The best phono cartridge alignment tool

Best Tractor/ Arc Protractor----i own one for each arm. easy to see with my 70 year old eyes, unambiguous. a no brainer.

i own a number of other alignment tools including the Feickert but never use them.

I use a Feickert along with one of these to help with azimuth:

I've owned and used many of the protractors used for setting up arms.  Unfortunately, most of the better ones do cost more than $300.  If you can easily find the center of the pivot of the arm, the easiest to use is the SmarTractor.  It is a one point alignment and the device never has to be rotated to a different position.  It is very easy to see when the alignment is correct.  The Wally Tools device requires more work, but, it gives one more confirmation that the alignment is correct and one does not have to find the center of the arm pivot.  The Feikert is reasonably easy to use, sort of like the SmarTractor, but, I like the very precise markings on the SmarTractor more.

the other big trick with alignment tools is turntable height and sight positioning. if you can get your body to be at a height and angle where you are comfortable enough to be in one position for extended periods, then the odds of a better set-up are increased. 

many times i see turntables on low racks or crowded into corners and i wonder just how meticulously those tt’s can be set up?

tools are only as good as our ability to use them. setting up an arm or cartridge should be a pleasure and satisfying. or our results will be diminished.
