This granddaddy of a call, the Old Man, is the longest call in the LG goose call line up and is designed with a longer barrel as well as a longer insert with tighter interior dimensions to provide greater constriction and deliver a deeper tone. The longer insert creates a smooth, hollow tone that breaks over easy. It is their easiest call to blow in comparison to shorter and the more aggressive calls; ...but hey, you young pups, don't cut this Old Man short, this call still has the muscle to get aggressive.
