HARDK Automotive Mechanic Stethoscope Diagnostic Tool (Black II)

Works great, able to tell exactly where noise is coming from

Great little cheap or it's supposed to come apart in pieces.

Seems to work well Weak spring in the headset. Falls off easily. Have to hold it on.

Bought this to help identify a pipe leak in my sprinkler system that was damaged by previous owners.Used the extension rod and followed the track of the pipe sticking the rod into the ground below the sod level. Was able to find leak location to within a few inches along a 50’ section of pipe, in about 10 minutes. To my surprise it was not near where I thought it was, based on sound I heard echoing up a drain pipe to the gutters. Much faster and cheaper than hiring a locator with a GPR machine to map it out and “maybe” find where all the lines crossed, then take guesses on which was the broken intersection.Simple construction and the sound tunes appear easily changed if accidentally damaged.

Works great
