Steve Says: Garmin T20 TRACKING ONLY 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.
Easy to setup and use. I had an older model Collar and decided to upgrade to the T20.

Good Performance So Far with Occasional Handheld Connection Issues
November 26, 2024
I have used the collar a handful of times and performance appears good. That said, time will tell how good. I have had some connection issues with my Alpha 200i which have been resolved by rebooting the collar, the handheld or both and I had one instance where I had to remove and re-add the collar to my 200i to get it to connect. Once the collar is connected, it seems to stay connected to the handheld.Ironically, I hunted with a friend one day who was also having connection difficulties with another Garmin system at the same time as me--but he was using completely different Garmin products. I don't think he ever got it resolved.
Pros
Good, trouble-free tracking.
Cons
Intermittent connection issues with a known working 200i.
