Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba), which is completely independent of surface supply, to breathe underwater. It can be done in open water or in swimming pools.
An Overview of Scuba Diving
The British Sub-Aqua Club or BSAC is the national governing body of recreational diving in the United Kingdom. You can learn to scuba dive with a BSAC club - start your journey by finding your local scuba diving club and booking a taster dive with a Qualified Scuba Instructor.
Swimming underwater gives you a great cardiovascular workout and builds muscle strength with low impact on your joints. It can also boost your well-being and reduce stress through deep, regular breathing, and as a highly social activity is a great way to meet new people.
Most BSAC clubs offer 'Try Dives' in a pool or sheltered water and will provide all the equipment. All you need to bring is your bathing suit and perhaps a t-shirt to wear over it. Once you start your Ocean Diver training, it's a good idea to purchase your own basic gear – a mask, fins and snorkel. When you progress to open water and especially in the UK you will require a wetsuit or drysuit. These can be hired from clubs and dive shops, but you may want to purchase your own to ensure a good fit and familiarisation.
The deepest diving pool in the world is Y-40 in Padua, Italy. It's 42.15m deep and includes an underwater tunnel, caves, and platforms for dive training.
