Description

PRECISION BREAKER IDENTIFICATION: Quickly and accurately locate the correct circuit breaker or fuse without turning off power. Ideal for labeling residential or industrial electrical panels.

TWO-PASS CALIBRATION TECHNOLOGY: To ensure 100% accuracy, scan all breakers once to calibrate sensitivity, then scan a second time to pinpoint the specific circuit. (Prevents "incorrect" or "multiple" breaker signals).

INTEGRATED GFCI TESTER: The transmitter acts as a professional-grade outlet tester. It detects common wiring faults (Open Ground, Open Neutral, Reverse Polarity) and includes a dedicated GFCI trip button to test safety outlets.

SENSITIVITY ADJUSTMENT: Features a variable sensitivity dial on the receiver, allowing you to fine-tune the signal to eliminate "ghost" chirps caused by electrical noise in crowded panels.

READY OUT OF THE BOX: Includes a 9V battery and a rugged receiver/transmitter set. Pro-Tip: If the unit does not beep, ensure the 9V battery is snapped firmly into the terminal clips and the battery cover is locked.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $13 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Extech products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
