Sport Dog FieldTrainer 425S

The FieldTrainer® 425S takes the most advanced, industry-leading technology that SportDOG™ Brand has ever built into its e-collars and packaged it up in the most compact system ever offered.

Designed specifically for tougher, more stubborn dogs, it is ideal for training in the yard, field, or for hunting with close-working dogs.

Switch instantly between stimulation, vibration, and tone to fit the correction or communication to your dog’s temperament and learning ability.

Both the Transmitter and Receiver are waterproof and submersible. It comes as a 1-dog system, but can be expanded to control up to 3 dogs by adding SportDOG Brand Add-A-Dog™ collars.

The comfortable, ergonomic transmitter weighs only 4.0 ounces, making this unit a pleasure to handle.

This 425S Model is an upgraded replacement for the FieldTrainer 400S.
