I saw a Cambron B4 Zooming Monocular for sale for around $30. Looks like 60mm aperture, pretty housing, and decent AFOV at 20x. Only "multicoated". It is an older model.

 

I'm just wondering if it would be enjoyable and worth the money or if I should pass on it.

 

The link to a picture is longer than just googling the name. It appears in good condition, but no case.

It's probably worth a gamble. The pictures of it look like an old 7x50 monocular that I made when I was a kid. Only this one zooms. I used that thing for many years and it even went back packing with me. Star gazing in the Sierras was incredible!  waytogo.gif

From the specs it sounds like a small spotting scope. You would have to mount it. I can’t see if that is easy. Or lay against something. Also it probably will suck at the magnification ends. Eye relief tends to be poor in old zooms. Otherwise it looks ok. I don’t think I would use it and for sure not at night.

True, eye relief can be bad at high power, though that eyepiece sure looks fancy, like maybe it is figured out. 60mm aperture.

I wondered how it is mounted to a tripod. The ad lists one. No picture of a screw hole though. I could ask.

Seems definitely for daytime use. Though portable, a glove box might vibrate it.

 

 

I'm also wondering if I buy it and don't like it, how hard would it be to sell. Some places have sold them for more, others a bit less.
