    The training and equipment helped me clear a burglary the first time I used it.

    Det. Schaffer

    I gave up on (a competitor VSA) several years ago because it was difficult to master. The VIPRE is much easier to operate and I have much more confidence after completing the examiner course. The training is much better than I received on the old (competitor VSA).

    Det. McCauley

    The VIPRE is the Rolls Royce of VSA equipment. The people at VIPRE really care and prove it every step of the way. I use to operate (a competitor's VSA) and have now found a much better product and a much easier company to deal with in every way.
