How it works

The system uses a two part setup with signal injection: a transmitter plugs into an outlet or fixture, while a receiver scans the breaker panel to locate the right breaker. In three simple steps you move from outlet to panel with minimal guesswork and no manual dial adjustments.

• Transmitter and receiver deliver fast, reliable identification
• Designed for intuitive use and reduced misidentification risk
• No tuning required; just plug in and follow the cues

Visual and audible cues

The transmitter shows a bright color display with green and red indicators, while the receiver provides an analog style bar and audible alerts. Together they help you confirm results at a glance and by sound, even in dim lighting or busy environments.

• Bright display on the transmitter for quick status
