Handheld GPS for multi-dog tracking

The Garmin Alpha 300 is a dedicated GPS navigator built for hunters and handlers who run up to 20 dogs at once. It pairs with the included Alpha T20 collar to deliver real-time location data over a dedicated VHF link. The 3.5″ touchscreen and six-button layout keep controls accessible while wearing gloves. Stored profiles for 250 dogs make collar swaps quick in the field.

Battery life and signal management

A user-replaceable cell powers the handheld for up to 55 hours between charges. The collar transmits position updates as often as every 2.5 seconds using its top-mounted GPS and Galileo receiver. Channel View lets you scan local radio congestion and pick a clear ID so multiple packs do not interfere with each other. The system maintains a usable link out to 9 miles in open terrain.

Preloaded maps and hunt organisation

Downloaded satellite imagery adds terrain detail to the base map for better route planning. Dogs and people can be grouped into custom hunt teams so you see only the relevant tracks on screen. Real-time alerts flag when a dog goes “treed” or “on point” without needing to watch the map constantly. The barometric altimeter and three-axis compass supplement satellite data when reception drops.

Questions about this item

How do I pair the T20 collar to the Alpha 300 handheld so it tracks on its own channel?

Power on both units, open the dog list on the 3.5″ touchscreen, add a new dog, and assign a unique ID channel; the collar then broadcasts its GPS and Galileo position on that channel every 2.5 seconds up to 9 miles.

Which parts of the Alpha 300 and T20 collar will I need to replace over time?

Both devices use user-replaceable batteries; the handheld runs up to 55 hours per charge and the collar battery is also user-replaceable for continued field use.

How many dogs can the Alpha 300 track simultaneously before the display becomes the limiting factor?

The handheld tracks up to 20 dogs at once and stores profiles for 250 dogs, so the 20-dog live-tracking limit is reached before any memory constraint.
