The only GPS dog collar to use the top-of-the-line, active, dual-feed GPS antenna and patented True Location™  technology, SpotOn dynamically filters out inferior GPS signals affected by trees and buildings. Independently tested by a third party, SpotOn was proven to have boundary alerts that are 6x more consistent and a fence line that is 7x more accurate than the other leading GPS smart fence.TRAVEL-FRIENDLY - UNLIMITED CUSTOMIZABLE FENCES - Create wireless fences of any shape or size with no acreage limits and add Keep Out Zones to off-limits areas and correction-free zones without extra hardware or beacons. There are no buried wires or hardware to install. Make fences at home, on the go, or if you move. SpotOn is the ONLY GPS wireless dog fence to support overlapping fences, so you can create a large fence for daytime use and a smaller fence for night. Use off-grid mode for areas with no cellular connection.TRACK AND RECALL YOUR DOG WITH AN OPTIONAL SUBSCRIPTION – Real-time location tracking lets you see your dog’s location anytime, receive low battery notifications, and get alerts and escape reports if your dog leaves the fence boundary. Recall feature lets you call your dog home and activate a light on the GPS dog training collar for added visibility at night.
