Very capable, complex
November 22, 2021
Works great! With all the capability comes complexity. But once setup it works very well.
ProsVery capable, lots of features, tracks dog well!
ConsHave had some difficulty accessing some features quickly. Maybe will get easier as I become more familiar with menus.

This is a great product for tracking my dog as well as communicating via tone, vibrate or stim if needed. The collar and hand held is easy to use.

Garmin Alpha 100 for pointers
October 31, 2021
Purchased this product to for upland bird hunting in Woodcock and grouse cover in Vermont and New Hampshire with my Wire hair. Also for pheasant and quail hunting during the winter months in Oklahoma and Kansas. Takes away the worry of where my dog is in reference to roads . In new covers the map is most helpful in locating terrain and locating rivers for guiding best areas and routes to take while hunting.
ProsExceptional accuracy in heavy cover. Terrain and map visuals are outstanding. Directions for set up are clear and concise.
ConsOn point sound or vibrate indication is too brief. Does not always alert when I can see dog is on point. I still need to use beeper collar to indicate dog pointing.

Good quality. Locates the satellites fast. I was concerned that the interface would be complicated, but after initial set up its not really any more difficult to use than the Pro550. My setter got away from me a couple of times which scared me to the point of getting the GPS collar. He's much happier now because I'm more comfortable letting him range without calling him back.

I love it
June 29, 2021
I tossed around the idea of getting this for a few months before I actually did and even though the price tag stings at first, I’m really glad I made the leap. They connect quickly and easily without any issues and I love all the features of the handheld. Keeping training records of my dog are really easy. Time, distance and average speed are all quickly accessed. It’s great for seeing exactly how hard my pup is working and I get a much better feel for when to give her a rest day or two. Lots of options for stimulation level and it’s a snap to change on the fly. The pointing/treed alerts are great and have worked every time, I’m yet to get a false alert when she just pauses before getting back at it. Like all the alerts there is an option for beep, vibrate, both or off making it all truly customizable. The bag it comes with is excellent, it really shows Garmin was thinking ahead when they made it. Tons of storage for all the charging cords and dang near anything else I want. A towel, booties, dog first aid kit, water bottles, kibble/treats (in a container), harness and there’s still room for several other collars and handhelds. Genius. I have no regrets about this and would buy again in a heartbeat. And of course Gun Dog Supply ships out fast and customer service is above and beyond.
ProsLightweight User friendly Durable Touch screen Works as advertised
ConsNone so far

Remarkable device but
June 22, 2021
could be better.
ProsIt has enabled me to train too bright, active rescue bird dogs who had not been trained. Could not have done it without the Alpha 100 system. Thank you!
ConsThe charging plug is clumsy, partially blocked by the waterproofing cover, and easily broken. $200. Twice. There is no way to attach a lanyard. The only attachments provided are on the battery cover, which is easily removed. You could come out of the brush with an $800 battery cover.

VERY poorly designed and made. It is not durable
June 6, 2021
I've had the Alpha 100 for almost three years. The screen lasts about a year and then dies. After sending mine back to Garmin twice and PAYING them to replace it, the third one just died so the entire 3 dog system I have is now useless. Garmin does not stand behind their product and they've wasted more than $1000 of my money. Even when the system was functional it was horribly designed. The touch screen on any field unit is a horrible idea. The collars are also falling apart.

Great tracking and training collar, very easy to get started on. I still am trying figure everything out with it mostly how to download the map so I can see ground my dog has covered.
Merchant Response:Chet, Just give us a call at 1-800-624-6378 or email us at with any questions and one of our Product Specialists will be happy to help. Thanks, Ben

By Matt
Its awesome!
January 15, 2021
Zero complaints with this system. I upgraded from a 220/DC30 system and haven’t regretted it. The biggest flaw with the system for me is it has made me a lazy hunter per say lol. I definitely don’t like hunting without it.

Set-Up Difficult
December 26, 2020
I think I will ultimately be happy with the Garmin Alpha 100/TT15, but not without a lot of initial grief. I've spent a couple of long evenings preparing the physical and electronic component features of the collar and transmitter, and two days in the field and 3-4 hours on YouTube trying to figure out the system. The instruction booklet is extremely difficult to read and is incomplete. The diagrams and print are very small and the labeling is imprecise. The booklet should have larger diagrams and detailed step-by-step instructions. The first day in the field, three of us struggled for an hour to get the transmitter to follow the dog collar. Then someone mistakenly entered a way point that linked to the transmitter. The transmitter was no longer following the dog. After hunting a corn field and risking losing my dog, I had to clear everything out and start all over. The second time hunting, the GPS linkage finally worked OK. I rigged up a lanyard to carry the transmitter around my neck. (The instructions said there is a lanyard connection, but no instructions. My previous e-collars contained a lanyard attached to the transmitter, the Garmin did not). Every time I let the transmitter hang on my neck, the touchscreen would inadvertently contact my call-whistle, or a button, or my shirt, or chest, and open another function. Sometimes it would open an entry screen and each touch would enter a different letter or character. Then, every time I tried to located the dog, I had to undo the inadvertent touchscreen entries. After returning home, and watching a YouTube troubleshooting video, I discovered how to lock the screen. Even after locking the screen, when there is an inadvertent touch, I still have to back out of the entry denial screen to locate the dog. These are significant distractions from hunting. It would be nice if the transmitter would just stay on the GPS compass locator when selected. As stated in the beginning, maybe when I get past the learning curve, I will be satisfied. Too early to tell.

Garmin Alpha 100 w/TT15
December 24, 2020
Great combination. I’m new to owning a hunting dog and first one I’ve ever trained. I’ve used the ecollar portion very little this far, but love looking at the tracks my dog takes and how he ends up hunting depending upon conditions. Waterproofness has been as advertised.
ProsQuality Ease of use Durability Garmin name

December 19, 2020
I am very happy with this purchase. I don't know if I really need this nice of a unit but I rather have and not need than need and not have. Have been on a few hints so far where my pup was on birds but I couldn't see him so the GPS which was my main reason for the purchase really came in handy. I have a pro 550 also which is also a good unit and also gets used mostly in places I'm really familiar with.
ProsGPS, expandability
ConsWish it came with a lanyard. Not that big of a deal but when bust through brush I constantly check to make sure the handheld unit is still on my side.

Great when it works
October 29, 2020
I have used this system for the last five years hunting chukar with my GSP. I have exchanged the handheld unit once during this period when it broke and am now on my third collar for the dog after the two previous collars ceased functioning. Durable it is not. Reliability is also less than great- can’t count the times the handheld sounded the on point alert and indicated the dog was somewhere other than where I could see her. However like many other Garmin products I have purchased over the years when this system works as promised it is great and really indispensable for finding an on point dog in the sagebrush
ProsProbably the best product available for what I need and Garmin is very responsive although the quality of the responses can vary depending on who you talk/type with
ConsCollars prone to breakage and indicated direction to dog on point can be incorrect
By tim
Really great tool for tracking and training
October 1, 2020
Have not had the Garmin a super long time yet, but I am finding it to be a super tool for bird hunting in both conifers, aspen, and beach with Grouse and in lower growth for Pheasant. I would not use it as a daily training collar that you want to use on a regular daily basis.
ProsFor hunting, always know where your dog is, where he is heading, the speed he is going, the area he is tracking. Can do this with multiple dogs as well
ConsExpensive, The normal collar is just livable for my 50 pound setter. It will fit smaller dogs, but I think the mini might be a better fit.

I purchase my Alpha 100 with TT 15 and was pleased with the ease of initial set up and use. I will be using it this fall on my started pup this fall. I look forward to the peace of mind it will give me when I’m out in the woods, I will be able to know where my pup is at all times, and make minor corrections when necessary.

second unit
September 17, 2020
Over the years I have had numerous hunting dogs, all German Shorthairs. During that time I have also used different products to help in keeping track of the dogs in field, most were some kind of beeper collar. About three or four years back I decided to try the GPS style unit and glad I did. Although they're not perfect they sure make things a lot easier. Wish I had bought this back when I had three dogs in the field almost all the time. I'm not into all the high tech stuff available with the unit but it does what I need it for, keeping track of my pointer.
By Kyle
so far so good
September 10, 2020
nice unit, relatively easy to operate. Don't be too intimidated by the interface, it isn't that hard. I haven't used it for training yet but it will probably be adequate for a casual, every day handler.
ProsLot of nice features and it is awesome to be able to monitor where your dog is by using the GPS.
ConsA lot of nice features! So that means there is a little bit of learning to do when using the unit.

Great Tracking Collar!
September 3, 2020
This a great tool for training and keeping track of your dog in the field. In my case, the north woods. Gun Dog Supply's typical great price and service sealed the deal.
ProsIt works great! The basic functions are easy to figure out and use. I sync'd it with my hunting buddy's Alpha 100. Should he or I ever lose a control unit, the other unit can help find it. Best of all we can keep track of each other if we're hunting in different parts of the woods.
ConsThere's so many features that it'll take some time to figure them all out. Some I probably won't use.

So far this unit is packed with great features not as intimidating as when first out of the box. Became easier to use as I played with it.
ProsPlenty of informational videos explaining what I didn?t understand to help get me through some operations
ConsNo real good way to secure carrying the unit would prefer a metal belt clip than the back bone they have, a bit expensive to chance loosing it. I believe I solved the problem for my self.

Garmin Alpha 100 tracking and training
July 22, 2020
I have used the Alpha 100 since it originally came out with the TT10 collar. This has been a top of the line GPS for myself and tracking my dogs. The built in ecollar has reduced the number of collars you have to put on your dog's neck and the number of handheld devices you must carry in the field. This is best best for trashbreaking and recall. I also use the handheld for every other type of hunting or outdoor adventure I may have.
Proslarge screen with multiple purpose functionality
Consnot practical for every day obedience training.

Review for Garmin Alpha 100 with TT15 COMBO (1-dog GPS System)
October 19, 2018
I have had this system for about three months. Have used it in the field for training while trying to learn the various features before hunting season. I like the tracking feature using the compass. It has many bells and whistles that I doubt I will ever use, like finding nearby restaurants. I plan on downloading better maps before going to KS. It takes a bit of getting used to, especially changing the level of correction. The only negative I have experienced is the amount of time it takes to get the collar and handheld communicating with each other. I live around a lot of trees and it doesn't seem to work too well in the trees. But my hunting will be on the plains so expect it will do fine. I would recommend it for the tracking.

October 18, 2018
Instant notification when my dog is out of site. I know immediately what the dog is up to. It eliminates the need to call the dog back because you don't know where or what is going on. My biggest fear is to lose my dog while hunting. This unit eliminates that fear. There are features in this collar I will probably never need to use. The screen is very easy to view even in bad light. I like the vibrate mode on the collar as my dog responds very well to it when activated. I have not and to not intend to use the stimulation mode and have removed the prongs and placed the plastic cover in their place. Very pleased with the collar and the fine people at Gun Dog Supply.

October 24, 2016
I was against shock collars for years but I have changed my tune. It shorten the training time greatly and does not harm the dog. I use a tone for the come command when the dog is out of sight. I use vibrate to get his attention for hand commands and I use the shock for sit and to get his attention for commands. The tracking is a great feature. It was the best training tool I have come across in 30+ years.

October 11, 2016
This product is very nice for tracking multiple dogs and making corrections in the field. I would have rated it 5 stars, but I think the feature for handeling multiple pointing dogs could be improved. Too much time is wasted if needing to increase stimulation levels. Vs the traditional dogtra or Tri tronics products, regardless of how you have the handheld setup. But if wanting to consolidate tracking and training collars into 1 this is the best on the market!
