This isn't your old-school K18. The K20 Professional RF Detector is the modern successor to the industry-standard K18, re-engineered to handle the complexities of today's digital landscape. With a massive jump in sensitivity and an expanded bandwidth range, it’s designed to find the signals that older, cheaper units simply miss.

The Professional Edge: What’s New?

While older models often topped out at 6.5 GHz, the K20 pushes your detection capabilities from 1 MHz all the way to 8 GHz. This means you aren’t just looking for basic WiFi; you’re scanning for high-frequency 5G signals, modern Bluetooth bugs, and the latest digital burst transmitters that standard detectors overlook.

Core Capabilities

• Precision Wireless Signal Detection: Rapidly identifies active RF sources including wireless bugs, hidden microphones, and unauthorized signal transmitters. The adjustable sensitivity allows you to "narrow the search" to pinpoint the exact location of a device, even in high-interference areas.
• Upgraded Magnetic Field (GS) Detection: Most GPS trackers use magnetic mounts to hide under vehicles or inside upholstery. The included GS probe is specifically tuned to find these "dormant" magnets, even when the tracker isn't currently transmitting.
• Advanced Optical & Infrared Scanning:
• Infrared Laser: Uses a specialized red-light filter to catch the "glint" of a camera lens, regardless of whether the camera is on or off.
• Automatic IR Detection: Features a dedicated sensor to sniff out the invisible infrared light used by night-vision spy cameras in pitch-black environments.
• Tactical Design & Utility: Compact enough for a pocket but built for the field. The integrated high-intensity flashlight is essential for inspecting those "blind spots"—under dashboards, inside drop ceilings, or behind furniture.
