Principle of operation
It is designed to detect and locate signals from the very latest covert listening, tracking, cellular, and video devices. With a completely new hardware design the PRO-SL8 has unrivalled sensitivity for its size and can display detected frequencies up to 6 GHz.
The PRO-SL8 also features audio demodulation to allow the user to listen to any detected signals using the supplied earphones. For ultimate durability, like all JJN Digital products, the PRO-SL8 is housed in a machined aircraft grade aluminium enclosure.
