SportDOG YardTrainer 300

The SportDOG YardTrainer 300 triples the range of the YardTrainer 100 while staying in the same compact, value-priced format — 300 yards of control for home yards, larger parks, and close field training scenarios. Seven levels of static stimulation, tone, and vibration, adjustable on the collar across low and medium ranges if the default doesn't suit your dog. DryTek waterproofing to 25 feet, 2-hour rechargeable batteries running 50-70 hours, single dog for dogs 8 lbs and up. The right step between the YardTrainer 100 family and the full field-range FieldTrainer 425X.
