There has been one sound that for years has been the "go to" sound for Gray Foxes, it the old Johnny Stewart Gray Fox Pup Distress. Well , recently there is a second one that has been developed by FoxPro. It was introduced last year I believe. It is not a Mark II sound, but it is in the standard sound library. It's called Scream-N-Gray Fox , FoxPro sound number #226 , it works as well if not better than the old Johnny Stewart standby. I have both of them on my FoxPro FX5 and the newer sound is out performing the old JS standby. It is my finish the stand sound now a days, meaning when all else fails and I am about to quit the setup, I play it before I leave. Friday night, it brought in two in this manner and then one on Saturday night.
You can download it from FoxPro's website, no waiting just order and it is there.
