So what is it?
These are my analog magnifying tools/ I mainly use that big one with the 2nd smaller lens inside the big one. I'd like it at the top of the circle but no way to loosen the glass in the frame to rotate it. The big lens is about 4 or 5X and the little one is maybe 7x. Good enough to find thrips and mites and cover a lot of ground fast when checking out a bunch of plants. I always look for leaf damage then start hunting around that.
The little 10X loupe is good enough to see trichs but not real close. Easy enough to tell if clear or cloudy and spot ambers if there. You can get all sorts on AMZ for cheap and drug stores carry the big ones in their stationary supply areas. $15 here for one like mine.
I bought that 30x Radio Shack one 20 years ago at the store in town for $12.95 and it works great for a close enough look at trichs still on the plant and the pop-up 8x magnifying glass is handy when I can't find the damn loupe.
The USB scope is hard to focus but for something like determining if you have a mould or fungus growing on your plants or your drying buds it's just the ticket. Or for examining larvae etc to get an identification.
