A try-dive entitles you to two one-hour sessions with a qualified HGSAC try-dive instructor, where you'll be introduced to SCUBA equipment and SCUBA diving in the safety of a pool environment.
Some basic skills may be introduced, but the emphasis will be on having fun and getting a feel for what scuba diving involves.
All equipment is provided. You will need a towel, swimming costume and a t-shirt you're happy to wear in the pool.
You don't need to be an athlete, but you do need to be medically fit. Please see the medical form here:
You also need to not be suffering from a cold, ear infection or other such illness at the time of try dive.
