Minimum focus?

[BSJ]

Do prism sights have a minimum focus range?

Would 2-3 yards be too close at 4x?

 The better ones eg. https://immersive-scopes.co.uk/product/ will focus down to 3 yards clearly

Bummer. Guess not really better than my bug buster.

I was hoping it would be red dot like...

 I went and checked my bargain one, it does well to 7 yards, then the target becomes progressively fuzzy, there is no parallax error, just fuzzy targets.

 I got to thinking the 1x on my Jet is good no matter what the distance, better up close.

Thanks for that.

Got some rats under my bird feeders. I can just see their beady eyes peaking from under flagstones. 6 to 8 feet from the window. Need some magnification and a sharp reticle...

Sounds like open sights are what you need!?
