Whether you're hunting or training—or both—find the best tools for managing your dogs in this Garmin Alpha 100 vs 200i comparison. In 2014, Garmin partnered with Tri-Tronics® to bring the first Alpha GPS track and train system for sporting dogs. 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 pretty much enhanced everything! In order to help you decide if the Alpha 100 multi-dog tracker and trainer is enough for you, or if you should pay more for the more advanced yet easier-to-use Alpha 200i, we created this comparison. And 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.

    • The confidence of knowing Alpha 200i gives a new level of peace of mind and global communication coverage through inReach satellite technology. With the 100 percent global Iridium® satellite network, you can send and receive messages, navigate your route, track and share your hunt, and if necessary, trigger an SOS to get help from a 24/7 global emergency response coordination center—directly from the Alpha 200i handheld or from a compatible device (active satellite subscription required).
    • 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 200i handheld's wireless connectivity with products such as Garmin DriveTrack™ 71 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 200i handheld of up to 20 hours or up to 15 hours with inReach technology enabled.

The Alpha 200i 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 200i handheld separately. The Alpha 200i handheld is water-rated to IPX7


What's the Difference Between the TT 15 and T 5 Garmin Dog Collars

The main difference between the TT 15 (red collar) and the T 5 (blue collar), is that the TT 15 can be used for tracking and training, and the T 5 is only for tracking.

Both devices are top-mounted, high-sensitivity GPS/GLONASS receivers and come in regular (up to 9 miles away) and mini models (up to 4 miles away). The TT 15 and T 5 Garmin dog collars are compatible with both the Alpha 100 and the Alpha 200i handhelds. You can bundle the Alpha 100 with the TT 15 or the TT 15 mini collars. You can bundle the Alpha 200i handheld with the TT 15, TT 15 mini, T 5, and T 5 mini. Find all of these on the PlayBetter dog tracking and training page!

The T 5 Dog Device

Uses LED beacon lights activated from its compatible handheld device. The lights work in low-light conditions and at night, and are visible up to 100 yards away.

This tracking-only dog device with collar is tough enough to run wherever your dog runs, up to 9 miles away (4 miles for the T 5 Mini).

The TT 15 Dog Device

Uses 18 levels of continuous and momentary stimulation, plus audible tone and vibration activated from Alpha® 100. Compatible with Astro® 430 and 320 for tracking only.

This tracking and training dog device with collar is tough enough to run wherever your dog runs, up to 9 miles away (4 miles with TT 15 Mini). The stimulation features let you train each dog separately—traditional stimulation allows you to make quick changes (low, medium or high) within a predetermined stimulation level (1-6), whereas linear stimulation allows progressively more stimulation from levels 1 to 18. You can remotely operate the LED beacon lights, built in to the dog device, to help locate your dog in low-light conditions.
