## Description

Product Description Dual Purpose Set Detects Both Mechanical and Air Induced Sounds. Use the black diaphragm chamber and screw-in metal probe to detect mechanical sounds from 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 and wind noise. For hard to reach locations, remove the funnel and use the hollow tube.

Review: Excellent - especially with a little common sense - The ‘scope works like a champ! Was able to track down an arcing electrical contact under the hood with the engine running. While searching, I used the closed attachment and was able to hear fuel injectors firing, fuel and air running through hoses, mechanical items, etc. In the end, I used the open attachment to track down the arc, then the closed attachment to pinpoint and verify the component. This scope works beautifully! I previously bought and returned an amplified version because all I could hear through it was ambient engine noise. This mechanical one from Lisle works much better for a LOT always money. Others have complained about one of the ear tubes being blocked, but mine were both fine. Now on to the “hatin’” :) I read a lot of complaints that, now that I’ve used this item, are frankly ridiculous. Honestly, you’d have to be dim to not get how this item works. 1) “it hurts your ears” - the ear pieces are drawn together using a strip of spring steel. It was little tight on my head out of the package - 3 seconds of bedding the “spring” outward and what do you know - no more pinching! Personally, I would prefer a smaller ear tip, but I could easily accomplish that with a little sanding. 2) “no instructions” - wow. There is a closed-ended rod with an “amplifier” that is used for sound conduction by touching the item you want to test. There is also an open attachment with a “funnel” on the end that is used to track down vacuum or pressure leaks, or to isolate a sound prior to pinpointing it with the other attachment. The attachments slip into the end of the pickup tube. That’s it. Honestly, if you can figure out how to use this ‘scope, or how to bend/shape the earpieces to be more comfortable, or how to drill out one of the ear tubes if it’s blocked (which definitely is a defect), then you just don’t need this device - any problem you might be able to track down with it would definitely be beyond anything you should be attempting to repair yourself. If these issues seem difficult to deal with then please take your car to a repair shop!! Anyway, this is a great tool that works as advertised and exceeded my expectations. Any reasonable DIY’er should be able to understand and customize this tool for their individual purposes/comfort.

Designed for diagnosing mechanical and air-induced sounds, this dual-purpose kit is highly effective in pinpointing issues in engines, transmissions, bearings, and more. One of its standout features is its versatility. The kit includes a black diaphragm chamber and a screw-in metal probe for detecting mechanical sounds, while the vinyl hose and funnel assembly are perfect for identifying air-induced noises like vacuum or exhaust leaks. Its ergonomic design and lightweight construction make it easy to handle, even during extended use. Overall, the Lisle 52750 Stethoscope Kit is a valuable addition to any automotive toolkit, offering excellent performance at a reasonable price.

### ⭐⭐⭐⭐ Works great, but the part that goes in your ears not so comfortable
*by E***A on March 17, 2024*

After decades of using a length of small heater hose/tubing or an extra long screwdriver pressed against my skull, I decided to buy one of these things with my rewards points. I really needed to pinpoint a sound source in a difficult spot, so I thought this would be a better choice over the hose/screwdriver trick. Also there are other moving parts going on nearby and just add to the noise in the general area. With this thing I can put the 1/8" dia probe in a very specific spot. The attached diaphragm boosts the sound so I can hear even the slightest nuance. Haven't really tried the air noise attachment, but it seems really good just playing around with it. The only serious drawback it has are the ear pieces, they are just uncomfortable for me. I also wish it had a slightly longer tubing section for more reach without it pulling on my ears. Overall a great tool to have when you need it.
