All around in my hometown. people are frequently loving to celebrate the summer days with open water swimming events. By chance the organizer of swimming events, will take advantage of the opportunity to do water marketing with various forms of markers buoys, mostly, pyramid and square marker buoys were adopted by organizers.
At the same time, cylindrical marker buoys are also welcomed as they could be multi-functions. for example. marketing on the water or serving as perimeter buoys during the swimming event. the cylindrical inflatable race mark could stably and vertically stand on the water or horizontally laying on the water. fully display the sponsor's information printing on their bodies.
