Steve Says: Garmin TT25 TRACKING + TRAINING Add-on Collar
Let's talk about what's new in the new Alpha series of collars. We have two new collars: the T20, which is a tracking-only collar, and the TT25, which is both a tracking and training collar.
There are several new features in these new collars, the first one being dynamic updates. In previous generations of collars, update rates were set to a standard set time. The new collars have standard set update rates, but they also offer the option of a dynamic update rate. In an effort to conserve battery life, the dynamic update rate will decrease the frequency of updates to the handheld when the dog is motionless. This extends the battery life, giving you up to 68 hours of battery from a single charge.
The next new feature is multicolored running lights. On previous models, we've had running lights that you could control from the handheld, which allowed you to turn them on and off if your dogs were running, especially in low light conditions or at night. These new collars now give you seven different color options so you can identify your dogs in the dark by changing their light color.
These new Garmin collars allow you to change the flex bands. In the past, the flex band contained a wire going to the GPS antenna. In these new T-series collars, the flex band can be easily switched out in the field by removing just two screws, decreasing downtime.
The multicolored status light is a major upgrade on these new T-series collars. The status light flashes in the center of the collar when it's turned on, and the color indicates what your collar is doing:
Yellow: searching for GPS signal
Green: acquired GPS signal
Blue: pairing mode
Red: low battery
Having the multicolored status light makes it easier to look at your collar and tell when it's ready to use.
The TT25 and T20 come in one standard size and are smaller than previous regular collars. (Garmin does not offer MINI and regular sizes of these.) They are sized so they will fit most dogs really well. It's not so small that it's going to be a problem on a large dog, yet it's not so big it's going to cause a problem with smaller beagles.
Automatic WiFi updates are a great new feature. You can sync the collars to your home WiFi network using your Alpha 300 handheld, and when you put the collars on the charger, they will go online and check to see if there are any updates. Then, they automatically install the new updates. This will save you a lot of time and keep you from wondering if there's a new update.
The mini 25TT met and exceeded all my expectations. At first, I was a little bit concerned of the new design, but after a few hunts came to realize The mini 25 TT is built for the smaller hunting dogs, and I could see the performance within my pups, not having the saggy heavy head from the bigger models
Pros
Better design
EZ set up
Durable components
Adjustable for small dogs (Pointing dogs, vizslas
Cons
Antenna,is still a little too long
The new charging components do not match the older ones
Only came with a charging cord, not a plug

Garmin has been listening
May 2, 2025
They have dealt with my peeves from the older model collars! and come up with some new stuff that is handy .... This one hasn't seen a whole lot of use yet. I've owned a lot of Garmin tracking collars from the T-10 to this one , all have worked well but these newer models have a bit extra that is nice to have . In the past I've used their collars for Hounds but this one is being used for a retriever and so far so good, water doesn't seem to bother it and it has been in the water a lot on a young dog that is hard on everything and doesn't believe in avoiding objects in her way . As I said so far it seems to be working just fine and I already know from past experience that Garmin stands behind their products so no worries there ..
Pros
A little smaller and lighter which is good as it is being used on a smaller sized retriever. Went with the short piece for the GPS and that helps it fit better , Like the new antenna clips but wonder how well they will hold up..
Cons
Haven't run into any real cons with it yet

I really like the product. I bought this for a small German Short Haired pointer. I got the extended life battery which is pretty large. If I purchased it again, I would just get the normal size battery.I really like the shorter transmitter for my small dog.

January 11, 2025
Collar works great like the older versions of Garmin collars. It is configured a bit different from the older collars, the on/off button is in a different place. It isn't a problem just have to remind myself every now and then as I put collars on three dogs, two old style and this newer one
Pros
The mini obviously fits my smaller dog better than the regular sized ones

TT25 Mini Great Product!
December 23, 2024
The Garmin TT25 is a great product! The Mini is phenomenal if you have beagles, especially for smaller beagles. The regular TT25 is just a little too big for our beagles. Unfortunately we ordered a number of these before I became aware of the Minis. We are selling our regular TT25s and transferring over to the Minis. I also highly recommend the 3/4' replacement collars instead of the 1' collar that comes with them. Again, much better with the beagles. Sometimes you can get these smaller collars as a package with the Minis.
Pros
Much better fit for beagles.
Cons
The Minis should automatically come with the 3/4

Perfect Fit & Function for my 50-60lb Drahthaars
November 26, 2024
My Deutsch Drahthaars are 50 and 60lbs with smaller necks so I decided to try the Mini TT25 collars to ensure they fit well. The collars fit both dogs well! I only had room to attach two of the antennae clips to each collar, but even with the antennae hanging lower than ideal, the collars still work. I like all of the color options for the straps. It's very easy to tell my dogs apart in the field with the very different colors I selected. These collars work great with my Alpha 300i remote.
Pros
Lightweight, lots of sizing options, and lots of functionality options
Cons
Looking forward to the next generation of collars when they are even lighter in weight but still have similar or better battery power

TT25 mini
August 15, 2024
I like the wifi update of firmware and software, collar size is very similar to my TT15 mini's, it connects quickly. The reason it didn't get a 5 star, and I realize this is pretty minor, but they placed the antenna on the opposite side compared to all of my TT15 mini collars. Kinda a pain when placing the collar on the dog since it is the opposite of my TT15 minis.

GarminTT25 Tracking Collar
July 23, 2024
I previously purchased the Pro 550 Plus training and TT25 tracking system. My Griffon loves to hunt in heavy cover and tall grass and this system lets me see where and what she is doing. I now have a four month old Pudelpointer that I am training and will be using the new TT25 collar for training and hunting with both dogs. I am very happy with the system and will be able to monitor both dogs at the same time with one devise.
Pros
Easy to use and able to use the system on multiple hunts without needing to recharge.
Only needing to have one controller for both dogs.
Cons
None...have had the first system for three years with no problems.

has a learning curve on how to use. directions on how to use could be better.That being said it will let you know where you dog is at all times.
Pros
works like they say and lets you know where you do is.
Cons
hard to operate
a little touchy on the screen and changes modes too easy
when hunting in ruff cover it will change modes and i have to reset.

Functionality of this unit is absolutely amazing. Use it on a daily basis from the GPS tracking feature, to the Geo-Fence and bark collar it is amazing as long as it's working. Unfortunately, I also know that their customer service is top-notch as the first collar stopped charging after two months. They did send me a new one with about a two week turnaround time. Hopefully this one holds up because this was an expensive investment.
Pros
Loaded with features. Extremely valuable tool for any dog that ranges outside of your sideline. Several helpful tools for day-to-day training and Dog management. Geofence, point notifications, and bark collar are great additions to the tracking and training features. Battery life is impressive. When we are out camping/hunting in the field, I can easily get two full days worth of use out of one charge. When we

Works as represented. Wish Garmin would update it's GPS plug style. The tracking collar has made a big difference in my hunting
July 21, 2024
I'm hard of hearing and even with hearing aids I had difficulty keeping up with my dog with a beeper collar. The Garmin changed that. A suggested improvement would be an optional tone to sound until silenced when the system senses a point. It can be easy to miss the short vibration and the "stop sign".

550 pro plus and TT25
July 20, 2024
Started out training pups with the 550 pro and TT10's. Quickly found out that I needed to be able to track these boys because their no pant huggers. I love the Range of stimulation, the ease of use while training/hunting, and value of the 550 so I upgraded to the 550 Pro Plus. I went with the TT25 collars for all the reasons they advertise. Awesome range and battery life and locating on point. I wouldn't think of switching. At least until Garmin comes out with product better than this.

Disclaimer: The TT25 paired with the Alpha 300i is my first track and train combo, so I can't offer any comparison to older models or brands. The combo has really exceeded all expectations. I couldn't imagine hunting without it now. As always, customer service from Gundog supply was top notch.
