I have read about great advances in some of the electronic call systems on the market which include already down loaded multiple calls even with ability to switch between calls or have 2 calls at once. I have not found equipment for a hunter to tape sounds for a new call and to be able to add this sound track to an electronic call with enough volume and clarity to be useful. For example a hunter hunting bear with dogs had 1 dog killed and another injured by wolves before he and other hunters could get to were the dogs had a bear treed. If you wanted to use the sound of dogs treeing , what equipment would you use to record it and what equipment could it be added to for playing back? I am not sure this is the place for this thread, but did not see a better one.
