Line Buoy is a large oval-shaped plastic floating platform. It is used in general for stripping along various water bodies, either in the sea, rivers or swimming pools. It is intended to be used to clearly divide the proportions of the area, such as sea buoys, shipping route buoys in the river, jet skiing, swimming pool, lanes for athletes etc. Under this buoy is fixed to the net which at the bottom needs to be weighted to keep the net from floating up. It's a good choice to use a galvanized chain attached to the net for weighting. Because in addition to the desired weight of the chain, the characteristics of the chain are suitable for free movement in the waves with long lasting consumption.
