Transmitter, Collar and Settings

Adjustable Boundary

You adjust the boundary distance on the transmitter itself. Set a smaller area for a small yard, or extend it when you want your dog to have more room.

Plug-and-Play Setup

The transmitter plugs in and runs without tools or technical steps. Mounting screws are included if you want to fix it in place, and a manual walks you through the setup.

TrailKeeper

Three Intensity Settings

The receiver collar has three intensity settings. You can pick the one that suits your dog's size and temperament, and begin training on the gentlest level.

Outdoor-Ready Housing

The housing is designed for outdoor use, where rain, heat and active play are part of the routine. The transmitter also has a power-saving mode when inactive and a backup power feature.
