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 Skerton Pro
The Pro revision fixed the original Skerton's wobble, which was the main source of its inconsistency. Filter and French press are comfortable; espresso is technically reachable and practically frustrating.
