GSM / GPS Tracker detector 1217 PLUS

The GSM/GPS Tracker Detector 1217 PLUS is a professional multiband RF detector for detecting hidden transmitters, GPS trackers, and other wireless threats. This advanced detector is designed as an anti-tracking solution for vehicles, offices, and private spaces where privacy and security are paramount. Thanks to support for modern networks such as 4G, 5G, Wi-Fi, Bluetooth, DECT, and various IoT bands, this model is suitable for detecting both classic and advanced spy devices.

Selective multiband detector with global coverage

Unlike simple broadband detectors, the 1217 PLUS operates selectively: the device scans up to 27 separate mobile and wireless bands and filters out interfering signals. This allows for much more sensitive mobile signal detection than standard RF detectors. The internal band table covers all common GSM, 3G, 4G/LTE, and 5G standards worldwide, plus Wi-Fi 2.4/5 GHz, Bluetooth, DECT, and ISM bands. You can also configure which bands are active by region (EU, US, or Total), so the detector is optimally tailored to the country you're searching in.

Detection of mobile signals, WiFi, Bluetooth and IoT

The 1217 PLUS recognizes a wide range of wireless protocols. These include GSM, CDMA, 3G, 4G/LTE, and 5G for mobile communication, as well as Wi-Fi 2.4 GHz and 5 GHz, Bluetooth, DECT, and ISM bands around 433, 868, and 915 MHz. These frequencies are widely used by GPS trackers, hidden cameras, listening devices, smart sensors, and IoT devices. Selective detection allows you to see exactly which type of signal is active, rather than just a single, aggregated RF level.

Four smart search modes: ALL BANDS, GROUP, BAND and TRACKER

The 1217 PLUS offers four search modes that work seamlessly together. In ALL BANDS mode, the detector scans all selected bands simultaneously and displays the signal strength per band group (mobile, DECT, ISM, BT/WiFi). From there, you can zoom in to GROUP to take a closer look at a single group, or to BAND to analyze a specific band in detail. In the special TRACKER mode, only mobile bands are measured and a histogram is created, making intermittent GPS trackers easier to identify. You can choose whether you want to be alerted visually, audibly, or via vibration.

TRACKER mode for GPS trackers and long-term monitoring

TRACKER mode is specifically designed for locating GPS beacons in vehicles or other mobile objects. In this mode, the 1217 PLUS only measures mobile bands and displays a histogram of the last minutes or hours. In normal speed, you see a history of approximately 6 minutes, ideal for test drives. In slow mode, the histogram can be built up over 24 hours, allowing trackers that only transmit data once per day (store and forward) to be detected. The time between signals (period time) measurement function allows you to easily identify recurring transmission intervals.

Step-by-step guide to finding a GPS tracker in a vehicle

1. Turn off your own mobile phone and other wireless equipment in the car or put it in airplane mode.
2. Choose a route with as few other vehicles and transmission sources as possible in the area, for example outside built-up areas.
3. Switch on the 1217 PLUS, select the correct region (e.g. EU) and set the alarm threshold slightly above the background level.
4. Start TRACKER mode and drive for a few minutes, watching for periodic spikes in the histogram.
5. If you notice a pattern (peaks when moving off, braking or at fixed intervals), lower the threshold and switch to GROUP/TIRE to monitor the tire(s) in question more closely.
6. Then use the tire and cluster analysis in combination with a physical inspection of the bumper, chassis, dashboard, wheel arches and hollow spaces to locate the tracker.

Professional service and band selection per region

The BANDS button allows you to easily configure which band groups (MBL1–4, DECT, ISM, BT/WiFi) should be actively scanned. You can disable entire groups or individual bands to reduce the risk of interference and increase sensitivity for specific tasks, such as Wi-Fi/Bluetooth only or mobile networks only. A joystick and clear color display allow you to quickly switch between ALL BANDS, GROUP, BAND, and TRACKER, and fine-tune alarm thresholds.

Practical applications in vehicles, offices and hotels

In vehicles, the 1217 PLUS is used to detect hidden GPS trackers, mobile transmitters, and data modems concealed under the car, in the bumper, behind upholstery, or in the dashboard. In offices and conference rooms, the detector helps check electrical outlets, ceilings, smoke detectors, lamps, and conference tables for active transmitting equipment. In hotel rooms and vacation rentals, this model also offers a quick way to determine the presence of Wi-Fi cameras, Bluetooth devices, or other RF sources.

What does the 1217 PLUS detect and what doesn't it?

The 1217 PLUS is designed to detect devices that actively emit radio frequency signals. This includes GPS trackers, mobile phones in spy mode, wireless microphones, Wi-Fi and Bluetooth cameras, DECT handsets, and IoT transmitters. Devices that are completely passive and do not generate an RF signal, such as simple voice recorders without a wireless module or disabled electronics, cannot be found. Specialized hardware that searches for semiconductor structures is required for such applications.

Working in busy urban RF environments

In urban areas and multi-tenant office buildings, there are often numerous active Wi-Fi routers, access points, mobile devices, and IoT sensors. To perform effective sweeps in such environments, it's wise to first disable known sources where possible and then temporarily deactivate unnecessary bands in the BANDS setting. By setting the alarm threshold slightly higher and monitoring only relevant band groups, it becomes easier to distinguish suspicious patterns from normal background activity.

Use within the law

Using an RF detector like the 1217 PLUS is permitted to protect your own vehicle, home, office, or business premises. However, actively scanning third-party equipment or property without permission may violate privacy and telecommunications regulations. Therefore, use the detector only within the legal framework of your country and, if in doubt, seek legal advice.
