Tourna String Meter String Tension Tester Black ,One Size

I used to string my own racquets using a counter weight which is in my opinion is as accurate as you're going to get, about 15 years ago and purchased a stringmeter to help verify my tension after stringing was complete. The mechanics of the metal coil in the string meter is pretty consistent. I just bought another one recently, the same exact product and compared the two and they are very close to the same accuracy after 15 years. The digital stringing machines need to be regularly calibrated and if the stringer is not disciplined enough to keep it calibrated, it's anybody's guess what tension you end up with. lThat's the reason I decided to string my own raquets. Good stringers are hard to find. If you are still in doubt, try a different stringer.

My racquet was supposedly strung at 40 pounds. The String Meter came out at 40 pounds for the long strings, but only 30 pounds for the cross strings. I took a few measurements from various tennis friends racquets. More often than not, the measurements were rather unsettling and seemed to have little correlation with the supposed racquet string tension they had ordered from the stringers.I think this gadget works really well in terms of measuring the string tension of your racquet over time. You can tell how much tension your strings are loosing over time. But, in terms of checking the accuracy of your friends racquets I am not too sure how well it works.What I get from this is that racquet stringing is a very imprecise art. Let's say you order string tension of 50 pounds with the exact same racquet and same strings from several different stringers. I have no doubt there will be marked differences between all of them. I suspect this difference could be associated with a very wide range. Between the lowest and highest you well could have a difference of 20 pounds (you order 50 and you get a low and high of 40 vs 60). The second issue is how do you measure this accurately. That's a tough one. I am not sure how precise the Stringmeter is.Another weird finding is that I observed that the cross strings often come out at far lower tension than the long string. This is counterintuitive. From a physics standpoint you would think the opposite be true. A shorter string is much less flexible, and returns greater resistance to any torquing than a longer string. However, in essence the cross strings and the long strings make for two completely separate string jobs. Is there something in the standard stringer technique that make it so (that cross strings are associated with lower tension)?

For how much this thing costs, I expect a whole lot more. It looks and feels quite cheap, like it could have been made for a couple of bucks at most. That I could forgive if it worked correctly. However, on my freshly strung racket, at 55lbs, my sample reads - *30*. I verified it with a few other rackets and it is essentially reading 20 or more lbs off of the true number. I get that it just has to be consistent for it to be useful, but it does need to be close to the right number too. I've returned it as defective and I'm expecting a replacement. We'll see if it is any better. I'd just return it if I didn't instinctively toss the packaging already.

I returned it since I do ‘t think that it is accurate. I had difference reading every time and it is off about 10lbs to what my stringer is reading

I think a lot of folks don't "get" this tool. Absolute accuracy is not an issue. Think about it. You will be using this device AFTER you've had your racket restrung or to check the approximate tension of strings on a racket that's unfamiliar or new to you. It does not matter if it's "off" by 1, 2 or even 3 pounds. Properly used, it will tell you how rapidly your string tension decreases AFTER a restring. That is important information. It will also give you an approximate idea of string tension on a demo or used racket you're considering playing or buying. It's a great tool if you're a smart enough player to understand its actual purpose.

El producto se siente de mala calidad, no está bien terminado y tiene defectos de fabricación e impresión. Puede que cumpla su objetivo pero, en general, esperaba más considerando su precio.

Before purchasing this item, I read many of the reviews posted on Amazon regarding how inconsistent this device is, and how readings are different at different locations on the string-bed. I have found exactly the opposite. Firstly, the instructions clearly say that the device should be used at the center of the racquet, not at random locations. Secondly, I string my own racquets and use this device to determine the accuracy of my job. I find that this device measures string tension with a high degree of accuracy every single time, matching the tension I had strung the racquet at. The key is to ensure that you set the string gauge on the device to the string gauge on the racquet.Over time, the device also indicates when tension loss is encountered, and when to change strings based on obvious performance changes to your game. My only minor complaint would be that within 1 hour of using this device, the spring popped out of it, but was easily re-inserted thereafter and it retained its accuracy after the fix. Be careful when using it to prevent this from happening.In conclusion, not only does this device indicate when I string racquets accurately, but also when to change strings and which strings tend to last longer than others with regards to tension maintenance. Highly recommended for any serious player.
