Chord uses location and movement data to keep your pet safe within boundaries that you can set and move. Chord guides you step by step to teach your pet to remain within the boundaries as directed by the collar, giving confidence that your pet is safe, and peace of mind that they are healthy.
The Chord collar determines your pet’s location and movement by combining data from GPS, inertial, WiFi and other communications signals, and optionally from time differencing beacon stations. Your options are endless for creating boundaries wherever your pet goes.
As described on our training page, Chord guides you to train your pet to respond to sound and vibration cues from the collar. Chord uses no electric shock, ever. Chord coaches you to train your pet to respond to your commands and then Chord watches, guides, and rewards your pet, even when you are not around.
The traditional invisible fence that you may be familiar with is usually a wire buried along the perimeter of a property. The traditional invisible fence collar usually provides a vibration when the pet approaches the wire and an electric shock when the pet crosses the wire. The shock is a negative reinforcement technique. The pet learns that something bad happens when the cross a line and they learn not to do it.
Problems with the traditional invisible shock fence:
While not always practical, real fences are more humane, but they are by no means perfect. Even with proper upkeep, fences fail when gates are left open, and the occasional blizzard can create snow drift escape ramps.
Negative reinforcement is no better at keeping your pet inside an invisible boundary than positive reinforcement. Real fences are not perfect either. Chord’s approach to teach your pet to always and instantly respond to your commands is something that they feel good about. Chord then places a virtual you in your pet’s collar at all times to keep your pet where safe and abiding by your rules.
Here is how it works. As your pet approaches a boundary, your pet’s name or other cue is used to get its attention and break its concentration from whatever is causing it to wander. Your pet is then given a command that it knows is good such as “sit”, or “return”. Your pet is programmed to listen because they know from experience that when they listen, good things happen. This is the same path, yet polar opposite approach of the shock fence where when they don't listen, bad things happen. When your pet responds appropriately to commands from Chord, they hear and feel the mark of positive reinforcement such as “yes” or “good girl” as a reward to them.
If for some reason your pet leaves the boundary you have established, Chord continues to direct your pet back to where it should be. Completely opposite of the traditional invisible shock fence, your pet has incentive to return to please you and be rewarded. Chord continues to know the precise location of your pet as the wander, continues to direct your pet back, and can contact you. If your pet manages to exceed the direct communication range back to you, Chord also includes a free lost pet finding capability.
