Yessir with my 320.. To me the 320 is easier to use than the 220. I bought both my t5s from Usedgarmincollars.com and I haven't lost them on gps yet and have had them well over a mile. And the DC-50s I like the bark detection but that feature only works when it wants to and 1 of em if it gets below half battery it starts losing gps signal. Like it shows the dog on the garmin still just doesn't update the location. Pisses me off
