V90 RF Signal Detector

1. Why needs our V90 ?

It is a new measuring device which can be successfully used by engineers or counter surveillance specialists as a reliable tool for tracing different digital transmissions such as GSM, Wi-Fi, Bluetooth, etc. New methods of “listening and watching” with the help of modern technologies has become widely spread in our times. Modern GPS Trackers use the GSM and 3G cellular networks for transmitting the GPS coordinates of a car. A lot of tiny hidden cameras use Wi-Fi for sending the video.And perhaps more importantly the Bluetooth protocol has been specially designed to transmit voices or conversations with high quality at a distance of up to 100 m it can easily be used for bugging. Our V90 is your best choice.

4. How to work?

•The device is handheld: the left side of the top is the antenna, and the middle is the magnetic probe. The right side is the sensitivity adjustment knob: turn clockwise to increase sensitivity and counterclockwise to decrease it.

•Power Button (Power Switch)

a.Short press: The LED indicator will display the battery level once. Red segment indicates low battery (10%~30%), yellow segment indicates medium battery (30%~70%), and green segment indicates high battery (70%~100%).

b.Long press for 3 seconds to power on/off. After power-on, the Battery indicator shows green when the battery is normal and red when low (prompting charging).

•RF/MAG Button

c.After power-on, the device defaults to RF detection mode: the ANT-RF indicator lights up, detecting GPS, GSM, 3G, 4G, 5G, WIFI, Bluetooth, walkie-talkies, 2.4G, and RF signal bands.

d.Short press the RF/MAG Key. The ANT-MAG indicator lights up. When the magnetic Antenna is installed, the top of the probe shows a bluelight; when a magnetic field is detected, it turns white and the device alarms

•MODE Button

The device defaults to buzzer alarm mode after power-on. Short press once to switch to vibration mute mode

After power-on, short press to activate vibration detection mode. Guided by the 17-level signal indicator, adjust the vibration sensitivity via the knob (17 full bars for maximum sensitivity, 1 bar for minimum). After setting, place the device still for 5 seconds—all indicators will turn off automatically, and the device enters formal vibration alarm mode. If moved or impacted, it emits an alarm (short press VIB SOS to reset and re-enter detection mode; the alarm automatically resets after 3 minutes). Designed with low power consumption, the device can standby for up to 6 months in vibration detection mode.

•The 17-level LED signal strength indicator shows signal intensity from weak to strong: 6 green levels (low), 6 yellow levels (medium), and 5 red levels (high). An alarm or vibration is triggered when the signal reaches the 13th red level.

•The bottom features a Type-C charging port. During charging, the Battery indicator flashes red; when fully charged, it stays green.
