WTF, 1000 yards??
I changed my post, I was going to post the below thoughts...
Are you saying; The dogs you are hunting with, are frequently 1,000 yards away from you....while you are hunting....over a half mile? If so, try using the stimulation feature....isn't that kind of what it is for? Maybe more information is needed, what kind of dogs, grey hounds? You aren't confined to a wheelchair, are you? I really don't understand stand how that happens, what are you doing while they get that far away? Is this a common practice for pheasant hunters today? That goes against what I preach to everyone I hunt with, "pay attension to the dog and always be ready". I guess if you don't do this, you do need one of those systems. Reflecting on this, is it that the habitat where you are hunting, there are very few birds and it just isn't worth the energy to hunt with the dogs? That just seems bizarre to me, unless you were hunting raccoons. Even if you meant 100 yards away....
I really hope I am not understanding that post correctly, cause you are missing out on 90% of the dog work, if that is how you hunt.
