2-dog version of the SD-400. Compact; ideal for training in the yard, field, or for hunting with close-running dogs.
Both the Transmitter and Receiver are waterproof and submersible. This 2-dog system has a single transmitter that controls the 2 included collar/receivers (one with orange strap and one with black strap). The comfortable "soft coat" Transmitter finish makes this unit a pleasure to handle. Dog Training Gear the way you'd design it.
