## Overview

The KJB Security DD3000 is a portable cellular and GPS detector designed to identify transmitting devices within a 30-foot radius.

While marketed for professional use, user feedback highlights some limitations in detection sensitivity and build quality.

## Description

This counter surveillance device is ideal for tracking down regular or concealed GSM mobile devices. Find and detect concealed transmitting cellular devices quickly and easily in GSM, CDMA, and WCDMA transmission ranges.

Review: Didn’t work as intended - 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.
Review: The company I bought it from is fine.. - 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
