Diving mask: allows divers to maintain vision in the water and balance the air pressure between the mouth and nose through the mask.
Snorkel: used on the surface to save the consumption of air in the cylinder.
Cold weather suit: maintains the diver's body temperature and prevents damage caused by accidentally touching corals, jellyfish and other aquatic plants and animals to a certain extent. Cold weather suits are divided into wet cold weather suits and dry cold weather suits.
Gloves and overshoes: protect fingers and soles of feet, and prevent slippery falls or stepping on sharp objects during shore diving.
Counterweight: changes the diver's specific gravity and helps the diver sink underwater.
A set of fins: provides the diver with propulsion to move forward in the water (it can also complete backward movements, etc.).
Diving cylinder: stores compressed air used underwater.
One or two breathing regulators: adjust the compressed air in the cylinder to a breathable pressure for humans.
Buoyancy adjustment device: controls the wearer's buoyancy in the water through the gas in the air bag.
Diving Instrument set: usually includes depth indicator and tank pressure indicator.
Compass and map: used to determine underwater position and direction.
Dive computer: Dive computer can usually indicate current depth, recommended safety stops, surface rest time, and time to avoid flying. Dive computer equipped with wireless pressure transmitter can also display the current air pressure in the tank in real time.
Diving light: used to illuminate rock cracks and crevices, and for night diving.
Diving knife: not only a handheld tool, but also an important safety device.
Buoyancy bag: inflated when floating, used to alert the surroundings, especially ships, that there is a diver about to surface.
Thruster: a labor-saving device for diving.
Other accessories: such as underwater record board, ropes, hooks and other items that can make diving more interesting, such as underwater cameras.
