I’ve been using the Gamin Astro series for a number of years. The 430 is a great product. I’m using it to track 2 dogs at a time as well as making bird flushes and also to help me find my way out of the woods. It pairs with the Fenix line of smart watches so that you can see where your dogs are right on the watch. It has totally changed my hunting.
