Scuba diving for Underwater

The Scuba was designed for use with Underwater, because a human like us cannot stay with a few times in Underwater. So many diver created and developed the Scuba accessories for use in the place that they want to explore.

Scuba diving

The scuba meaning from Wikipedia show below;

SCUBA (Self Contained Underwater Breathing Apparatus) diving is swimming underwater, or taking part in another activity, while using a scuba set. By carrying a source of breathing gas, the scuba diver is able to stay underwater longer than with the simple breath-holding techniques used in snorkeling and free-diving, and is not hindered by air lines to a remote air source. The scuba diver typically swims underwater by using fins attached to the feet. However, some divers also move around with the assistance of a DPV, commonly called a "scooter", or by using surface-tethered devices called sleds pulled by a boat.
Scuba diving is still evolving, but general classifications have grown to describe various diving activities. These classifications include:
• Commercial diving
• Military diving
• Naval diving
• Police diving
• Professional diving
• Recreational diving
• Rescue and recovery diving
• Scientific diving
• Technical diving
o Cave diving
o Cavern diving
o Deep diving
o Ice diving
o Wreck diving

Moreover if you want to explore or going down the Underwater, you must have Scuba certificate. Scuba diving requires certification, which can be done through a number of scuba diving agencies, including SSI, NAUI and PADI. Scuba certification agencies are all basically the same in everywhere around the world. You also need this license for hiring the scuba options from scuba shop.
