Sensitivity for Accurate Diagnostics This engine stethoscope is designed to amplify and transmit even the most subtle sounds from engine components. Its sensitivity allows you to quickly and accurately pinpoint the source of abnormal noises without the need to disassemble the engine. Ideal for identifying issues such as bearing wear, valve irregularities, and other mechanical faults. Durable and Reliable Construction Crafted from stainless steel and ABS, this stethoscope delivers longlasting performance. The stainless steel construction offers corrosion resistance, ensuring reliable operation in demanding workshop environments. The ABS components provide strong durability to withstand everyday use and handling. Smart and Practical Design Equipped with a 21.7inch wire and a 3.5inch listening tube, the stethoscope offers flexibility for various inspection tasks. The included 8.7inch extension probe makes it easy to access confined or hardtoreach areas within the engine compartment, enabling thorough diagnostics with minimal effort. Simple and Efficient Operation Using this diagnostic tool is straightforward and efficient. Attach the desired metal probe to the stethoscope body and secure it. Place the probe against the engine surface and listen for sound variations through the earpiece to determine the source and nature of the issue.
