1. Product introduction:
The product uses a pneumatic launching device to launch the lifebuoy to a distance that cannot be thrown by humans, and a rescue rope is installed on the lifebuoy. When a person falling into the water is found, the lifebuoy and lifeline are thrown above the water stream. The lifebuoy is dropped into the water within 5 seconds It can automatically inflate, and descend along the water to approach the person who fell into the water. The person who fell into the water just grabs the lifebuoy and the lifeline to be pulled to a safe area by rescuers and rescued.

2. Product advantages:
1. Security:
1. No explosion, only driven by air. It can be launched into or in flammable areas.
2. The product is equipped with several safety function devices to prevent accidental launching.
3. All projectiles are driven to maximum flight speed when they leave the launch tube. This ensures high accuracy of the projectile, and the influence of cross wind is extremely slight.
2. Economical
1. Low cost of use. The cost is only the cost of charging the cylinder after 4 or 6 launches.
2. All projectiles and ropes can be reused.
3. Can be stored for unlimited time.
4. The basic accessories include: 1 gas cylinder; 1 firing gun, 1 lifebuoy, 1 inflation tube; 5 plastic shells; lifeline 120 meters; 2 spare sealing rings; 2 spare 16g carbon dioxide gas bottles; 2 spare water-soluble tablets.

3. Product parameters:

1. Compressed air working pressure: 207 bar, the overall weight of the product is less than 3.5KG, and the projected mass is greater than 1.5KG.
2. Throwing distance: The distance of the automatic inflatable lifebuoy can be up to 60-100M when used in water, and 70-110M when used on land.
3. Line throwing size: ￠3mm×120M, the pulling force of throwing line is not less than 4000N.
4. Flight time: about 3-5 seconds.
5. The water buoy will automatically inflate into a lifebuoy within 5 seconds after entering the water, generating a buoyancy of over 8KG.
6. The product can be equipped with carbon fiber gas cylinder + quick connector (inflatable gas cylinder is purchased separately), which is light in weight and high in pressure; the automatic inflatable lifebuoy bullet is easy to install and replace, which can improve rescue efficiency.

4. Scope of application:
1. Water rescue: It is suitable for riverside, lakeside, riverside and seaside and other complex rescue sites, and can realize short-distance water rescue.
2. Land rescue: suitable for rope-throwing operations in rescue occasions such as civil, firefighting, ship-to-ship, ship-to-shore, tall buildings or mountain streams
