Garmin Alpha 100: Review (Handheld Only)

View On Amazon

Something important to note is that the Garmin Alpha 100 is the handheld device itself which controls the TT15 and T 5 collars for example.

This is a review of the Alpha 100 handheld in relation to the collars as a system. 

You can check out the TT15 and TT15 Mini collar review in this guide.



It has the capability to track up to 20 dogs or other hunters – from up to 9 miles (TT 15) or 4 miles (TT 15 mini) away

It works by receiving signals from additional Alpha 100 handhelds, TT 15 and TT 15 mini dog devices (each sold separately). 

It can also receive tracking only signals from a T5 collar device

The handheld comes preloaded with TOPO U.S. 100k maps

It can measure a dog’s speed and distance travelled

It can track the direction your dog is travelling

It can receive notifications when your dog is ‘Treed’ or ‘On Point’

It updates your dog’s location as often as every 2.5 seconds

You can use the handheld and tap the screen with gloves

When using a vehicle to find or follow your dogs, the Garmin DriveTrack™ 70 dog tracker and GPS navigator (sold separately) provides an easy-to-watch “big picture” solution. The 7-inch moving map display shows dog positions overlaid on TOPO contours or satellite image views – along with navigation cues that help point you to your dog’s current location.

BirdsEye Satellite Imagery (subscription required) is an add on that allows you to have a better-than-real-life view of terrain, including roads, water, woods and more.

You can also get the free software – Basecamp. It allows you to view and organize maps, waypoints, routes, and tracks. This free trip-planning software even allows you to create Garmin Adventures that you can share with friends, family or fellow explorers. BaseCamp displays topographic map data in 2-D or 3-D on your computer screen, including contour lines and elevation profiles. It also can transfer an unlimited amount of satellite images to your device when paired with a BirdsEye Satellite Imagery subscription.

You also have the option to use your computer as a tracking station. You can load your laptop with BaseStation software to turn it into a field control center for tracking multiple dogs and/or buddies (up to 20 Alpha units, TT 15 or T 5 dog devices). View real-time GPS information on the larger display of your computer, making it ideal for canine search and rescue teams. And because it’s GPS and GLONASS, you’ll get safe, secure and more effective tracking, even where Internet and cell phone service isn’t available.



The handheld has the capacity to help you train your dogs separately e.g. to stop chasing unwanted game

The static stimulation system has 18 training levels which are 18 different level of stimulation

There is the option for continuous and momentary stimulation

There is a tone/sound training option

There is a vibration training option

There is a lockout feature you can enable so that you don’t accidentally activation the static or sound training cues

With the stimulation modes – there are actually two to choose from. There is traditional stimulation that allows you to make quick changes (low, medium and high) within a predetermined stimulation level (1 through 6), whereas linear stimulation allows progressively more stimulation from level 1 through level 18. 



Handheld dimensions are 2.5 x 6.5 x 1.5” 

Handheld weight is only 8.8 oz

Handheld is waterproof to IPX7 – which means it’s submersible in up to 3 feet of water for 30 minutes

Handheld display screen is a transflective, 65-K color, TFT touchscreen, and measures 1.53″W x 2.55″H. The resolution is 240 x 400 pixels

Comes with rechargeable lithium ion batteries that provide a battery life of up to 20 hours

There’s 4.0 GB of memory space on the handheld, and it has a USB interface



The handheld has the ability to add maps

There are base maps that come with the handheld. Topographic maps are preloaded

The maps are stored on a microSD™ card

You get up to 4000 waypoints/locations/favorites

You get up to 200 routes

With the track log, there’s 10,000 points, and 200 saved tracks



There’s a baromateric altimeter

There’s a tilt compensated 3-axis compass



There’s the ability to area calculation

There’s automatic routing (turn by turn routing on roads)with optional mapping for detailed roads

There’s capacity for custom maps

You get a hunting/fishing calendar

There’s also sun and moon information

There’s also the ability to use Garmin connect – an online community to share data and use it



People mainly choose to use the Alpha 100 with the TT15, TT15 Mini, or the T5 collar devices

The TT15 models allow tracking and training, whereas the T5 model is tracking only

You can extend the battery life of the TT15 models by switching to rescue mode. At 25% battery, the location update of your dog slows down to 2 minutes from 2.5 seconds, to conserve battery.

Range from handheld to collars are 9 miles for the TT15, and 4 miles for the TT15 Mini

There’s a MURS frequency band for the collars (The T 5, T 5 mini, TT™ 15 and TT 15 mini are only compatible with the Astro® 320 and the Alpha™ 100. The T 5, T 5 mini, TT 15 and TT 15 mini can be configured for operation with either handheld but cannot be tracked simultaneously by both the Astro 320 and the Alpha 100.)

You can add up to 20 total collars to the Alpha 100



Very expensive for either the handheld by itself, or even when you add the collars

For some people, the handheld could do with increased battery life

Learning to use the handheld and collars when you first get them can be a little tricky, but it’s not super complicated. It just takes familiarising yourself

You can’t turn off the collar from the handheld

You get a belt clip, but it could do with a lanyard as well for the price

The on/off button for the handheld could be less sensitive so you don’t accidentally turn it off or on when it’s in your pocket or in the storage bag 

Overall, despite the drawbacks, this has to be up there with the most comprehensive and advanced GPS tracking collars on the market
