SportDog SD-425XS FieldTrainer

Specially designed for stubborn, high-drive dogs, the SportDOG FieldTrainer 425XS offers a higher stimulation range than the SD-425X. It features a small, lightweight design and a range of up to 500 yards. With 21 levels of static stimulation, vibration, and tone, you'll have the ability to customize your training to meet the exact needs of your dog. 

The SD-425XS is designed for dogs 8 pounds or bigger, with minimum neck size of 5 inches to a maximum of 22 inches. DryTek® technology makes it fully waterproof and submersible to 25ft. The 2-hour rapid-charge lithium-ion batteries are user-replaceable and last 50 to 70 hours on a full charge. The low-battery indicator on the transmitter and receiver let you know when its time to charge your batteries, so you're never caught without a working e-collar when you need it.

The simple design makes it easy to operate the transmitter without looking at it, so you can concentrate on your dog instead of on your equipment. Simply move the dial slightly and push the button to deliver the exact type of stimulation needed at the ideal moment. 

With the purchase of Add-A-Dog® collars, you can expand the SD-425XS for use with up to three dogs at once. These additional collars are compatible with any of the 425 models.
