Scuba Unit

The scuba unit is a diver's cylinder or scuba tank of compressed air, regulator, buoyancy control device (BC or BCD) and sometimes a weight system. Some diver'sprefer to use aweighted belt, but most diver's find it more comfortable touse the weight system that isbuilt into many buoyancy control devices. As part of NASEstandards forscubacertification divers mustbe able to assemble anddisassemble theirscuba unitin the water.

Fins

Fins, also known as swim fins or flippers are foot apparatuses made of plastic or rubber that allow divers to move through the water more quickly and easily. Fins can be a variety of styles including include full-foot models, heel strap, split, force, and paddle fins.Entry-level scuba diversnormally use paddle fins,whichare the least expensive and most versatile.

Masks

Masks allow divers to see underwater, there a variety of styles and colors to choose from to fit every face, fashion and type of diving. Experts suggest not being thrifty when choosing a mask, masks should fit and function as well as possible.

BCD

The BCD allows divers to control their depth by inflating or deflating a vest with the push of a button, some BCD's also have integrated weight systems.

Cylinder

A Cylinder or scuba tank is a tank of compressed airthat scuba divers use to breathe while underwater. The air is this tank is exactly the same as the air we breathe normally.

Regulator

The Regulator is a mouth piece that is attached to the cylinder (scuba tank)that acts as the delivery system of the compressed air from tank to diver.

Exposure Suit

An Exposure Suit is an entire suit that protects the body from cuts and scrapes as well as maintains body temperature. The type of exposure suit needed depends on the diving conditions.

• Body suits are for warm tropical waters, they cover the entire bodyexceptfor the hands and feet, however they provide little insulation.
• Wet Suits are best in temperate and tropical water, they offer full coverage and a greater level of insulation for maintaining body temperature while diving incooler water
• Dry Suits are full coverage and provide the most protection from cold water,but also allow divers in more temperate water to dive for longer periods at a time. Dry suits get their name from their ability to keep the body dry and are commonly worn in conjunction with a hood to protect the head.

Underwater Compass

An Underwater Compass helps divers to navigate while underwater, can withstand water and underwater pressure.

Diving weights

Diving weights help to offset buoyancy in order to swim more easily, commonly worn as belts but can alsobe integrated into BCdevices.

Whistle

A Whistel is a helpful signaling device while in open water, mirrors can also reflect light effectively to signal other divers, or boats Both a whistle and a mirror will prove instrumental for rescue in emergency situations.
