Fujairah represents the perfect training ground with plenty of sub 20m dives that make it easy to do 3 dives a day without getting exhausted! some of the best lofe is in less than 10m of water and so your air will last for an hour at least.
I dived with Divers down in Dibba and for me they are great ! not too much of the Caribbean 5 star glitz but great at helping you to enjoy the diving. Small things like planning ahead so that your not making trips to the boat or the changing rooms when you can just leave kit where you will need it in a couple of hours.
