Buoy floats, buoy weights etc.
Sort after:
The buoy floats and buoy weights are used for mounting buoys to be used for marking fishing nets at sea. These materials are sold to the fisherman who wants to mount his buoys himself. They are also part of the production of pre-assembled buoys.
Remember that your buoys must be at least 1,2 meters above the water surface and the weight at the bottom has to be heavy so that it does not turn around in the water surface at the sleightest wind.
