Wise Electronic Tension Calibrator

I purchased this calibrator based on the good reviews I had read about the product and I was certainly not disappointed. It is extremely accurate and the digital display makes calibrating your stringing machine to the perfect tension simple. I've used other tension calibrators in the past and none even come close to this product. The Wise Electronic Tension Calibrator may be more expensive than the other calibrators on the market, however, it is well worth the money.
