Handheld for multi-dog tracking

The Garmin Alpha 300i handheld is built for hunters and trainers who need to monitor up to 20 dogs at once. It combines a 3.5 inch touchscreen with a six-button layout for glove-friendly operation. Inreach satellite technology adds two-way messaging when mobile coverage disappears. The system stores profiles for 250 dogs so you can swap collars quickly in the field.

Collar and channel management

The Alpha T20 collar mounts a high-sensitivity GPS and Galileo receiver on a slim, rugged strap with universal sizing. It broadcasts location updates every 2.5 seconds over VHF to the handheld at distances up to nine miles. A user-replaceable battery delivers up to 55 hours of run time. Channel View lets you scan local collar traffic and pick a clear ID to avoid interference.

Navigation sensors and app support

A built-in three-axis electronic compass and barometric altimeter supplement the GNSS receiver for reliable heading and elevation data. Downloaded satellite imagery can be added to the handheld for better terrain awareness. The app-enabled platform syncs waypoints, routes and dog data to a paired smartphone for planning and review.
