KJB Security DD3000 Cell Phone and GPS Detector Simple that can Detect cellular devices up to 30 ft away

Detected other (never found) frequencies but wouldn’t detect my own cellphone while it was on unless I was physically using the phone. But while the phone was on it wouldn’t find it inches away. Maybe that’s how it works but if someone has to have their phone in their hands being used to detect it, then you probably wouldn’t need this item.

The company I bought it from is fine.....the product itself is an overly priced, cheap piece of plastic that feels like a kids toy. The ac wall charger doesn't properly fit snugly into the unit itself....when you place the charger end receptacle into the device, the fit is "super loose" and barely makes a connection to charge properly. It had better be sitting flat on a table, or else the charging connection won't be made. This is far from a "law enforcement" grade product as it is advertised to be. Pick something less expensive to suit your needs
