You can always know when you need to restring your racquet thanks to the Gamma® String Tension Tester. The tester measures relative tension loss of strings over time, giving you quick readings with more accuracy.

This is a tension tester - but only for relative use. YOu don't get a tension measurement in pounds, you get a number in units. The number then you record and compare to other racquets or compare to what you recorded when the racquet was first strung and see if it is losing tension. It's still handy for that, but don't count on it to measure exact tension in lbs.
Bottom Line Yes, I would recommend this to a friend
