Expand your Dogtra EDGE to a 2-dog, 3-dog or 4-dog system with this extra collar/receiver.
This unit can also be used to replace a lost receiver.
Equipped with high intensity LED location lights, you are able to easily find and distinguish between dogs in low-light/dark conditions. Light options are white, red, blue and green. These “location light” colors correspond to the button colors on the handheld transmitter.
Fully waterproof.
The 2-hour rapid charge Lithium Polymer batteries are housed in a separate compartment for easy replacement.
The standard 5/8″ contact points can be extended to 3/4″ for use with dogs with longer coats.
