• Dual purpose set
• Use the black diaphragm chamber and screw-in metal probe to detect mechanical soundsfrom bearings, engines, transmissions, etc
• For air induced sounds, attach the vinyl hose to the hollow tube and funnel assembly
• The funnel amplifier will detect noises from vacuum leaks, exhaust leaks, air leaks andwind noise
• For hard to reach locations, remove the funnel and use the hollow tube
• Have you ever needed to locate or isolate a sound or leak in order to fix it? This detects both mechanical and air induced sounds, it's a dual purpose set. The funnel amplifier will detect noises from vacuum leaks, exhaust leaks, air leaks and wind noise. It's great to have and easy to use!
