Whether it’s dark, foggy, snowy, or rough seas, you will easily locate the buoy. Lost fishing gear that litters the seabed has received increased attention in recent years. We have developed the buoy to help fishermen recover their gear and avoid ghost fishing. With the AIS buoy, you can track nets, traps, fishing lines, and other fishing gear. The AIS buoy has long durability and high precision. It is filled with foam to provide optimal protection for the AIS unit, which is placed in the center of the buoy inside a waterproof built-in cylinder. The AIS unit is delivered pre-programmed with the update frequency you prefer. A charger is included. Many choose to purchase an extra AIS so that they always have one that is fully charged and ready to use. (The buoy comes with 1 AIS unit)   Manufacturer: DAN-FENDER, part of Dan Hill Plast A/S, is one of the world’s largest manufacturers of fenders and buoys for marine sectors.
