Fantastic Scope - Wish I knew what "Awaiting Auto-Correction" does!

Love the feature set and the functionality but one undocumented function is bugging me. If you Long Press the AUTO button, text pops up saying "Awaiting Auto-Correction" and then nothing happens. All the buttons are locked and you must press the Reset hole to fix. Very odd.

Keshaun King

Excellent but it took a long time

Leland Nolan

all ok good working

Juvenal Boyle

Looks great. Sometimes, it can't do automatic settings, and it freezes for a long time until discharge or reset. In general, for education purposes and sound measures, it is great. Excellent packaging.

Leslie Hegmann

Arrived in good condition. Just what I needed for the moment.
