ELECTRONIC STETHOSCOPE - HIGH SENSITIVITY ACOUSTIC AND ELECTRICAL FIELD MONITORING
The Electronic Stethoscope is designed specifically for the EOD field, where it is necessary to detect very weak sound waves from mechanical clockworks fuses, electro mechanical and electronic device objects suspected to contain explosives, also where weak sound waves have to be detected. Engineered with a highly sturdy design fitted with splash water protection, the system features user-friendly electronic controls and a soundproof comfortable headset. The operating principle is based on the highly precise detection and amplification of sound waves using both contact and non-contact search heads.
- Structural Acoustic Tracking: Capable of detecting faint timer sounds through dense solid materials such as brick walls, glass, wood, and packing materials.
- Noisy Environment Immunity: Search head is completely immune to surrounding loud noise, ensuring reliable detection in high-risk environments.
- Advanced Tactical Connectivity: Equipped with dedicated headphone connectivity for easy, direct use with Bomb Suit Helmet and visor assembly.
