I think your $60 bucks could have been better spent. Here's why: When it comes to bobbin tension, one must first consider the machine. The embroidery machine will be either a "conventional" type machine or it will be an "Amaya" machine. Conventional meaning every embroidery machine other than the Melco Amaya. Conventional machines will have to have the upper thread tension in mind when setting the bobbin tension where as the Amaya machine utilizes it's patented "Auto Acti-Feed" system. But for the most part, setting the tension will be the same. How much tension you choose to set will be up to you depending on your results. Consider this... When it comes to bobbin tension, there is an acceptable RANGE that one could use. Get your bobbin tension anywhere in that RANGE and all will be good. If you go outside that range, too loose tension will result in bobbin showing up on top of the garment and possible thread breaks and on the other end of the range, too tight tension will result in possible top thread looping, fabric puckering, top thread not picking up of the bobbin thread when you start sewing. Therefore, there is no specific number that you are trying to aquire with your tension guage. If you find one, let us know. Consider this. Keeping your bobbin case clean is essential because a dirty bobbin case will cause you to have either too much tension or too loose of tension. And it can go back and forth all the while you're sewing. What's great about the Amaya machine is that as factors change, such as a dirty bobbin case, the "Auto Acti-Feed" system will auto compensate by adjusting the upper thread feed (on the fly)to attempt to maintain balanced thread tensions. That fact alone makes you want to say WOW! However, you should still clean and check your bobbin case on a regular basis should it need it. I hope this helps.
