take your mask off under water. That was a few years ago, and Ive since done a few more qualifications - PADI Advanced Open Water, NAUI Advanced Shark Diver and PADI Speciality Diver Shark Awareness. I have just logged my 100th dive, but I still hate taking my mask off. I have very sensitive eyes and have a problem with salt water.
Unless youre diving all the time, its easy to forget your training, so dive centres will often make you do a pool session to check your skills before taking you out for the first time. I had to do a check last week when I was on holiday in Madagascar, and was surprised how rusty I was - I had to keep practising that mask exercise.
Being forced to do a pool check is a bit of a bore when you just want to get out and dive but, after last week, I realise that its a very good thing to do. It reminds you that your training doesnt end when you get your qualification card.

To anyone thinking of doing a dive course, Id say this: If theres even a little bit of you that wants to dive, then definitely do the training. You wont regret it. It is an incredible experience to go into an environment so completely different to our own - you almost feel you shouldnt be there.
Its such a rich world, an underwater rainforest with amazing wildlife, and so magical. I feel sad for people who never get the chance to see live coral. Its a huge privilege.

Final words of advice Find a good instructor, do the theory and poolwork in the UK, and get a referral to the Red Sea - its reasonably priced, easy to get to, and the diving is fantastic.
And dont worry about buying your own equipment - I cant see the point in lugging heavy kit around. Just buy a wetsuit, mask and fins, and hire the rest when you get there.
