Does the TRX collar correct or train my dog?

No. It is GPS tracking only and has no stimulation or e-collar functions. Pair it with a separate training collar if you need correction.

Do I need a cellular plan to use it?

No. The collar talks to the Pathfinder app over its own radio link, and maps can be downloaded for offline use.

The Pathfinder system expands to 21 additional GPS collars and users, so several dogs can be tracked at once.

Yes. The collar is fully waterproof for use in wet and muddy conditions.

Dogtra rates it at 9 miles line of sight. Expect less in heavy cover, hills or dense timber.

A Dogtra Pathfinder handheld and the smartphone app. The collar alone does not display tracking.
