It’s easy to get overwhelmed with training collars that seem to be adding more and more features. But sometimes the classics are just hard to beat. The SportDOG FieldTrainer® 425 was the first collar I ever purchased for training my very first dog. It still works flawlessly. And though I’ve added new collars with added features as I’ve gained experience and dogs, I still go back to this little workhorse again and again because it is bullet proof, water proof, mud proof, chew proof. The collar and transmitter are small yet the charge seems to last forever. It has a 500-yard range, is expandable to three dogs, and has tone and vibrate features that we use to teach dogs to hunt silent with us. It’s just an awesome all around collar with unbeatable performance at a great price.
