8 Best Circuit Breaker Finders

Best Basic Circuit Breaker Finder

Klein is a big name in electrical, and the affordable Klein ET300 circuit breaker finder doesn’t disappoint. For about $30, this popular model calibrates quickly and emits a clear, loud tone and flashing light when it finds the right breaker. The ET300’s transmitter works up to 1,000 feet from the panel, too, making it a standout in this price range.

This rugged product features an auto-off feature to conserve battery life. The ET300’s two-year warranty is better than similarly-priced models from other manufacturers.
