Train your dog with the press of a button with the PetSafe 300 Yard Remote Trainer. This rechargeable, waterproof system was designed for dogs that might need a milder static stimulation than one of our standard systems. It comes with three different types of stimulation: tone, vibration and 1-15 levels of static stimulation (with safety lock feature for 8-15). The backlit, digital remote is easy to read and features a convenient two button design with dedicated buttons for tone and stimulation. This makes it easy to use as a vibration or tone trainer. It is lightweight and ergonomically designed to fit dogs 8 lb. and up with neck sizes up to 28in. Train up to two dogs at once with the purchase of additional collars; PetSafe Add-A-Dog Lite Receiver Collar PAC00-16163 or Add-A-Dog Receiver Collar PAC00-16164.
