Thanks Dogchaser37 & Megasupermagnum for discussing the Pressure Trace system. I have looked at them but haven't been willing to spend the $$. I think that you may have pushed me over the edge. On a side note-- Dogchaser37 I have a sweet spot for GWPs. I had a small male for almost 15 yrs. He was the most versatile hunting dog I've ever hunted behind. He was a great family pet and too smart for his own good sometimes but we loved him dearly. He passed a little over a year ago and still miss him daily.
