Garmin 320 trouble

Are you giving the handheld and the collars time to connect with all the sats that they can before you move off from the truck? I think that's one reason folks don't get the optimum use out of their Garmins. It seems to cut way down on trouble for me if I turn everything on and lay them on the dogbox for about 5 minutes or so. Make sure that your collars are triple blinking before you put them on a dog and that the handheld has contact with each collar. I may just be lucky but I have very little trouble with mine......I spend more time on the map page than any other.....the Birdseye deal is as handy as a pocket on a shirt. Good luck with it next time.
