I wanted to share my experience with a product that Susan Ross shared with me. It's called Whistle, a GPS device that you can attach to your dog's collar and track them from your smartphone. So far, I've only used it one day, but it saved me a lot of walking to look for my dad's squirrel dog. Its biggest limitation is that it requires cell service on your phone. When in service, though, it works great. There are a lot of unnecessary features for hunters (sharing to social media, activity trackers, etc.) but the piece of mind in being able to see the dog on the map is great. The best part is that it is a MUCH cheaper than a Garmin or SportDog GOS collar, assuming you already own a smartphone. I will still be getting an Alpha when I can afford it due to it relying on GPS and not cell service, but this will stand in until then.
