Does anyone know if someone makes a dual night vision and thermal scope all in one? I thought I saw one at a gun show a few years ago. You could flip a switch to go from one to the other depending on circumstances.

What are the differences?

Is one better than the other?

Which one is the best bang for the buck?

Would be using it for both night hunting (legal for varmit, wild hogs) and SHTF.

Thanks.
