Handheld and collar tracking system

The Garmin Alpha 300i handheld and TT25 collar work together to track and train up to 20 dogs in the field. A 3.5 inch touchscreen and six-button layout give quick access to maps, alerts and dog status. Inreach satellite messaging adds two-way communication when mobile networks are absent.

Upgrade from basic radio trackers

This kit replaces older single-dog beepers or limited-range radio collars by adding satellite messaging, multi-GNSS positioning and storage for 250 dog profiles. The jump is worth it when you run multiple dogs, hunt in remote terrain or need real-time treed and on-point alerts across a pack.

VHF radio and satellite limits

Dog positions transmit over VHF up to 9 miles line of sight; terrain, vegetation and weather will reduce that range. Updates arrive as often as every 2.5 seconds, but collar battery life caps at 55 hours per charge. Channel congestion in busy areas can still cause interference despite the channel-view tool.
