The SportDOG FieldTrainer SD-400 is ideal for training in the yard, field, or for hunting with dogs that hunt close. Both the Transmitter and Receiver are waterproof and submersible. It can be expanded to control up to 3 dogs by adding SportDOG Brand Add-A-Dog collars. The comfortable "soft coat" Transmitter finish makes this unit a pleasure to handle. Dog Training Gear the way you'd design it.

Note: For more stubborn dogs see the SportDOG FieldTrainer 400S

Proving that big performance can come in a small package, SportDOG Brand has introduced a remote-training system that puts the most-valued features of its popular e-collar line in a super-compact package. Designated as the FieldTrainer, the Model SD-400 boasts the smallest collar-receiver in its class. Also available is the Model SD-400S with a higher-output receiver for hunters who desire a training system for stubborn dogs.

The FieldTrainer excels in all training and hunting environments because its transmitter and receiver are both rugged and completely waterproof. Together, they offer control from up to 400 yards, even though their size – transmitter, 3.2 oz; receiver, 2.8 oz. – is less than half that of competing products in this category.

Like all models in SportDOG™ Brand’s growing, innovative product line, the FieldTrainer offers a long list of features and benefits that reflect the company’s dedication to living up to its philosophy of providing hunters with “The Gear You’d Design.”

The FieldTrainer’s transmitter and collar receiver each operate on a long-life, rechargeable Nickel-Metal Hydride battery for trouble-free use. Both components feature a low-battery warning light so a hunter never has to cut short a day of hunting because of a dead system.

The versatile, compact transmitter provides plenty of training options, with up to 16 levels of continuous or momentary stimulation, a tone-only button and tone with one-second delay option. The transmitter also allows the user to select one of seven different training modes, including a three-dog mode that dramatically simplifies controlling multiple dogs in the field. For two- or three-dog operation, simply purchase SportDOG Add-A-Dog™ collars as needed. The user-friendly collars are easily matched to the transmitter for instant operation.
