A typical Scuba suit consists of the following equipment in order.
- Breathing apparatus – This is what provides oxygen to the diver and also regulates the supply based on depth one dives to. Common breathing apparatus include the half mask covering just the eyes and nose with a mouthpiece that comes from the supply canister behind. It can either be an open–circuit or rebreather apparatus.
- Gas Mixture – Typical gas mixtures are similar to what we breath above sea level that is 21%-78%-1% N-O-T. However, there are other mixtures available depending on the competency level of the diver. One such commonly used mix is nitrox which is also called Enriched Air Nitrox and it has extra oxygen with around 32 to 36 percent. This is to reduce the risks one faces due to decompression sickness. Plus, it helps in quicker dives.
- Diver Mobility – It can be in the form of either fins attached to one’s feet or propulsion devices.
- Buoyancy control – To control the rate of ascent or decent in water, divers must rely on buoyancy devices. These depending on the suit help in achieving neutral buoyancy thus reducing the swimming effort necessary to stay at a specific depth. Naturally, proper buoyancy helps reduce gas consumption too.
- Diving Masks – Either it can be the half mask or a full mask. When wearing a flat lens, the refraction error of light traveling through water and as it enters into air makes the surroundings look about 25% closer and 34% larger than they actually are. Unfortunately, this reduces field-of-view and hand signals are necessary for coordination.
- Dive Suits – Dive suits are designed to keep your body warm and help in buoyancy as well. It can be either wet or dry suits. The later, as the name suggests, keeps your entire body dry while the former is only there to keep your body warm enough during dives.
