What can I do after this course?
Things to do after you qualify: Go on Dive Trips
At Wraysbury Dive Centre we organise dive trips both at home in the UK and abroad.   Trips are organised for all levels of diver.  Just keep an eye on our trips page here and on our facebook page for upcoming events
Things to do after you qualify: Buy Dive Kit
We would always recommend that you purchase your dive equipment from a dive shop rather than shopping online (and its not just because we have a dive shop on site).  Buying in person allows you to try things on so that you get the right fit, get the right advice and kit for the type of diving that you intend to do and benefit from the experience of those that actually go diving.  You may also end up with a better deal than you imagined.
