Thanks guys,I would like to hear about your predation DougK I do believe they are they same or very similar. The Day stalker does take regular batteries. How is the volume on yours and how does it perform in the cold. It made it to -15 degrees here today and it is -29 degrees out right now. I called in one coyote late today with a homade hand call and I blew an easy shot, anyway thanks for any info.
