    Make the Wise Choice

    If you’re serious about stringing and maintaining accurate tensions for yourself or your clients, the Wise 2090 Calibrator is a necessity.
    I string on a Wilson Baiardo and the Wise Calibrator works better than anything else I’ve tried, Digital Luggage scales, spring calibrators etc.

    Precise and easy

    Now I have confidence in knowing I have the correct tension, even to the tenth of a pound. Superior to other calibrators I’ve used. Super easy to use and read.
