Monocular Telescope High - Definition telephoto Mini Telescope Professional telephoto Zoom Lens.Best for Hunting, Sightseeing, Golf, Surveillance, Shooting.

I bought these. All under $20. - Celestron upClose g2 10x25 (71213) - HDE 15X Zoom Compact Monocular 21mm - Roxant High Definition Ultra-Light mini - Imaisen no name. Bought because it had "Amazons Choice" on the page. Only 1 review.To get right to the point. The Celestron UpClose g2 was the only "usable" monocular in the bunch. Even that has a very small aperture (like looking through a straw.) But, at least it was relatively easy to get a sight and pretty clear once you had it. I am keeping it.This Roxant was the absolute worst of the bunch. Cloudy, could never get a good focus...and in a group of very cheap monoculars, this thing felt the cheapest. But, it was actually the most expensive. The rest were cheaper.The Imaisen (Amazons choice) was close to the Roxant in crappiness. Cloudy, lousy focus...just miserable. lol.The HDE 15X Zoom Compact Monocular 21mm, I am on the fence. It actually has a pretty darn good zoom feature. You really can zoom much closer than any of the other monoculars. It was surprising actually...if you could find what your looking at. It was almost impossible to focus in on any object. If the others were like looking through a straw...this one was like looking through a pinhole. I spent considerable time trying to line up a sight picture to where there is actually an image in the scope. I believe this is called Eye Relief...and it is absolutely horrible. However, once you did find an object in the distance and zoomed in on it, it was a lot larger than any of the others. It was impressive...for the entire second I could hold the image. This should be called Small & Shaky. Still, I'm thinking of keeping it cuz the zoom is kinda cool.So, I'm keeping the Celestron and I'll pop it in our camper or truck, just to have something. But, I am definetely going to get something better. After looking through these things for an hour or so, then picking up my Nikon 7x50 Binoculars...I almost cried.Hope this helps.- SF

I use it to quickly read locations and/or labels of pallets in high places in a warehouse. It really saves time as I don't have to pull the pallet down (and put it back up) just to confirm what I need to know. Takes some getting used to aiming what I want to see, but the view is clear, though shaky if you don't have steady hands.

This thing is a hunk of junk! But what can you expect for $10? The eye relief and focus are so bad this thing is pretty much useless!!

ok for the price not supper clear lens but ok for the price

This is great for Star gasing !

Provides no magnification what so ever.Threw it in the garbage. Not worth the headache of Amazon return.
