Scuba diving is an equipment intensive activity. However, many divers become equipment dependent, and this is unsafe diving. If the equipment fails or is used improperly, accidents can happen which the dependent diver may not be able to handle. Divers should achieve skills and be physically qualified to handle diving emergencies without the need for equipment. Most importantly, they should keep in mind that equipment does not create safety. It only lets you survive underwater. The diver's psychological and physical response to environmental conditions is what makes diving safe. The response permits development of skills, knowledge, experience, and watermanship to cope with specific conditions. Divers must never become equipment dependent and must be able to use their own abilities.

Divers should dive within the level of their training and experience. They should make responsible choices in their activities and should take their responsibilities seriously. Technical diving is a lifestyle and a sport of commitment. It is not for thrill seekers.

Most divers develop techniques, and to a certain extent, a pattern of diving compatible with their areas of underwater interest and dive objectives. The equipment you will need will depend on those interests and objectives. The basic needs for scuba diving are the exposure suit, buoyancy device, weight-belt, weights, mask, fins, snorkel, tank, underwater-pressure gauge, regulator, knife, and dive flag. However, other equipment is usually needed for the diver to accomplish the objectives of the dive.
