KOO1100: Ships Via Small Parcel Ground
The portable base unit creates an ''forbidden'' zone of 6-10 feet. Simply attach the tag-sized transmitter to your pet's collar and when the pet enters the offlimits zone, the transmitter sends a signal to the base unit. The tone is a safe, but annoying ultrasonic tone, inaudible to humans. Repeated events will help train your pet quickly and safely. Multiple transmitters can be used with the single base unit. Additional transmitters are great for multiple-pet homes.
