I've been looking for a GPS collar for over a year, hunt with a flusher for pheasants so it's not as important as those hunting thick grouse cover or wide ranging pointers that often go out of site. That being said I want one mainly for the peace of mind. For a long time I thought I'd go w/a Garmin Alpha 200i, after reading Chestle's post I'm leaning towards a Garmin 550+. I would love an Alpha, but wouldn't use 70% of the features and wonder about how to holster one. I believe dog stats can be tracked with a 550+ if used in conjunction with Garmin's phone app. As the dog is already collar conditioned I'm going to hold off on a gps collar and hope for a sale.
