Smart solutions for soldier protection

METRAVIB PEARL is a miniaturized acoustic gunshot detection system initially designed for infantry and dismounted soldier who is in direct contact with the enemy. PEARL provides the capability of finding in a few seconds and in a very intuitive way the origin of the shots that are threatening them.
The PEARL system can be installed, using a Picatinny rail, on an assault rifle, a sniper rifle, a machine gun or multifunction goggles/sights. An intuitive interface composed of directional LED arrows shows the azimuth and elevation of the threat. Compact and wireless, PEARL is easy and fast to get started with.

The RS232 or RS422 interface of PEARL allows coupling, after a short adaptation study, with other systems. Range and calibre information is then available. The following couplings are already available:

  • day/night weapon sights
  • multifunction thermal goggles
  • handheld ballistic calculator
  • smartphone battlefield management applications
  • robotics unmanned vehicles
