Diving gear for diving suits

Diving equipment - the diving suit is a diver's second skin, its importance to the sport of diving is self-evident.     Its primary function, number one, is to keep warm, yes!  Don't think that diving in the tropics doesn't require warmth. Water has 28 times the heat transfer capacity of air, and even standing still uses a lot of energy.  Like a scalding egg, it cools much faster in water than in air.  So the same 26 degrees Celsius you get hot onshore, but you get cold underwater.     Two is from the bottom of the scratch, animal and plant direct contact according to the damage.  Be stung by coral and so on carelessly very "sour cool"!     Dive suit can also prevent sunburn, do not think in the sea will not get sunburn, clear water can isolate the heat of the sun, but ultraviolet light can penetrate the clear water and on the surface of the water due to the refraction of the surface, ultraviolet light will be more intense, so the sun protection of the wetsuit is still very important.     Classification of wetsuits:     1. The jellyfish     It's the most basic type of wetsuit, and it's usually made of very thin material.  It's designed to protect you from accidental bruises and stings from jellyfish and other aquatic creatures. It's also designed to protect you from the sun. Another use is that wearing a thin jellyfish suit makes it easier to put on wet clothes.  Jellyfish jackets offer little protection from the cold.     2. Wet suit (wet suit)     The wet suit is made of foamed rubber or nylon cloth and is worn close to the body.  The wetsuit must fit well against the skin, and the small amount of water that enters the suit does not flow between the skin and the suit to keep the body warm.  Divided into half and whole body by style, and divided into 3mm, 5mm and 7mm by thickness, the more fit your wet clothes are, the less sea water that can touch your skin, and the more warm your wet clothes will be underwater.  Different styles and thickness can be selected according to different water temperature.     3. Dry suit (dry suit)     Dry suits are suitable for cold water diving, the general water temperature is less than 10 degrees Celsius you need to wear dry clothes into the water.  When wearing a dry diving suit, the body is completely isolated from the water. According to the water temperature, you can wear warm clothes, sweaters and fleece jackets inside to strengthen heat preservation and heating. It is the best diving suit for leisure diving heat preservation.  Using a dry suit requires special training, learning how to control and use the gas.     Tips:     1. There are two kinds of divers in the world. There are those who admit they pee in their dive suit, and those who don't.  So if you do a lot of diving or go once or twice a year it's better to buy your own wetsuit.     2. It's best to buy a wetsuit offline, because the most important thing about a wetsuit is that it fits well, so try it on when you buy it.     3. Diving material is a kind of synthetic rubber foaming body, delicate feel, soft, elastic, shockproof, heat preservation, elastic, impervious to water, impervious to air and so on.  Our usual use of mouse pads, backpacks, and so on are also made from diving materials.     4. After diving, the diving suit should be soaked in water and avoid sunlight exposure, and stored in a cool and ventilated place as far as possible.  Zippers should be lubricated frequently and should not be folded for a long time to prevent irreparable crease caused by foam synthetic rubber.     Diving equipment, diving supplies manufacturers  http://www.haiyundive.cn/
