1. Marine life jacket: It is also one of the most commonly used types. It is made of EVA foam material and compressed into 3D three-dimensional shape. Its thickness is about 4 centimeters (domestically produced 5-6 thin hair materials, about 5-7 centimeters thick). Life jackets produced according to standard specifications have their buoyancy standards, generally 7.5 kilograms/24 hours for adults, which means that even after being immersed in the sea for 24 hours, their buoyancy can still reach 7.5 kilograms.

2. Automatic expansion type life jacket: It is generally used for fishing on boats, and the interior is made of double-layer high-strength chemical materials. In case of falling into the water, press the button on the right side, and the left side will automatically suck in air. The reflector will store the air until it is full. The buoyancy of this type of life jacket is relatively high at 10 kilograms/24 hours, but it should be prevented from coming into contact with reefs as much as possible to prevent damage.

3. Rock fishing cross arm life jacket: a rock fishing equipment with a pair of buttons in front of it, which needs to be pulled tightly when worn. In addition, there is a pair of oval shaped luminous bodies on the side or shoulders of the life jacket, mainly used for sea rescue. Therefore, when selecting, attention should be paid to whether the seams are open, and then the color tone and fabric should be considered.

To ensure its lifespan, it should be brushed inside and outside with a brush after each use, then rinsed with clean water and left to air dry in a well ventilated area. The fishing life vest not only has the functions of a regular life vest, but also has reflective and illuminated warning strips and a pocket device similar to the fishing vest, which can increase the safety of fishermen and provide enough space to place fishing accessories, killing two birds with one stone.
