I always talk about swing weight and I believe it is the most important characteristic of any tennis racquet.  We have three (3) different devices that can measure swing weight and I use every one each time a racquet is strung.

But, did you know the first commercially available dynamic device is more than thirty (30) years old!

Recently I took some pictures of the original device to send to a colleague and I thought a quick little movie would be fun.  Click on the link below to enjoy this magic video!
