The compact SD-400 FieldTrainer 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 additional SportDOG SDR-FS 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.

The SD-400S offers all the features of the the SD-400, but is specially designed for tougher, more stubborn dogs.

SportDOG Brand™ is the kind of dog-training gear sportsmen would design and build for themselves if they ran the company. Because sportsmen do run the company. They understand that you don't want to read a manual in the field. The gear has to be easy to use. They know it's going to take an occasional hard knock. That's it's going to get wet. And that you want it to keep on working. Not just for a season, but for a lifetime. Guaranteed.

And delivered at a fair price. With more range for the money than anything else our there. And all of this comes with the only Lifetime Limited Warranty in its price range.
