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!

We're also breaking down the difference between the TT 15 and T 5 Garmin dog collars that are used along with the Alpha handhelds to track and train your dogs.

Track and train as many as 20 dogs up to nine miles away with the Garmin Alpha 200 GPS handheld. AND get enhanced mapping, easier operation, and more.

With this advanced multi-dog tracking and training system you get:

• • A larger, 3.5”, sunlight-readable capacitive touchscreen display for increased visibility in all conditions.
  • Configure your setup to specific hunt application needs while displaying only the relevant information necessary to accomplish a task.
  • Easily customize tracking and/or training functions through the handheld’s button operation, which allows for fast dog training cues and minor adjustments.
  • The new “quick key” functionality on the handheld allows you to easily and quickly access the most important field applications based on your hunting preferences, including dog list/group management, TopoActive terrain maps to determine best hunt routes, dog training and tracking data to help keep dogs safe and moving in the right direction, or important waypoint locations for efficient and effective in-field time management.
  • Multi-GNSS support and enhanced mapping systems in your Alpha 200 give you the ability to always know exactly where the hunt takes you.
  • A multi-GNSS satellite network that uses more satellites than traditional GPS alone for better tracking in challenging environments.
  • Preloaded Garmin TopoActive mapping and direct-to-device BirdsEye Satellite Imagery.
  • Connect the Alpha 200 to a Wi-Fi^® network and download BirdsEye Satellite Imagery directly to your device for a detailed landscape view of a region or use a compatible Garmin HuntView card (sold separately in U.S. or France markets) for a more detailed landscape overview.
  • Connect wirelessly to the Garmin Explore™ app on your mobile device for additional texting and mapping needs. When paired with a compatible Garmin device, the Garmin Explore app shows real-time dog tracking information, allows you to save collections of dog tracks and replay these tracks to review details of your hunt. Additionally, you can use the Garmin Explore website and app to help manage tracks, routes and waypoints, and review statistics.
  • Traditional compass mapping or the new Pro View feature that lets you locate your dogs at a glance. The system provides location updates every 2.5 seconds for up to 20 active dogs, so whether a dog is working in heavy cover or at a distance, a glance at the handheld gives you the ability to help pinpoint the dog’s location in near real time.
  • Store and share more than 20 dogs in an inactive state, so if you rotate different dogs or hunt with different dog groups, you no longer need to add or remove dogs in the system prior to a hunt. When an individual dog or group of dogs is not in use, simply make the collar ID or group “inactive” to take it offline.
  • Compatibility within the Garmin ecosystem, so you can track your pack from the road, your wrist, and other ways thanks to the Alpha 200 handheld's wireless connectivity with products such as Tread® powersport GPS navigator, rugged fēnix^®, tactix® and Instinct^® smartwatches, and other compatible devices.
  • Use with the TT 15 dog devices; training modes include 18 levels of continuous and momentary stimulation, plus audible tone and vibration activated from the handheld. Effective range for tracking and training is over 9 miles (depending on terrain).
  • A battery life for the Alpha 200 handheld of up to 20 hours.

The Alpha 200 comes bundled with a TT 15 or T 5 dog device. If you have compatible TT 15 or T 5 series collars , you can purchase the Alpha 200 handheld separately. The Alpha 200 handheld is water-rated to IPX7
