Product Key Selling Points
✅ Unmatched Full-Band Detection from 2G to 5G & Beyond The PHC3 Pro sets a new standard with its broad frequency coverage from 1MHz to 12GHz. It seamlessly scans and identifies signals from all global cellular networks (2G/3G/4G/5G), including China's major carriers and broadcast 5G. This ensures the detection of the latest 5G spy devices, GSM bugs, cellular GPS trackers, and video transmitters that cheaper detectors miss. Its ability to process TD-LTE and standby signals breaks through common market technical barriers, providing industry-leading effectiveness in real-world scenarios.
✅ Precise Wi-Fi & Bluetooth Hotspot/Tag Identification & Location Go beyond simple signal detection with intelligent analysis. The PHC3 Pro features separate, dedicated detectors for 2.4GHz bands. Its unique Wi-Fi interface not only lists hotspots but can also locate specific Wi-Fi/Bluetooth terminals and identify potential cameras (flagged in red). Crucially, it can detect and locate BLE Bluetooth tag trackers like Apple AirTag and Huawei Tag, offering vital protection against covert physical tracking stalking.
✅ 4.3" Touchscreen with Signal Logging & Forensic Analysis Operate with clarity and record evidence. The large 4.3-inch color TFT capacitive touchscreen provides an intuitive, menu-driven interface for easy navigation. The built-in signal logging function records up to 1 hour of cellular data and 24 hours of Wi-Fi/Bluetooth activity. Logs can be reviewed on-screen or exported via SD card for detailed forensic analysis and reporting on a computer, making it indispensable for professional security audits and documentation.
✅ High Sensitivity & Adjustable Audio Alert for Accurate Pinpointing Engineered for precision, the PHC3 Pro boasts high sensitivity (up to -85dBm) and a wider dynamic range, enabling the detection of weak signals from up to 50 meters away. The audio "beeping" alert mode increases in frequency as you approach the signal source, allowing for accurate spatial triangulation and pinpointing of hidden devices. The durable machined aluminum housing ensures reliability in demanding field use.
✅ Multi-Interface Operation for Targeted Sweeps Conduct efficient, targeted inspections using four specialized modes. The Communication Interface scans all cellular activity. The Wi-Fi Interface (with Router, Client, and Unconnected sub-modes) analyzes network threats. The Bluetooth Interface tracks tags and Bluetooth devices. The Quick Scan Interface provides a rapid overview of all active RF signals from 1MHz to 6GHz. This structured approach streamlines the search process for both professionals and serious privacy advocates.
