In addition to 2-point and arc protractors for turntable setup, you can now generate custom sightline protractors on this site.
Just like 2-point protractors, sightline protractors are universal (generic) and can be used with any turntable. They only use one grid, but this is enough to align the cartridge to any geometry. The sightline, pointed towards the tonearm, ensure that the protractor is placed correctly.
