  • High Quality: The engine stethoscope is made of high quality stainless steel and heavy-duty vinyl tubing, sturdy, reliable, abrasion-resistant, not easy to rupture
  • How To Use: mechanical stethoscope probe can pinpoint the source of the sound, earplugs isolate the outside noise, and the audio shock amplifier ball amplifies the sound; simply follow the loudest sound in the engine and make contact between the probe and the surface to confirm it; if you can't detect the problem right away, you can check other places

    • Pinpoint the Noise.
Color: 1Pc
Excellent tool for pinpointing noises from vehicles. Engines, pumps, solenoids and relays. This conducts the sound and at the same time filters out the rest of noise from the engine. I use to use the screw driver and broom handle trick but that was a little hit or miss and sometime difficult to get into tight places. This is a must have for the DIY shade tree folks. Pros: Good sound conduction, length of probe is decent, two piece probe allows for fitting in most tool boxes. Cons: The two part probe/conductor often come loose during use. Needs to be tightened periodically during use. Over all it has saved me from tearing into things that weren't an issue but presented as potential issues. ... show more

The plastic that contacts the ears is kind of hard. Aside from that, it's a great instrument for the price.

    • Decent Mechanic’s Stethoscope – Gets the Job Done
Color: 1Pc
This stethoscope works fairly well. I was able to pinpoint a ticking noise in the engine, which made it worth the purchase. The tubing is a two-piece design that screws together, and it feels a little flimsy because of that. However, it does what it's meant to do and is affordable enough to keep in the toolbox for quick diagnostics. ... show more

    • This is a MUST-HAVE for mechanics.
Color: 1Pc
My Harley motor was making noise but it was impossible to precisely isolate the source. I suspected bad lifters which could only be properly diagnosed by removing the pushrods and then removing the lifters. Which also meant first removing all of the exhaust! My solution was to use a stethoscope which I'd never used. In looking at options and cost this unit seemed to offer the most options and flexibility for the price. I was absolutely astonished at how well this performed and the way it worked to pinpoint my noise almost immediately. I used the long metal vibration probe putting it in direct contact with the engine case in numerous points. I could hear clearly and learned that in fact there were no real issues, and certainly no problems with the lifters, rocker arms, cam chain, compensator or bearings. In fact I learned the noise came from the primary chain which simply needed to be properly tensioned. Saved me an unnecessary tear down in just a few short minutes. I came away with unexpected peace of mind and new indispensable tool! ... show more

    • Sub Par Construction. (Cheap)
Color: 1Pc
Works good but quality is lacking. It really is cheap construction, but since it still works I will continue to use it.

    • A Must Have for Diagnosing Noises!
Color: 1Pc
This product is basically a must-have for any shade tree mechanic diagnosing noises under the hood. I had a horrible whining sound on my truck, and tried to use the old screwdriver-up-to-the-ear trick to diagnose the source of noise. That method did not give me quite nearly the definitive proof that this stethoscope provided. Once I used this product, I was easily able to trace the source of the noise back to my trucks A/C Compressor. The extra long probe made it very easy to get down low in the engine bay and make solid contact with the compressor. Found the noise! The earpieces fit nicely in my ears, providing good comfort and function during use, and the whole tool feels to be of high build quality. It should last indefinitely with proper storage during non use. As a bonus, you get to feel like a "car doctor", pulling out your handy dandy auto stethoscope. Worth it for that novelty alone! ... show more
