The Alpha® 200 dog tracking and training handheld lets you monitor up to 20 dogs with additional dog devices sold separately from up to 9 miles away (depending on your dog device) on a 3.5” touchscreen display with a 2.5-second update rate. Easily control training functions by using the button-operated, dog-focused design. You’ll also have access to premium Garmin navigation features, such as preloaded TopoActive maps, BirdsEye Satellite Imagery with direct-to-device downloads, and built-in 3-axis compass and barometric altimeter.
