DOG GPS X20 is a device for locating your dogs up to 20 km away.
It consists of a transmitter that is placed on the dog's collar and a receiver (handheld device) on which the handler tracks the distance and direction to the dog's location. The transmitter obtains its location from GPS satellites and uses a radio frequency (RF) signal to transmit the location information to the handler's receiver.
DOG GPS X20 also has additional functions - compass, FENCE - acoustic boundary, which provides information about exceeding the set distance from the receiver by your dog. It also has a BEEPER function which makes it easy to determine if your dog is moving or standing still.
