Whether you're hunting or training—or both—find the best GPS handheld for managing your dogs in this Garmin Alpha 10 vs 100 vs 200 vs 200i comparison. In 2014, Garmin partnered with Tri-Tronics® to bring the first Alpha GPS track and train system for sporting dogs—the Alpha 100. Then in 2020, after asking their customer base of outdoor enthusiasts how they could make this dog tracking and training system even better, Garmin released the Alpha 200i with inReach capability and several other feature enhancements. In 2021, Garmin introduced two more models in the Alpha lineup to give you more options in how you monitor and control your hunting dogs. The compact Alpha 10 offers flexibility in the field, and the Alpha 200 has all the features that the Alpha 200i has—without the inReach technology. In this comparison, find out what makes these multi-dog GPS handhelds unique so you can get the right Garmin for you and your pack!
