There is an option to only track a selected pup and another option to both track and train a chosen pup. You can do this with only one or a pair or multiple dogs at the same time. The transmitters send location pings for every 2.5 seconds which shows the precise locations of your dogs, near-to-real time account.

Garmin Alpha 100 Tech Specifications

Our research shows that there are several tech specifications Garmin Alpha 100 presents to its users that can easily make you decide to opt for it even with its high price.

Communication Range

When using Alpha 100 with Garmin TT5 15 collar, the light of sight can reach up to 9 miles, but only up to 4 miles when using the mini version of TT5.

Location Tracking Precision and Accuracy

This device, like other products of the Garmin brand (e.g. Garmin Astro 430), is also integrated with GLONASS positioning system; this advanced technology makes it easier in locating and tracking pups even when in complex terrains as it sends you location pings at a 2.5-second rate. At this location update rate, it can surely pinpoint the exact or near-to-real time whereabouts of your dogs within a 4- or 9-mile radius.

Battery Life & Rescue Mode

Alpha 100 uses a rechargeable lithium-ion battery pack which is already included when you buy the product. This one lasts up to a maximum of 20 hours, but this device has a Rescue Mode option that when enabled, extends the battery life 25% more, although this mode will automatically slow down the location ping rate from 2.5 seconds to a 2-minute rate. The Rescue Mode can give you more leeway to find your lost pup as it can extend battery life for up to 12 more hours.


Garmin Alpha 100 is given a water rating of IPX7 which makes it waterproof and can therefore withstand rough weather.

Display, USB, & Memory

The display size of Alpha 100 is 1.53 x 22.5 inches (W x H) and 3 inches (diag) with a resolution of 240 x 400 pixels and a transflective 65-K color touchscreen. This touchscreen device is glove-friendly so you don’t have to worry about removing your gloves when hunting in cold winter weather. It can conveniently hold up to 4 GB of data and history. This device also has external memory storage but the microSD card is not included in the package.

Garmin Alpha 100 General Features

Like any other products under the Garmin brand, Alpha 100 also comes with an already preloaded TOPO US 100K map. It also has an added feature of a barometric altimeter and 3-axis electronic compass that makes its tracking and locating ability more accurate. This device also has a geofence that allows you to customize the virtual boundaries on the map for when your dog strays out of the zone, it will then send you an alert so you can recall and train them to go back to the safe zone.

Track and Train

Most probably the best feature of this product is its track-and-train ability of up to a maximum of 20 of your sporting or hunting dogs, all at the same time using differently colored collars and coded profiles in the device. Alpha 100 is integrated with Tri-Tronics® dog training technology that uses a variety of training features like different modes of stimulation and different ranges of intensity.

There is a compass screen where you can view the direction traveled, speed, and distance of your dogs away from you. With this information, you can correct and “train” your dogs without incorrectly correcting others.

This gadget also has the BirdsEye Satellite Imagery which shows the user a bird’s eye view of different places and terrains like roads and parking spaces, and even rivers and streams.


The BaseCamp software of Garmin Alpha 100 lets you view and plan your routes and tracks when going on an adventure. This software shows a topographic map on your PC which also includes elevation and contour data, and gives you the option to view them in 2D or 3D.

Is it worth it to pay for Garmin Alpha 100?

We believe that Garmin Alpha 100 is worth it to pay for because this highly technological device can not only let you track your dogs but also train them at the same time that you are tracking them without compromising its efficiency and preciseness of either of these functions. It makes your hiking, training, and hunting days with your dogs easier even if you are just a beginner.

Our Conclusion

There is so much to love about this product. One is the reception capability because even when you are deep in the forest or wooded areas, you’ll easily be able to locate your dog even at longer distances showing you their movements and relative distance to your location. Secondly, because of its waterproof rating, you will be able to track your dog seamlessly even when they are having a swim at a river or a lake as it is proven safe to be used underwater. Lastly, its track-and-train capability is the one dog trainers will surely appreciate in Alpha 100! The only thing we do not like is the cost, but all these features surely complement the hefty price. We included Garmin Alpha 100 on our list of the best Garmin dog e collars.
