Handheld GPS for Multi-Dog Tracking

The Garmin Alpha 300i handheld pairs with three TT25 collars to monitor up to 20 dogs at once. A 3.5 inch touchscreen and six-button layout give quick access to maps and training controls. InReach satellite messaging lets you exchange texts beyond mobile coverage. The system stores profiles for 250 dogs so you can swap collars in the field.

Three TT25 Collars Extend Range and Battery

Each collar transmits GPS and Galileo positions over VHF up to 9 miles with updates every 2.5 seconds. User-replaceable batteries deliver up to 55 hours of run time per collar. Slim, rugged construction fits dogs of all sizes and withstands rough terrain. Unique channel IDs reduce interference from other tracking devices nearby.

VHF Range and Update Rate Define Limits

The 9-mile line-of-sight range drops in heavy cover or steep valleys. Position refreshes every 2.5 seconds, so fast-moving dogs may travel several metres between updates. Satellite imagery and map downloads need a data connection before you leave the trailhead. The 1.3 inch unit width keeps the handheld pocketable but limits screen real estate for detailed cartography.

Questions about this item

How often will I need to swap the user-replaceable battery in the TT25 collars during long hunts?

Each collar runs up to 55 hours on a single charge, so plan to recharge or swap batteries after roughly two full days of continuous tracking.

What limits how many dogs I can follow at once on the Alpha 300i screen?

The handheld tracks up to 20 dogs simultaneously, and the channel view helps avoid interference when many collars are active.

How hot does the handheld get and how much power does it draw when running all day with satellite messaging?

The 3.5-inch touchscreen and inReach satellite link run on the internal battery; typical all-day use stays within the 55-hour rating without overheating.
