SportDog SD-425X FieldTrainer

With a range of up to 500 yards, the SportDOG FieldTrainer 425X is the lightest and smallest e-collar in this collection. It's ideal for field training or for hunting with close-working dogs. Since no two dogs are exactly alike, the 21 levels of static stimulation allow for customized training options. 

The SD-425X is made for dogs 8 pounds or larger, with neck sizes between 5 and 22 inches. It features DryTek® technology and is waterproof and submersible up to 25 feet. The rechargeable lithium-ion batteries are ready in two hours and last 50 to 70 hours per charge. The low-battery indicator will help ensure you're never caught short when you need it.

This model's easy-to-operate transmitter allows you to deliver the perfect timing and consistency that are necessary for this type of training. Simply move the dial and push the button to deliver a tone, vibration, or stimulation. This no-look design gives you the ability to focus on your dog instead of your equipment.

The SportDOG FieldTrainer 425X is also expandable so you can train up to three dogs at once. This requires the purchase of Add-A-Dog® collars which work with any of the 425 models.
