The same number means different things
Both grinders use a clicks, which makes it tempting to copy a number straight across. Setting 50 clicks sits at grind index 2.7 on the JX-Pro but 47 on the M47 Classic — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.

Dialing in the JX-Pro
External adjustment makes this the easiest hand grinder to actually dial, because you can count clicks without disassembling anything. Its filter range is generous, which is a mixed blessing — small click changes do less than you expect at the coarse end and more than you expect near espresso. Move in larger jumps for French press, single clicks for anything under filter.
Dialing in the M47 Classic
A heavy, precision-built hand grinder with stepless adjustment and genuine espresso capability. The lack of detents means repeatability depends on your own reference marks — the settings here are targets rather than clicks.
