The fine adjust on top can be tricky to set with a half or tenth indicator. I do it all the time with no problem but it required some practise.
My choice was the medium size because it had a stronger magnet than the small one for vertical surfaces, and the extra reach into tight spots has been handy on occasion. I have two DG61003 and might get a third one eventually to mount a third indicator.
