The Garmin Alpha 300i handheld pairs with the TT25 collar to track and train up to 20 dogs at once. A 3.5 inch touchscreen and six-button layout give quick access to maps and dog data. InReach satellite messaging adds two-way communication beyond mobile coverage. The bundle suits hunters who run multiple hounds and need reliable off-grid contact.

250-dog database and 9-mile range

The system stores profiles for 250 dogs so collars can be swapped in the field without re-entry. VHF transmission reaches up to 9 miles when paired with a compatible handheld. Location updates arrive as often as every 2.5 seconds. Multi-GNSS reception, a 3-axis compass and barometric altimeter support navigation, while channel management avoids local interference.

The bundled TT25 collar carries a top-mounted high-sensitivity GPS and Galileo receiver in a slim, rugged housing. Its user-replaceable battery lasts up to 55 hours per charge. Universal sizing fits a wide range of breeds without extra straps. Replaceable components extend the collar’s service life, reducing long-term cost for active packs.

Questions about this item

Will the Alpha 300i handheld track my older Garmin collars alongside the new TT25?

The handheld monitors up to 20 dogs using compatible collars and stores info for 250 dogs, so older supported collars can be paired and switched in the field.

How can I confirm the TT25 collar is transmitting correctly after I turn it on?

The collar updates its GPS location as frequently as every 2.5 seconds and broadcasts over VHF up to 9 miles; the handheld shows real-time position and channel ID on the 3.5-inch touchscreen.

Does the package include everything needed to start tracking, or do I need extra collars or antennas?

The box contains the Alpha 300i handheld with inReach and one Alpha TT25 collar; additional compatible collars for more dogs must be purchased separately.
