Thermal scope question - Image calibration feature

I have an AGM Clarion 640. There is a feature where the scope calibrates itself. It can be set to Auto, Semi, or manual. How do you like to run yours?

The negative is that on auto, it could decide to calibrate itself right when you take the shot. On the positive side, it is one less thing to be doing and the overall image will probably be better.

I am leaning towards semi auto mode or manual mode. However, I am not really sure of the difference between semi and manual. Both require a simple press of the mode button. The manual requires the lens cap be closed. Does anyone know the difference?
 
If you aren't moving quickly, image shouldn't auto calibrate frequently. So if aiming at a critter you shouldn't have an issue. I run mine thermal on auto. I mainly hunt in the winter, cold temps/frozen ground. Environmental factors will also contribute to needing image calibration.
 
Auto here also. I tried semi a few times but would forget and in high humidity it can deteriorate quickly and often. In auto, you can always manually NUC at any time if you so desire anyhow.
 
Jmeddy, that is a great point. If I see something far in the distance, I can manually NUC and preemptively prevent a NUC at the wrong time. Great idea.
 
i have the bering optics super yoter. its on auto, only nuc one time when i was trying to kill a coyote. i dont think its an issue.
 
Auto for me.

I remember the Super Yoter would give you a few second warning before in auto-NUKed. One thing that I've noticed on my iRay Rico 2 is how fast it NUCs, much faster than any thermal I've personally used. There's a guy on another forum that has posted vids from an ATN Thor 5. It's Nuc process I'd guess is twice as long as the Berings I've used. I could not deal with that.
