Anonymous 5 out of 504.18.2017 at 12:00 pmI 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”.
