What to know before buying

Listing details to confirm

The listing is inconsistent about RF range, giving 1 MHz to 6.5 GHz in the main details and feature text but also 1 MHz to 8 GHz in one description. It also conflicts on the display wording, which is listed as LCD or LED, and on power: the details say battery powered while a description claims a rechargeable 1000 mAh battery with about 10 hours of continuous use. Treat those battery runtime and charging details as unconfirmed. The seller describes RF detection rather than a guarantee of finding every device. Strong surrounding signals can affect location accuracy, and intermittent trackers may require extended waiting.

Frequently asked questions

What signal range does the listing give for the K18?

The main details and feature text give 1 MHz to 6.5 GHz. One description also states 1 MHz to 8 GHz, so the upper range is inconsistent in the listing.

Can the K18 detect intermittent GPS trackers?

The listing says trackers may transmit at intervals, so the detector may need to remain nearby while waiting for a signal.

Can it be used without audible beeping?

The listing describes vibration mode and an earphone option for detecting RF signals without sound from the unit.

Is its battery rechargeable, and how long does it last?

A product description claims a rechargeable 1000 mAh battery and about 10 hours of continuous use, but the technical details only say battery powered. Treat the charging and runtime claims as unconfirmed.
