The DC 50 is designed to work with Garmin’s Astro 320 tracking system, and it also comes with new features such as bark detection and various training functions, as well as longer battery life and a longer stronger antenna.
The DC 50′s design was also changed to accomplish a better signal for the GPS unit. The main housing sits below the dog’s neck while a low-profile GPS antenna now sits atop the dog’s neck on the collar, like the alpha and DC 30 collars in a way. This provides a better signal for GPS satellites, and in addition to GPS, the DC 50 also supports GLONASS, which is approximately 20% faster than GPS.
You can also use both GPS and GLONASS together, which will allow the collar to lock on to 24 more satellites than when just using GPS alone. As for the antenna, it’s made out of braided steel, so it’s meant to be beaten around some and still withstand the brutality.
