The issue is that if I have a flushing dog and they are 15 yards from me in the thick bush then there is no way I would ever be able to get a shot. I would like to get something that will notify me that there is a bird there and let me get into position for the best possible shot before I or the dog flushes, if the dog is rooting around but I cannot see the dog or the bird then what is the point of having a dog.
