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!

Good item. Works well.

Super sensitive hearing quality. Could detect exactly where noises were coming from and accurately diagnose going forward.

Works great to pinpoint noises and defects. Used on wheel hubs to identify a bad bearing.

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.
