The 8-note call of the barred owl has a rasp that is heard only when you are extremely close. This is the sound that Primos found turkeys will respond to the best. The Power Owl has been designed to accurately reproduce this sound with strong volume to locate even the wariest of gobblers. The Power Owl is great for loud hooting. It provides automatic back pressure and the improved design keeps the reeds from sticking due to over blowing.
