The new StopGull Air for pontoons and marinas, has been developed to be applied in areas that are very crowded by birds and that cause great problems, especially in the cold months, where these places stop being so heavily traveled by people and become busy. by seagulls. The Stopgull Air device is made up of a Stopgull Air XL and a base bag, which has been modified by giving it a larger size and installing a stainless steel structure under it that gives the device great stability and verticality, thus supporting most weather inclemencies. In addition, it has been equipped with a handle so that it can be transported and located where it is needed at all times.
