MoFi Electronics Geo Disc Alignment Tool An accurate and affordable cartridge alignment gauge, in use for over 30 years The Mobile Fidelity Sound Lab GEO-DISC stylus alignment protractor makes cartridge setup easy. You will never realize the full potential of your cartridge without properly setting it up, but mounting and aligning a phono cartridge can be a tedious and time-consuming chore. At Upscale Audio, the easiest way, of course, is to simply check the box for FREE setup, alignment, and testing when you buy a turntable and cartridge. (Or, if you buy a turntable, you can send us your cartridge. Note, this free service is not available without a turntable purchase.) If you're doing it yourself, the Geo-Disc makes it easy. Simply place it on your platter as you would a record, and align your cartridge using the printed graph based on the Baerwald alignment curve.
