Parabolic microphone for directional eavesdropping - G-PKS PRO/PRO EX

The G-PKS series of directional parabolic microphones is a result of long years of research and development, an absolute pinnacle of technological advancement, performance, reliability, and ease of use. The device's working parameters are near to the limitations posed by the very laws of physics.

This parabolic microphone is a long range air-to-air listening device, offering the highest quality and the very best audio surveillance and interception capabilities. In test conditions, the parabolic microphone reached a 450 meter effective range, while in regular urban areas it is effective in range up to 200 meters. The G-PKS PRO / PRO EX directional parabolic microphone is dedicated for professionals and security services, allowing them to gather irrefutable evidence and obtain tactical advantage while remaining at a distance.

Its very thin, transparent parabolic dish facilitates discreet listening in – it is less visible at long ranges. With appropriate characteristics, geometry, and the material it was made from, the dish has a high reflection coefficient and perfectly focuses reflected sound waves on the parabolic microphone. The G-PKS PRO / PRO EX kit comes with an advanced digital recorder allowing to record intercepted sounds in very high quality. A professional, highly impact-resistant case with protective foam lining ensures complete protection of the kit – also against water and dust, due to compliance with IP67 MIL-STD.

The G-PKS series microphones are available in two variants.
