Well, This is the rest of the
gear, there are :
- An underwater compass, is a very handy navigational tool and is a common piece of equipment for divers to carry. Compasses can be attached to gauge consoles, worn separately on the wrist, attached to the band of a watch or dive computer, and digital compasses are now even built into the latest dive computers.
- Snorkel, is a plastic tube that allows you to breathe while you're swimming on the surface. It is normally attached to the left side of the mask. It's a great way to conserve the air in your cylinder while swimming on the surface. Snorkels also come with such features as purge valves (to make it easier to clear any water inside) and splash guards (to make it hard for water to splash in the top).
- Cylinder, he dive cylinder is what you use to carry your compressed breathing gas (usually air). Dive cylinders are typically made out of aluminum or steel and come in various sizes with the most common size being 90 cubic feet / 12 liters. Breathing gas is compressed inside the cylinder at up to 3000psi/210bar.
- Regulator, is a what you use to breathe the air from the cylinder. The regulator is divided into two parts: First stage is the component that attaches to the cylinder and converts the pressurized air inside to what's called intermediate pressure (less pressure than in the tank but still higher than breathing pressure). The regulator usually supplies air to the Alternate Air Source and BCD (Buoyancy Control Device) in addition to the Second Stage Regulator. It will also have an SPG attached to it.Second parts is the component that you put in your mouth to breathe. It reduces the air coming from the first stage regulator to ambient pressure (the right pressure for you to breathe).
- Depth gauge, this gauge shows you how deep you are. Depth is measured in either feet or meters.
- Dive Computer, also tell you your depth and dive time but it is also common for dive computers to calculate no-decompression limits over multiple dives. Many newer dive computers will also track air consumption and temperature and some even have built-in electronic compasses. Dive computers are commonly found attached to gauge consoles or worn on the wrist like a watch and can now be found built into masks.
- Dive knifes, It is good practice to carry a dive knife or shears. Dive knives are not used as weapons, they're used to free yourself from entanglement, particularly from fishing line. Many divers carry more than one knife for added safety and it's advisable to wear one on the BCD and one strapped to a leg.
- Hood, If you're diving in cold water you're likely to wear a hood. A hood is a neoprene cap that you wear over your head to keep it warm and can be thought of as an extension of the wetsuit.
- Slate, There are many different types of slates, but the most common are fish slates and writing slates. A fish slate is a waterproof plastic sheet covered in pictures and names of fish (and other creatures) the diver is likely to see. A writing slate is a blank piece of plastic with a pencil attached by a cord and is used to communicate by writing underwater, taking notes, or drawing. Slates are normally attached to a D-Ring on the BCD.
- Submersible Pressure Gauge, (more commonly called SPG) is the gauge that tells you how much air you have left in your tank. Air pressure is measured in PSI or bar. Most SPGs have a section of the dial highlighted in red which shows you when you're getting low on air.
- Weight System, Most people need weights to sink in water. There are two common weight systems: Weight belt and Integrated weight, Weight belt is most commonly a nylon belt which has lead weights attached. It is secured with a quick release clip at the front which can be released rapidly and easily with one hand if needed. And Integrated weight or Weight Pocket is attached on BCD, These pockets are secured using Velcro or quick release clips which can be released as easily as a weight belt. Most divers find integrated weights much more comfortable than a weight belt.
- Wetsuit, keep you warm while underwater. They are made from neoprene and designed to be worn snugly in order to allow little water to move against the diver's skin. They work by insulating the diver from the cold water. Wetsuits come in many sizes from one millimeter to seven millimeters or more, with the most common sizes being 3mm, 5mm, and 7mm. The most typical styles are: The Shortie style has short arms and legs and is typically worn in tropical water. A full one-piece suit that can, depending on thickness, be worn in cold, temperate, and warm water. This is a two piece wetsuit that overlaps to provide more warmth on the torso. The Farmer-John was previously quite popular but is now primarily used in cold water.
