I booked this activity with reservations about the cost - it appeared just too inexpensive to be any good. I even checked, on arrival, that we would get any diving at all. But it was awesome. I am past the first flush of youth (I have a bus pass!) so was in two minds whether to try something like this in case it was too cheap to be worth having or too cheap to be safe. Both were proved incorrect. The instruction was comprehensive and the dive gave us more than just a 'taster'. There are no corners to cut - you are either diving or you aren't - and we were diving! We saw fish, worms (and I mean worms as big as cucumbers), anemones, and other things that I can't recall the names of. The equipment was in very good condition and everything had been put in place to make it a memorable activity.
