This is simply the best cable tensiometer Ive ever used... its easy to operate, it fits in small spaces, and its very accurate. And Matt Vaughn at Sprague Instruments is great to deal with if I ever have a question. Excellent tool!

We had previously owned the original non wireless griper. It was a great tool except the wire would get caught on things. This new warless unit is much better. Easier to use. The reader is smaller and more user friendly. We have now rigged 3 aircraft with it without any problems. We at Bens Motorworks Highly recommend this Tensiometer
