The Flap & Scratch is one of the best calls ever made. Lightweight, compact, easy-to-use, and waterproof. Simply hold each end and pop, like a rag, to reproduce the sounds of birds flying up or down. By getting aggressive and adding fighting purrs, you get all the sounds of just that, two birds fighting. The most important sounds, feeding birds, are achieved by simply squeezing the bag with one or two hands. When you buy your new call, just grab both ends and push together, then wad up in a ball. This prepares the call for use. Then head to the woods!
