Automotive Noise Finder Stethoscope Kit with Amplifier and Headphones

Brief Overview

This portable noise finder is a practical diagnostic tool designed for mechanics and technicians who need to isolate mechanical defects in running vehicles. By amplifying engine and drivetrain sounds through a long metal probe sensor, it enables precise identification of bearing wear, gear grinding, valve issues, cylinder problems, and gearbox faults without requiring expensive diagnostic equipment. Pair this with a complementary noise detection device for comprehensive shop coverage.

Key Features

• Long Metal Probe Sensor – Slim, straight design allows direct contact with engine components, bearings, and transmission housings for accurate sound detection
• Integrated Amplifier – Amplifies mechanical noises for clear, audible diagnosis even in noisy shop environments
• Professional Headphones Included – Wired on-ear headphones with adjustable headband for comfortable, extended diagnostic sessions
• Compact & Portable – Lightweight handheld design fits easily into a technician's toolbox for on-the-job diagnostics
• Wide Application Range – Detects failures across bearings, gears, valves, cylinders, and gearbox components
