I have seen many years ago a game detector. It was like a fish finder but it was used for deer and other large game. It had a monitor that attached to your tree stand and showed movement about 80 to 100yds out around the tree and showed the direction of the game. I seen it on a commecial but cant find one anywhere. They make a fish finder for the anglers, we need a game finder for hunters. It allowed you to see game coming before you could hear or see them. Has anyone seen this, or know where or how to make one. I would really like to find one of these. Please help, Thanks.
