Hunter's Specialty makes the true talker and this is what I use. It works great. I have had a deer stare right at me and take off running. I use this call and stop him dead in his tracks. Wait a few seconds and call again and he comes running back to me! This has happened with mulitple deer with this call! No adjusting a tube...just push down on different spots to create a big buck, small buck, doe, fawn, or yearling sounds. Great call!
