Garmin Alpha 300i GPS navigation 3.5" 20 dogs 55h

Handheld GPS for dog tracking

The Garmin Alpha 300i is a handheld GPS navigator designed for hunters and trainers who manage multiple dogs in the field. It tracks and trains up to 20 dogs simultaneously using compatible collars with a range of up to 9 miles. The 3.5-inch touchscreen displays vital metrics such as distance, speed and time. InReach satellite technology enables interactive SOS messaging and text communication via the Iridium network.

Battery life and dog capacity

A user-replaceable battery delivers 55 hours of typical use or 50 hours with InReach enabled, supporting extended trips without recharging. The system stores profiles for 250 dogs, allowing quick collar switching during a hunt. Real-time alerts notify you when a dog is treed or on point. Channel management tools let you monitor congestion and select clear frequencies to avoid interference from other devices.

Maps, groups and app connectivity

Preloaded TopoActive maps and downloadable satellite imagery provide detailed navigation across varied terrain. You can organise dogs and people into groups for easier pack management. The Garmin Explore app adds MapShare trip sharing and detailed weather reports when paired with a smartphone. Broadcast data uses unique IDs per channel, which you can update to maintain a clean signal in busy areas.
