Manual sensitivity adjustment is a great feature and actually allows quicker and isolation of the breaker you’re trying to find than “automatic learning” types some competitors offer. TIP: read and follow the written directions, and hold the tip of the sensor away from the load side of the breakers and towards the bus bar side when scanning. I found this greatly reduces false signals, even at high sensitivity settings. Then gradually reduce the sensitivity until you’re getting an intermittent chirp and flashing light at one breaker, and not a constant beep and light.
