Anonymous 5 out of 5 04.18.2017 at 12:00 pm I purchased the Garmin Delta XC for my Jack Russell. I need a collar that was waterproof yet affordable. The collar is very easy to use. So far the tone and vibration are the only features I have to use to control my dog. In the past, my dog was having to stay in a pen or be on a leash while we were at our river place. With the collar she is able to stay loose. We call it the “freedom collar”.
