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 ## Features - Detection Mode: RF Power Peak Detection - Detection Frequencies: GSM 880-915MHz, CDMA 824-849MHz, WCDMA (1920-1980MHz), and DCS (1710-1785MHz) - Power: Li-battery (single, 1800mAh @ 3.7VDC) - Alert: Vibration and audible - Operation Time: 18-20 hours (on a single charge) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004R6TVFI | | Additional Features | Cellular Signal Detection | | Are Batteries Included | Yes | | Battery Average Life | 18 Hours | | Brand | KJB | | Built-In Media | 1 x Remote Control | | Connectivity Technology | Cellular | | Control Method | Touch | | Customer Reviews | 1.3 1.3 out of 5 stars (2) | | Display Type | LED | | Human-Interface Input | Buttons | | Item Weight | 0.45 Pounds | | Manufacturer | KJB Security | | Map Types | Road | | Supported Satellite Navigation System | GPS | | Touch Screen Type | Resistive | | UPC | 738549222286 | ## Product Details - **Battery Life:** 18 Hours - **Brand:** KJB - **Connectivity Technology:** Cellular - **Display Type:** LED - **Human Interface Input:** Buttons - **Included Components:** 1 x Remote Control - **Item Weight:** 0.45 Pounds - **Map Type:** Road - **Special Feature:** Cellular Signal Detection - **Touch Screen Type:** Resistive ## Images ![KJB Security DD3000 Cell Phone and GPS Detector Simple that can Detect cellular devices up to 30 ft away - Image 1](https://m.media-amazon.com/images/I/41vA0AAk4zL.jpg) ## Questions & Answers **Q: will this item detect cell phones? say in a prison like setting?** A: Yes, it will detect any cell phone that is transmitting (in use). **Q: will this device detect a bug in my iPhone 3G cell phone?** A: No **Q: will it find or detect a cell phone if phone is turned off** A: No **Q: Does it detect gps trackers installed on a vehicle? by a car dealership? by a spouse?** A: It will yes as long as the GPS device is a live tracker.
