Why the K version matters in Germany
Garmin builds its K models specifically for Germany and Europe. They use a licence-free radio frequency, so no local registration is needed. US models (Alpha 300, TT25, T20 without the K) use different frequencies and are not compatible with K devices.
FAQ
Does the T 20 K work with a US Alpha 300 or TT25?
No. K collars pair with K handhelds (Alpha 300 K, 300i K, 200 K, 200i K, 10 K) and Atemos devices.
Is the T 20 K legal to use in Germany?
Yes. It is the German/EU K version on a licence-free frequency, and it is tracking only.
