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. This allows you to customize your transmitter to your training needs. You are also able to transform your one dog system at any time into a two or three dog system using the "Add-A-Dog" feature.
