Garmin Alpha 200i handheld with T5 dog tracking collar

D2 Cloud-Optional — Full function with the router off.

The unplug test

Nothing changes about tracking your dog, because that never touched the internet. The handheld talks straight to the collar over a MURS-band radio link and draws the dog's position on its own screen; no phone, no app and no Garmin account are involved in that path, and it works in country with no cell coverage at all, which is the point of it. What you lose is the surrounding layer: syncing waypoints and tracks to the Garmin Explore app over Bluetooth, and pulling device software updates over Wi-Fi. The handheld also has Garmin's inReach satellite messaging built in, and that -- two-way text and SOS over Iridium -- needs a paid subscription and a Garmin account. That subscription gates a bolted-on satellite communicator, not the dog tracking.

Why this tier: Dog tracking, the function this product is bought for, carries no vendor cloud: the collar's FCC grant (IPH-0199715) shows a 151.82-154.6 MHz transmitter certified under Part 95J MURS -- a rule-authorised personal radio service like FRS/GMRS, where an intentional-radiator grant is expected and is not evidence of a cloud -- and Garmin's own owner's manual describes the handheld and collar communicating over a direct, line-of-sight radio link, with position shown on the handheld's own screen. A Garmin support representative states on Garmin's own forum that tracking dogs requires no inReach subscription. But the handheld is not a radio-only device, and this record was first written as though it were. Garmin's own 'Connected Features' manual page names three: Garmin Explore (waypoint/track/route sync over Bluetooth to the Explore app), inReach tracking and messaging over the Iridium satellite network, and software updates over Wi-Fi. Garmin Explore is a nameable, Garmin-operated service the handheld reaches, so the D1 row -- 'no vendor cloud endpoint' -- does not apply. Setup completes and dogs are tracked with no account and nothing connected, which is the D2 row: a vendor cloud that exists and is genuinely optional for core function.

Self-hostable partial — partly replaceable on your own hardware
Waypoints, tracks and routes sync through Garmin Explore, but the same data moves over USB as GPX files and is handled by GPSBabel, QMapShack or any GPX-aware mapping software on hardware the owner runs. What has no local replacement is inReach satellite messaging and SOS, which depends on the Iridium network and Garmin's ground service by construction. Dog tracking needs neither.

Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.
