GPS With Radio Communication

These collars use GPS to locate the dog combined with radio transmission to send the signal to your receiver.

The RoamEO uses WAAS-GPS combined with radio transmission to track one or two dogs wearing transmitter collars. When powered on, the pet collar sends its GPS coordinates directly to the handheld receiver by way of a radio transmitter. This means it will send a signal to your transmitter even in areas in which there is no cell phone coverage (the GPS locator function still operates without cell phone coverage).

Cost:$154 for the complete set for one dog. $129 for additional collars.
Subscription fee: $0
Range: 500-acre diameter (1/2 mile radius); possibly less in hilly areas.
Transmitter size and weight:Transmitter comes as part of collar, which adjusts from 12 to 24 inches. Total weight is 6.5 ounces.
Battery life:24 hours of continuous use.
Pluses:No monthly fees. Does not depend on cell phone coverage. Covers two dogs.
Minuses:Limited range. No boundary alerts. Heavy and not as aesthetically pleasing as others. Collar transmitter must be powered on to transmit. Battery must be switched out every day.

Garmin offers a variety of GPS collars intended for hunting dogs that combine GPS with portable invisible boundaries, training features, and capability for tracking up to 10 dogs.

Like the RomEO, they don't depend on cell phone providers and subscriptions, but send a signal directly to a hand-held unit.

Some have a range as far as nine miles. But they are pricey, ranging from $499.99 to $799.99 for one dog.
