In addition to the metal windscreen that comes with the Sanken Cos-11 there is an optional but less known Large windscreen that can be purchased seperately for about $25.00. This windscreen is outstanding it can withstand even beach force gusts without having wind noise problems. It is my first choice for high wind situation so order one it may save your day!!!! Thanks for all your great emails everyone. Visit the Link below to see the Windscreen:
