Which Handheld, Collar, and Beeper Combo Fits Your Hunting Dog?
Shopping for a GPS dog tracking and training system means making a few separate decisions: which handheld to buy, which collar to pair it with, and whether you want an audible beeper added on. The handheld decision is between the Garmin PRO 550 Plus, the Garmin Alpha 300, and the Garmin Alpha 300i. The collar decision is between the Alpha T20 (tracking only) and the Alpha TT25 (tracking and training). And for hunters working heavy cover, there's a beeper battery pack that adds audible run and point alerts to either collar. This guide walks through all three decisions, with the real pros and cons of each option and which combination fits your kind of hunting, whether that's sharptail grouse country, partridge fields, quail cover, or pheasant habitat.
Quick Answer
- Want the simplest, most affordable handheld? PRO 550 Plus
- Want the most capable all-around tracking and training handheld? Alpha 300
- Hunt remote areas with no cell service? Alpha 300i
- Need to train, not just track? Pair any handheld with the TT25 collar
- Just need to know where your dog is? Pair any handheld with the T20 collar
- Want to hear your dog without watching a screen? Add the Beeper Battery Pack to either collar
Three Decisions, Not One: Handheld, Collar, and Beeper
All three handhelds in this comparison are compatible with both the TT25 and T20 collars, so your handheld choice and your collar choice are independent of each other. The handheld determines how you see and interact with your dog's location and training controls. The collar determines whether you can deliver stimulation, tone, and vibration cues, or only track location. And the optional beeper battery pack, covered further down, adds audible feedback to either collar. We'll cover the handhelds first, then the collar decision, then the beeper.
Garmin PRO 550 Plus
PRO 550 Plus Most Affordable
The PRO 550 Plus takes Garmin's familiar one-handed PRO Series training system and adds simple, at-a-glance GPS tracking. Rather than a full touchscreen map, you get a directional display showing which way your dog is and how far, along with point and tree alerts. It uses the same low-medium-high stimulation dial that Tri-Tronics users have relied on for years, supports up to 3 dogs, tracks at a range of more than 2 miles, and the rechargeable battery runs up to 24 hours.
Pros
- Lowest price point of the three handhelds
- Familiar, simple low-medium-high training dial if you've used Tri-Tronics before
- Truly one-handed operation, easy to use without looking down
- Floats and is rated IPX7 water resistant
Cons
- Shorter tracking range than the Alpha systems (about 2 miles vs. up to 9)
- No touchscreen or detailed mapping, just directional tracking
- Supports fewer dogs at once (up to 3)
- No satellite communication option
Garmin Alpha 300
Alpha 300 Most Capable All-Around
The Alpha 300 steps up to a 3.5-inch sunlight-readable touchscreen with real mapping, tracking up to 20 dogs at once from as far as 9 miles away with a 2.5-second update rate. It comes preloaded with TopoActive maps, supports dynamic tracking that extends battery life based on how much your dog is moving, and the handheld runs up to 55 hours on a charge. It's the natural step up from the PRO 550 Plus for upland hunters running multiple dogs or hunting big, open country.
Pros
- Tracking range up to 9 miles, far beyond the PRO 550 Plus
- Full color touchscreen with downloadable topo and satellite maps
- Tracks up to 20 dogs, useful for guides, trainers, or multi-dog households
- Dynamic tracking extends time in the field
Cons
- Significantly more expensive than the PRO 550 Plus
- Touchscreen takes more attention to operate than the PRO 550 Plus's simple dial
- No satellite messaging or SOS if you're out of cell range
Garmin Alpha 300i
Alpha 300i Best for Remote Country
The Alpha 300i is identical to the Alpha 300 in tracking and training capability, same touchscreen, same 9-mile range, same 20-dog support, with one addition: built-in inReach satellite technology. That means two-way text messaging and SOS alerts routed through the global Iridium satellite network, useful if you hunt sharptail prairie, remote quail country, or anywhere else cell service doesn't reach. The inReach features require an active subscription to use.
Pros
- Everything the Alpha 300 offers, plus satellite SOS and two-way messaging
- Genuine safety net in remote or backcountry hunting areas
- Works globally via the Iridium satellite network, not dependent on cell towers
Cons
- Highest upfront price of the three handhelds
- Requires an ongoing inReach subscription to use satellite features
- Satellite features add no value if you already hunt areas with reliable cell coverage

The Other Decision: TT25 or T20 Collar?
Whichever handheld you choose, you'll also need to decide between two Garmin collars. The Alpha TT25 is a tracking and training collar, capable of delivering 18 levels of stimulation, tone, and vibration through a compatible handheld, in addition to GPS tracking. The Alpha T20 is tracking only. It will show you exactly where your dog is, but it cannot deliver any stimulation, tone, or vibration cues, by design.
| Feature | TT25 (Track & Train) | T20 (Track Only) |
|---|---|---|
| GPS tracking | Yes, up to 9 miles | Yes, up to 9 miles |
| Stimulation, tone, vibration | Yes, 18 levels | No |
| Battery life | Up to 68 hrs standard / 136 hrs extended | Up to 68 hrs standard / 136 hrs extended |
| LED beacon lights | Yes | Yes |
| Best for | Dogs that need training cues in the field | Dogs that just need to be located |
If your dog is steady, well-trained, or you simply want peace of mind on where they are, the T20 does the job for less. If you're actively training, correcting, or working a young or green dog, the TT25 is the one you need, since it's the only one of the two that can deliver a correction at all.
A Third Option: Add a Beeper
There's a third decision worth knowing about, independent of the T20-vs-TT25 choice. Garmin sells a beeper battery pack that swaps in for the standard battery on either the T20 or the TT25, adding a built-in speaker with five selectable sounds, single beep, double beep, triple beep, low beep, and a hawk call, to indicate when your dog is running, on point, or stationary. It's audible up to 500 yards, includes the same LED beacon lights, and runs up to 78 hours in dynamic tracking mode.
This matters most for hunters working heavy cover, quail brush, grouse woods, or anywhere line of sight disappears quickly, where glancing at a handheld screen isn't practical and an audible cue tells you what your dog is doing without breaking stride. Since the beeper pack works with either collar, you can add it to a TT25 if you're still training, or to a T20 if your dog is finished and you just want the audible feedback. If you're weighing this against a traditional standalone beeper collar, our Garmin beeper collars category covers those options too.
Which Combination Fits Your Hunt?
PRO 550 Plus + TT25
If you're running a single dog, hunting closer cover like quail or pheasant where you don't need a 9-mile range, and want a system that's simple to learn before your first season with it, this combo delivers the core tracking and training functions without paying for features you may not use.
Alpha 300 + TT25
For sharptail grouse or Hungarian partridge hunters covering big, open prairie where a dog can range far out of sight, the Alpha 300's 9-mile range and full mapping give you the visibility you need. It's also the right call if you run more than a couple of dogs.
Alpha 300i + TT25
If your hunts take you into areas with no cell coverage, backcountry sharptail leases, remote public land, or anywhere a twisted ankle or a lost dog could mean real trouble, the Alpha 300i's satellite SOS is worth the added cost and subscription.
Any Handheld + T20
If your dog is steady and well past needing correction in the field, pairing any of these three handhelds with the T20 instead of the TT25 saves money while still giving you full GPS tracking.
Any Handheld + TT25
If you're still actively training, the TT25 is non-negotiable, since it's the only collar of the two that can deliver stimulation, tone, or vibration cues alongside tracking.
Any Handheld + T20 or TT25 + Beeper Pack
Hunting quail brush, grouse woods, or anywhere line of sight disappears fast? Add the beeper battery pack to either collar so you can hear your dog's status without checking a screen.
Set It Up Before the Season Starts
Whichever combination you choose, the worst time to learn a new GPS collar is opening morning. Build setup and practice time into the same conditioning window covered in our off-season conditioning plan and our hunter conditioning guide, so the system is second nature by the time your season opens.
- Charge and pair the handheld and collar at home first, and read through the basic menu so you're not learning it in the field
- Let your dog wear the collar during a few conditioning walks before using any training stimulation (if using the TT25), so the weight and fit are familiar
- Practice reading the tracking display, directional on the PRO 550 Plus, mapped on the Alpha 300 or 300i, during daylight walks, before you need to read it at a glance in heavy cover
- If you choose the Alpha 300i, activate and test your inReach subscription and send a test message well before opening day
- Download or confirm your offline maps for your hunting area if you're using an Alpha 300 or 300i, since cell service in the field is not guaranteed
- Check out Garmin accessories like holsters and spare battery packs so you're not caught without a backup mid-season
Frequently Asked Questions
What is the difference between the Garmin Alpha 300 and Alpha 300i?
The Alpha 300 and Alpha 300i have identical tracking and training capability: the same 9-mile range, same touchscreen, same support for up to 20 dogs. The only difference is that the Alpha 300i includes built-in inReach satellite technology for two-way messaging and SOS alerts, which requires an active inReach subscription to use.
What is the difference between the Garmin T20 and TT25 collars?
The TT25 is a tracking and training collar, capable of delivering 18 levels of stimulation, tone, and vibration in addition to GPS tracking. The T20 is tracking only and cannot deliver any stimulation, tone, or vibration. Both track at the same range and use the same battery options. The right choice depends on whether you need to train or correct your dog in the field, or simply need to know where they are.
Is the Garmin PRO 550 Plus good enough for hunting, or do I need an Alpha system?
The PRO 550 Plus is a fully capable tracking and training system for hunters running a smaller number of dogs in moderate-sized cover, such as quail or pheasant hunting. Hunters covering large, open country like sharptail grouse prairie, or running more than a few dogs, typically benefit from the longer range and full mapping of the Alpha 300 or 300i.
Do I need the Alpha 300i's satellite features if I already have cell service where I hunt?
No. The inReach satellite features on the Alpha 300i are primarily valuable in areas without reliable cell coverage. If you consistently hunt areas with cell service, the standard Alpha 300 offers the same tracking and training performance without the added cost of the satellite hardware or subscription.
Can I use the T20 or TT25 collar with any of these three handhelds?
Yes. Both the Alpha T20 and Alpha TT25 collars are compatible with the PRO 550 Plus, Alpha 300, and Alpha 300i handhelds. Your handheld choice and your collar choice are independent decisions.
How long do the T20 and TT25 collar batteries last?
Both collars offer similar battery life, typically up to 68 hours with the standard battery pack and up to 136 hours with the extended battery pack when using dynamic tracking.
Can I add a beeper to a Garmin T20 or TT25 collar?
Yes. Garmin's beeper battery pack works with both the T20 and TT25 collars, replacing the standard battery and adding a built-in speaker with five selectable sounds (single beep, double beep, triple beep, low beep, and hawk) audible up to 500 yards. It's a popular addition for upland hunters working heavy cover where checking a handheld screen isn't practical.

The Bottom Line
All three Garmin handhelds will track your dog reliably, the real decision is how much range, mapping, and connectivity your hunting country requires, and separately, whether your dog needs training cues in the field or just needs to be found. Budget-minded hunters in moderate cover do well with the PRO 550 Plus. Hunters covering big, open ground or running multiple dogs get the most out of the Alpha 300. Hunters who push into truly remote, cell-service-free country get real peace of mind from the Alpha 300i's satellite SOS. Whichever handheld you choose, pair it with the TT25 if you're still training, or the T20 if your dog is past needing correction, and if you hunt heavy cover where you can't always see your dog, the beeper battery pack adds one more layer of awareness to either collar.
