I have a hearing problem( or so the wife says anyways) and a few years back I bought a Walkers Game Ear 2. Although I liked the fact that I could hear alot of things that I`d have missed without it I also found it hard to pinpoint where the sounds came from. I talked to a hearing specialist about that and he recommended that I use 2 of them as that would help distinquish the location of sounds. I never did buy a second one and ended up selling mine to a hunting buddy. He loves it.
