    AM 250

    Orinally comming from the automotive industry where I spent the majority of my adult life, I have used many diagnostic instruments inorder to complete the tasks at hand. As an automotive electrician, the AM 250 was and still is a life saver. It comes with a vast amount of connecting cables that can gap the spread from one industry to another. This is a quality made professional product that can take the pain out of making the right diagnosis from the get go, and can be used for electrical diagnosis on a 2000 AMP electrical service panel within my shop a few minutes later. This was not my first AMP Probe product and surely not my last..

    ✔ Yes, I recommend this product.
