K68 Wireless Signal & Magnetic Field Detector from SZ Vodasafe
Product Introduction:
The new-generation K68 detector is built with military-grade quality, featuring an upgraded LED display that accurately indicates signal source strength. Its intelligent detection mode-after product optimization-redefines efficiency, unveiling a new era of privacy protection to expose all infringements. Leveraging American military technology, this device is exclusively developed to detect various bugs, including car trackers, mobile spy software, wireless pinhole cameras, surveillance equipment, and casino cheating tools. It meets military/police-level detection requirements while measuring electromagnetic radiation sources to safeguard users from radiation hazards. Unlike market counterparts, K68 adopts a digital reception mode, expanding detection frequency and effectively filtering out ambient signal noise. Specifically designed for CDMA signal processing, it detects CDMA/WCDMA-based tracking locators-untraceable by conventional detectors-making it ideal for anti-eavesdropping and anti-tracking needs.

Operation Guide
RF Wireless Signal Detection
Step 1: Rotate the knob clockwise to maximum; a long "BIBI" sound indicates detection mode activation, with the LED main screen lighting up.
Step 2: Adjust the knob to the first stage (white zone on LED, levels 1-2) for standby. Signal strength is categorized into 10 levels:
White: Safe signal
Green: Suspicious signal
Yellow: Dangerous signal
Red: Locked signal source
Step 3: In strong signal environments, the pointer fluctuates, triggering buzzer alarms. Closer proximity to the source increases the pointer level (red zone at level 10 locks the target), with vibration frequency escalating to confirm detection.
Sensitivity Adjustment: Higher knob settings expand detection range. If no alarm occurs in the red zone, the signal is out of range.
Special Note: In urban areas, adjust sensitivity gradually to filter out cluttered signals.
Intelligent Detection Mode
Press the smart detection switch after powering on. The device automatically identifies, classifies, and records danger signals (strength >8) every minute. When a signal source transmits, the device alarms five times: the LED pointer stays at level 1, and the buzzer sounds continuously to indicate nearby threats. This function targets intermittent signals from sleeping trackers, hidden cameras, and GPS devices.
Magnetic Field Signal Detection
Attach the magnetic probe, power on, and press the strong magnetic detection switch. The purple indicator on the probe lights up, entering standby. When near a magnetic field source, the probe's white LED and buzzer activate, signaling magnetic suspicious items.
Camera Detection
Power on, press the camera detection switch. The rear laser scanning light flashes; use the fourth-gear frequency (fastest) to scan through the filter lens. Adjust the flicker frequency from fast to slow to locate red reflective spots-indicators of hidden wired/wireless cameras.
Vehicle Magnetic Equipment Detection
Magnetic locators often hide in car bottoms or interiors. Perform grid-based close-range scans under the vehicle, inside the cabin, or under the hood-avoid detecting through the body surface directly.
Application Scenarios
Anti-bug/tracker checks in cars, offices, and negotiation rooms.
Mobile phone eavesdropping detection (abnormal signal emissions during standby).
Electromagnetic radiation monitoring in workplaces and homes.
Privacy protection in hotels, restrooms, changing rooms, entertainment venues, and military facilities.
Cheating equipment detection in gambling settings.
Vehicle inspections for mortgage cars, used cars, and financial company assets.
