W227 Underground Electric Dog Fence System
Main Features:
- Pulsed proportional stimulus: The closer your dog gets to the boundary, the more intense the shock will be.
- Progressive tone stimulus: A warning tone will be issued first, then a shock stimulus if your dog continues to move closer to the boundary.
- Variable field width control: Allows you to precisely control the width of the signal field.
- Audible and visual wire break indicators: Should your buried wire ever break, a loud sonic alarm will sound accompanied by a flashing light.
- Speed detect anti-run through: The faster your dog is moving, the quicker the higher level of intensity is issued.
- Built-in lightning protection: Protects transmitter from power surges caused by lightning strikes.
- This system will help teach dogs what the safe playing boundaries are, and will keep your dog from dangerous areas like roads, pools, or off-limits zones like neighbors' gardens, flowerbeds, etc.
