The SportDOG FieldTrainer 425S is a compact e-collar system purpose-built for hunters and field trainers working with high-drive, strong-willed dogs that need consistent, reliable communication across open country. If you're training a pointer, setter, retriever, or any sporting dog that demands more correction power than standard collars offer, the 425S delivers 21 levels of static stimulation—more than the standard 425X—giving you the finesse to dial in exactly the right intensity for your dog's temperament and learning stage. The remote and receiver are engineered for one-handed, no-look operation, so you stay focused on reading your dog's body language and the terrain instead of fumbling with controls.
Built rugged for field use, both the transmitter and receiver are waterproof and submersible to 25 feet via DryTek technology, meaning they'll handle creek crossings, rain, and the general abuse of a hunting day. The system runs on rechargeable lithium-ion batteries that charge in two hours and deliver 50–70 hours of runtime per charge—plenty for a full season of training or a week of hunts. At just 8 pounds minimum for dog fit and with a neck size range of 5\" to 22", the 425S accommodates large dogs comfortably without bulk or weight penalty.
The 425S supports single-dog training out to 500 yards and is expandable: add optional Add-A-Dog collars to command up to three dogs from one remote. Whether you're correcting a wide-ranging pointer in open country or reinforcing obedience on a young retriever, the straightforward dial-and-button operation means faster, more precise timing—the foundation of solid training.

| Included Contact Points | Standard and long |
The system includes the remote transmitter, a receiver mounted on a 3/4" collar strap, a charging adaptor, both standard and long contact points, a lanyard, a test light tool, an operating guide, and a basic training manual.
Yes. The 425S comes set up for one dog, but you can expand to train up to three dogs by purchasing optional Add-A-Dog receiver collars. All three will respond to the single remote within its 500-yard range.
Both the remote and receiver are waterproof and submersible to 25 feet using DryTek technology, so they'll handle rain, creek crossings, and wet dog work without issue.
The 425S was designed for high-drive and stubborn dogs and offers more static stimulation levels than the 425X, giving you finer control over correction intensity for dogs that need a stronger or more varied correction scale.
