I have heard people say this works great but I have been fox hunting seriously now for about four years and never not one time during hunting season have I had a fox, red or gray respond at all to the various sounds of another fox. Cant even get an eye. Puppies, adults, growls, barks, whines, the various distress noises, even the ones with a rabbit and fox both squealing. I have an e-caller with remote and all sorts of calls on it but only get a response from the basic cottontail distress. I could delete all the sounds but the rabbit and it wouldn't hurt my hunting at all. Using night vision and shine no lights and we have plenty of fox...killed 6 Friday night. What am I doing wrong if the fox sounds are supposed to work so good??? Have heard alot guys around here say just the opposite...they only see fox with a red fox pup distress. Only once did I see a fox with a foxlike noise, it was daytime three years ago in the early summer and a half assed bark brought two red pups back out into the open. Must be something I am doing, a few of the guys that use fox sounds are credible.
