When you look through the eyepiece of that device, you are essentially looking at a small LCD screen rather than a projected image. As a result, if you would normally read using reading glasses, you would most likely still need reading glasses to make out details in the image, or at least to view the settings and menus.
No, it does not.

The Predator 336 is no longer in production. Optics Planet offers this model in 60 Hz:

For these original Armasight units, the recommended maximum caliber is .308.
I think that I found the answer to my own question. One of the reviews on this site from 2016 says: "the manual says i can use the objective lens to focus it in but my front lens will not turn so i cant adjust it i would love some input on this."
This seems to confirm that the front lens does not have a focus knob that turns.
You can record video, but the unit would require an additional DVR accessory to do so. We unfortunately do not offer the DVR accessory at the moment.
The displays resolution is 640x480 while the thermal sensor is 336x256.
The refresh rate is the number of images viewed per second. Like a movie, video is rapid progression of one still image after another. The human eye normally can’t see the difference between 30/sec and higher video rates, however, if you are following a fast moving object, or panning rapidly, you might see a little difference as a slight flicker. I bought the 30hz version because the price difference in the Opmod version was hundreds of dollars less. I really don’t see any significant difference. Bottom line, if you want to never see flicker, buy 60. If you want to pay less, buy 30. You won’t regret either choice as both are great thermal scopes.
60hz is provides a smoother image, which can be crucial when tracking moving targets. The tradeoff is that 60hz is typically more expensive than the 30hz.
