1 thought on “Garmin Astro 430 Review: GPS Dog Tracker”

  1. We purchased a 430 in our group of houndsman and found out you can not run the same t5 collars together with the 320. I would recommend going with sport dog from here on out. I have ran Garmin for years and I am tired of new models not working with existing products. Specially when you are spending thousands of dollars on their products.
