Jizmo 8x25 High Definition Monocular Telescope, Close Focus 1 ft, Fully Multi Coated Optical Lens BAK4 Prism, Mens Gift Wide View Monocular for Bird Watching Travel Sports Events

This is a high-quality instrument with generous eye relief, a sharp image, and a very comfortable focusing range from 30 cm to infinity. Unfortunately, I noticed an artifact in the field of view that couldn’t be removed even after cleaning the lenses.I returned the product and took the opportunity to inspect some of its competitors:Opticron 8x25 Trailfinder T4 Monocular The eye relief is inferior—you can see the entire inner circle of the eyecup lens—and the focus adjustment feels awkward and imprecise.The same issues apply to the Leica Monovid 8x20, which also has a narrower field of view, a heavier build, and a stiff, inconvenient focusing mechanism. While its image quality is comparable to the Jismo, it comes with an exceptionally high price tag.In the end, I decided to reorder the same product, hoping that the previous issue was just a one-off flaw in workmanship.

Love this monocular. Its so much easier than using binoculars, because you have better control over hands shaking, plus it’s lighter. Its got a clear picture too, and you can’t beat the price.

This is a nifty little instrument.It will open up a huge world of up-close observing.I own alot of optics,and this is the only instrument I have that will focus from 14" away,to infinity.Excellent image sharpness.The power is a full 8x as advertised.About the only con would be the focusing.It could be a little finer,but the focus ring turns nice and smooth,so its ok overall.I would suggest using the ring to achieve a rough focus,then move your body toward or away from the object to get the fine focus.If you are into nature,and observing insect life,this instrument will quickly become your best friend.Excellent for the money.I would say the best use for this scope would be to set it up on a tripod,aimed at your favorite ant hill,and observe with joy and clarity all the ants doing their stuff.It would make an excellent close up nature insect scope.

Great little scope! First, let me tell you where I’m coming from with this review. I’m not new to optics, and have many high end devices such as Canon 10x30 IS image stabilized binoculars and others. I’m also into photography and have a Canon DSLR and L series lenses. I’m not as “wowed” by an optical device as someone new to buying optics might be.That said, I REALLY like this little scope. It’s the perfect size to pack in a jacket pocket. The image is bright and clear, and from edge to edge. If there is any chromatic aberration, (Rainbow fringes around hard edged objects) I’m not noticing it. A lot of cheaper binoculars and monoculars seem to suffer from center sharpness and around the edges blurriness, but this scope is NOT one of them. It’s also very lightweight, so I can use it for a long time without any muscle fatigue.The focus ring is at the front, so it’s a two-handed device. There is a slight touch of slop, you have to go back a little (1/16 turn or so) to take up the slack and turn the other way to get perfect focus. Most scopes other than maybe a $1,500 Zeiss will have this, so it’s not a problem. The focus ring is firm but easy to twist. The ring is also metal with a nice knurling and is easy to grip with fingertips. Once you’re focused for more than a few hundreds yards out, there’s no need to reset it. An unusual thing for this scope is the close focus; down to barely more than a foot away. I would think observing spiders and insects with great detail would be a fun summer thing to do.The eyepiece guard unscrews to extend out for your eye, or in to use with glasses. With it all the way out, I’d say you get about 97% of the view. The eye relief of 16mm is generous; short eye relief causes “tunnel vision” or a too-narrow field of vision. Finding what you’re looking for is fast and easy, no “blacking out” as your eye stays in alignment. And that’s not insignificant, a short eye relief can ruin an otherwise good scope.This is a very good scope for daytime use, but is bright enough to be fairly okay in the dark. The laws of physics apply here, 8x25 will never be a good night use scope because the objective lens isn’t large enough. If you need low light, go for a 8x42 or 8x50. Of course, that will make for a much larger monocular. 25mm is about an inch, 32mm is 1.25 inch, 42 is about 1.5 inch, and a 50mm is almost 2 inches.8x is perfect for a handheld scope as any higher magnification just gets impossible to hold still enough to see any details. There’s a reason marine binoculars are generally 7x50, the U.S. military decided decades ago that 7x is the maximum magnification practical for handheld optics without image stabilization. (Recent technology) If you’re shopping for a monocular, beware of 10x or higher, especially zoom scopes (such as 10x - 30x) because they’re just useless without a tripod. The only way to see details is to have image stabilization such as Canon, Fujifilm, and others (binoculars) that cost hundreds of dollars. When jiggle is bad enough, you cannot read a sign or license plate, or even positively ID a bird variety.The form factor for this scope helps a lot with the jiggle factor because it’s short. The longer a scope, such as tube type designs, even the slightest lateral movement causes bad jiggle and makes details too hard to see. I can wrap my whole hand around this scope, and brace the eyepiece against my nose, and it makes for a very steady view. And, as a bonus, there is a standard tripod threaded hole in the bottom. That means a tripod if you’re watching birds and are seated at an observation station. Or a glass-edge camera mount in a vehicle, or even a monopod while hiking. This scope is more for hiking for me, as I’ll be using image stabilized Canon binoculars when driving the Jeep or watching wildlife while not moving around. (i.e. camp chair in a blind) A monocular is easier to use from a vehicle window than binoculars to scout wildlife.The scope comes with a cloth draw bag, a hand lanyard, and a cleaning cloth. My scope came with a somewhat damaged escutcheon, (Legend-surround on the objective lens) but isn’t worth removing a rating star. I did not attempt taking photos through the scope as they would not do justice to the image you actually see.
