    Have any of you guys used these ultrasonic leak detectors for vacuum bagging? What do you think of them ? Are they worth the money?
    Thanks

    I have only made boats to 40 feet with vacuum bags, but we simply pulled a vacuum and then left it to stand to see if there were any leaks, we use stethascopes (plastic tubes stuck in the ears) to listen for leaks, works very well.

    leak detecting stethascopes


    Landlobber,


    The stethascope with a plastic tube sounds like a great idea. Do you add the plastic tube to a stock scope, or purchase them already made? If so, how do you do it?

    I have a doctors stethscope but find it hard to find to find really small leaks.

    I never use the heart end piece, just a piece of tubing, it really screams at you when you hear a leak.

    I have 3 different leak detectors, really should be testing them side by side.

    For me, they are worth their weight in gold.

    Hi Herman
    Its one thing to find the leak around the tacky tape seal but what if the leak is somewhere over the many square feet of the bag? Can your detectors find them easily?
    Please describe just how good they are and what we can expect from them.
    Thanks
    Fred
