JMI hand controller vs. FCUSB

Last night, I found the JMI hand controller is a bit too coarse in fine focusing, for visual observation, it's okay, but for imaging, I found it a bit easy to overshoot the exact focus.

Previously, when I said it's too slow, but after some usages, I found it's actually too fast, even at the slowest setting on a very old 9V battery.

On the other than the FCUSB from Shoestring Astronomy is finer, got to use it more often whenever possible!
