Sportdog Field Trainer PSSD-400 Sportdog SD-400 Overview: New from SportDog , the Sportdog FieldTrainer SD-400 is an incredibly versatile training collar and a good choice for all-around use. The 400 can be expanded to control up to three dogs by adding SportDOG Brand Add-A-Dog collars. The comfortable "soft coat" transmitter finish makes this unit a pleasure to handle. This is the dog training gear the way you would design it. The low continuous stimulation levels and gradual increases between levels on the SD-400 are particularly useful with sensitive dogs or breeds. You can customize your Sportdog FieldTrainer SD-400 to match your training preference. It comes set up in MODE-1 (an 8-level continuous + 8-level momentary stimulation one dog collar with a non-stimulation tone button), but it can easily be changed into 7 different modes with different button configurations.
