The PADI Dry Suit Specialty is a great course as it allows you to dive in slightly colder waters found in the UK and several other places around the world. A dry suit seals you off from the water and keeps you comfortable, even in surprisingly cold water. There is incredible diving in the world's cooler regions and in some areas, conditions are even better in colder months. Becoming a dry suit diver allows you to expand your boundaries and dive more places, more often. In order to become a dry suit diver you must complete the the on-line learning and then complete two open water dives at the local training lake at Wraysbury.
