Just a note to say thanks for a organising a great day out at the York Diver Training College. The chamber experience was really informative and I would recommend it to all recreational divers. It provides a real insight into something which we all hope we will never have to use in anger for a real emergency. The ‘Hard Hat’ dive was also a great session, showing us how diving used to be before the advent of SCUBA. Say a big thank you to Steve, Ian and Ricko at the college for such an enjoyable day, including the Yorkshire humour.
