The F18 RF and Magnetic Detector with Flexible Probe combines RF signal scanning, a separate magnetic-field probe and an optical lens viewer. The flexible probe can be placed near a hard-to-reach area during an authorized vehicle or room check. A removable antenna supports the RF mode, while the rear viewer and LEDs are used for a manual lens search. The listed specifications include a 1 MHz–6 GHz RF range, four sensitivity levels, a 200 mAh battery and up to five hours of continuous use. Test detection distance with the signals and surroundings relevant to your work.
- Inspection methods: RF signal scan, flexible magnetic probe and optical lens check
- RF range: 1 MHz–6 GHz (supplier parameter list)
- Controls: Four adjustable sensitivity levels
- Power: 200 mAh rechargeable battery; Type-C charging; up to 5 hours listed use
Vehicle and Workspace Checks
Use the F18 in a vehicle or workspace only where you have permission to inspect. The antenna is for an RF sweep of active transmissions. Move the flexible magnetic probe near a specific area when checking for a strong magnetic source, then inspect that location physically. A displayed signal is a lead for a closer check, not identification of a particular tracker or recording device.
Probe, Controls and Signal Display
The flexible wired probe reaches around edges and other spots that are awkward for the main body. Front controls switch modes and adjust the four sensitivity levels, with a signal display below the red viewing ring. The optical viewer on the rear is a separate manual check for lens reflections. Select the relevant mode and verify the result at the suspected location.
Rear Optical Check and Power
Turn the F18 over to use the optical viewer and its surrounding LEDs when examining possible lenses. The parameter list specifies Type-C charging from a 5 V / 1 A supply and a 3.7 V, 200 mAh polymer battery. Continuous use is listed as up to five hours. Check the working time on a sample if it will be used for a long inspection shift.

Inspection Limits
The F18 supplier material quotes a detection-distance range but does not define the test signal, magnetic source or room conditions. Those figures are therefore not presented as a guaranteed working distance. An unpowered device may emit no RF signal. The magnetic probe and optical viewer are separate checks and still require a deliberate physical inspection.
Package Contents
The F18 is pictured with its antenna and flexible probe. Confirm the antenna, probe, charging cable, manual and retail box configuration with QZT for the batch you plan to order.
Ordering from QZT
Unit-price bands start at five pieces. Tell QZT the quantity, destination and required accessory or manual configuration for a current quote. Freight and duties are separate. Confirm the sample and any market-specific paperwork before production is committed.

Frequently Asked Questions
What does the flexible probe on the F18 do?
The F18 RF and Magnetic Detector with Flexible Probe uses its wired flexible probe for a separate magnetic-field check near a specific area. The antenna handles RF scanning, and the optical viewer is used to look for lens reflections. These modes do different jobs; a magnetic or RF indication should be checked at the location before drawing a conclusion.
What RF frequencies are listed for the F18?
The F18 RF and Magnetic Detector with Flexible Probe is listed for 1 MHz–6 GHz RF scanning in the supplied parameter table. That is a frequency-range specification, not a promise to find every transmitter. Source strength, shielding, mode and surroundings affect results. Test an approved sample against the signals relevant to your inspection work.
How long can the F18 work between charges?
The F18 RF and Magnetic Detector with Flexible Probe is listed with a 3.7 V, 200 mAh rechargeable battery, Type-C charging and up to five hours of continuous use. Runtime may change with the mode and alert settings. If a fixed operating shift matters to your order, check a production sample in the selected modes first.
What should be confirmed for an F18 bulk order?
The F18 RF and Magnetic Detector with Flexible Probe has quantity-price bands beginning at five pieces. The detector is pictured with an antenna and flexible probe; confirm the retail box contents for the selected batch. Tell QZT your quantity, destination, manual language and accessory requirements, then approve the sample and final quote before production.
