Garmin Alpha 100

Yes, if the price is right. The 100 does the core job every Alpha does - VHF tracking and training with no cell signal needed - and Garmin still supports it with software updates. What it lacks is the touchscreen of the 200 and 300 and the inReach satellite messaging of the i models. For a hunter who just wants to see where the dogs are and correct them, that is not a dealbreaker.

Because it is only sold used now, condition is everything. A tired battery is the most common complaint and the cheapest fix - see the batteries page before you assume a unit is worn out.

Power it on and watch for a screen that stays frozen, a battery that will not hold charge, and a charge port that no longer seats cleanly. All three are documented, fixable faults rather than reasons to walk away, and they are covered on the troubleshooting page.

Confirm which collar comes with it. A 100 bundled with a working TT 15 is worth more than the handheld alone, but a current TT 25 will also pair, so a handheld-only unit is still usable if you already have collars.

Run the latest firmware through Garmin Express - the steps for the older handheld are on the update page. A longer antenna is the single upgrade most 100 owners make, and a case or screen protector keeps the non-hardened screen from taking a hit in the truck.
