The JJN digital PRO-SL8 is a pocket-sized RF detector designed for discovering all types of RF activity, including both digital and analog signals.

The PRO-SL8 is an ultra-compact pocket RF detector with outstanding performance for its size, featuring a 0 to 8 GHz frequency detection range and designed to detect the latest cellular, audio, video, and tracking devices. In addition, with the built-in frequency counter, PRO-SL8 displays detected frequencies up to 6 GHz. Featuring ultra-high sensitivity, it can detect signals from up to 10 meters. 

On the OLED screen, which provides clarity in all lighting conditions, a 20-segment display indicates signal strength along with an audio tone. Such features allow you to precisely pinpoint a signal's source. The 'Burst' Detect feature guarantees all short burst devices, such as those from GPS trackers or GSM-based devices, will be recognized and discovered, even if the transmission is in just a fraction of a second. 

In addition to that, it has 2 working modes: 'Beep' and Silent Vibrate. Once a signal is detected, depending on your choices, the device can produce an audible beep sound to alert you, or it can be set on the silent vibration mode for covert and concealed use, for example in your jacket pocket. 

Supplied with the device is a flexible Multiband Whip Antenna, which further aids in performance improvement and flexibility of the PRO-SL8.

The PRO-SL8 has a very simple interface and work mode. You just switch ON and any detected signal will show on the display. It is a noteworthy device if you are searching for an ultra-compact yet straightforward and easy-to-use RF detector featuring the latest generation technology.

JJN digital PRO-SL8 Feature Focus:

0-8GHz Detection

PRO-SL8 features a 0 to 8 GHz frequency range, an extraordinary performance for a pocket-sized detector. It is designed to detect and locate transmissions from all RF signals including the latest cellular, tracking, covert listening, and video devices. 

Built-in Frequency Counter

With the built-in frequency counter, the PRO-SL8 is able to display frequencies of detected signals up to 6 GHz. This feature allows you to accurately determine what signal types are present while scans are being performed and distinguish analog from digital.

Ultra sensitivity

The PRO-SL8 can detect signals from up to 10 meters, indicating signal strength on a 20-segment display in addition to an audio tone, which enables you to pinpoint the exact signal source. To improve sensitivity and performance, the device also comes with a flexible Multiband Whip Antenna.

'Burst' signal detection

The 'Burst' Detect feature will make certain short burst devices, such as GPS trackers and GSM-based devices that transmit data in short regular bursts, don't get unnoticed as they are usually missed using lower quality bug detectors. The PRO-SL8 catches the signal even if transmitted in a blink of an eye. 

Audio demodulation

With the Audio demodulation feature, you can listen to the detected signals through the supplied earphones which allows you to better differentiate regular bugs with microphones from harmless detected signals such as broadcast radio. 

2 working modes

There are 2 working modes you can choose from. The 'Beep' Mode produces a tone when a signal is detected, but if you wish it to remain silent and unnoticed, you can set the PRO-SL8 to silent vibrate mode. This mode will pulse and vibrate silently when a signal is detected, allowing you to keep the device concealed, in a jacket pocket for example. 

Quality build

The device is set in machined aircraft-grade aluminium enclosure for maximum durability. It uses an integral Lithium-Polymer battery back, which provides you with up to 6 hours of uninterrupted operation time. The whole system comes in a protective plastic carry case for ensuring safeguarding and portability.
