Netizens Summarize Outdoor Knowledge Season Three: Diving Equipment Knows Shallow
Diving is a more professional sport. A good set of equipment can not only meet the needs of our underwater activities, but also can escort us. The following is a brief introduction to the equipment required for diving. In addition to the necessary diving divers in scuba or snorkeling: masks, breathing tubes, fins, but also: wetsuits, buoyancy control vests, respirator, instrument clusters, counterweights, and of course the usual accessories for diving equipment, including : Dive computers, sun protection clothing, diving flashlights, dive daggers, signal sticks, spools and diving kits. Currently internationally popular diving equipment manufacturers are: MARES, SCUBAPRO, AQUALUNG.
[Wet Suit] The main function of the wetsuit is to prevent body temperature from dissipating too quickly during diving, resulting in loss of temperature. Second, wetsuits can also be cut by reefs, and sea creatures such as sea anemones harm humans.
Mask and Snorkel Masks are divers' windows in the water. Since the density of water is greater than air, human eyes cannot be directly focused in water, so divers must wear a mirror to keep the air in front of the eyes so that the diver can only watch normally in the water. Persons engaged in diving activities should preferably choose masks produced by professional diving equipment manufacturers. Firstly, its material quality is better, and it is more comfortable to use in high (water) pressure environments. What is important is that these mirrors have very strict quality control during the manufacturing process, which can ensure the safety of use. Before and after diving, there will be a period of time floating or resting on the surface of the water. At this time, the diver can use the breathing tube to directly breathe the fresh air of nature without wasting the limited precious air in the cylinder.
[Fins] Fins allow divers to swim more efficiently in the water. Although the flippers have a variety of materials, styles, and characteristics, they all have two things in common: 1. Feet ; Used to fix the fins on the diver's feet 2. Frogs; Frogs connected under the feet to provide propulsion to the divers in the water Diving fins are more solid, flexible, propulsive enough to load divers and full set The weight of the diving equipment, while in the water must be neutral buoyancy or will sink.
Buoyancy Controller (BCD) A buoyancy controller is a device for controlling buoyancy in water. Basically, the BCD is made up of a balloon. The diver can freely control the inflation and deflation to control the buoyancy in the water. By properly controlling the buoyancy of the BCD, it is possible to offset the weightlessness of the divers in the water, so that divers can easily walk in the water.
[Regulators] Regulators are important equipment for controlling the air supply while diving. Since the first open regulator was invented, divers have not been able to move freely in the water. Current regulators used in recreational diving are mainly open-ended. The so-called open regulator is a diver who inhales the high-pressure air inside the cylinder via a regulator, and then discharges the exhaust gas directly into the sea, so it is no longer recovered. Therefore, it can be seen that the diver has a lot of air bubbles between his breath from the mouth. pop up.
[Dive Computer] The file cabinet can record various data of diving activities, and can directly provide divers with important parameters such as decompression time.
[Dive Knife] The diving knife is a very important tool and should not be considered as a weapon. One of the necessary equipment. It is the most effective tool for elimination when entangled with seaweeds, fishing lines, ropes or nets. Diving knives are generally made of stainless steel. The higher grades are also made of titanium alloy. The blade is made of plastic or rubber. The blade part should be sharply open on one side of the double edge and one side should be serrated. On the other hand, there should be a fishing line in front of the hand. groove. With cutting, cutting, boring, digging, knocking, stabbing, digging, sawing, measuring and other functions. The scabbard of the diving knife is made of rubber or plastic. There is a fixed knife clasp or sleeve on the scabbard to fix the diving knife on the scabbard, and two rubber bands can be tied on the scabbard.
[Submersible Gauge (SPG)] The necessary submersible instruments are pressure gauges, depth gauges, compasses, and diver's chronographs to check their status in the water at all times to ensure safe diving.
[Weight] Weight belt is commonly called lead belt. Its main function is to provide divers with negative buoyancy in water. The wetsuit itself has considerable buoyancy, so the weight of the counterweight belt is needed to offset, otherwise the diver will have difficulty diving into the water.
