Monocular Telescope, 10x42 Monoculars for Adults, Usogood Compact Portable Waterproof Monocular with Hand Strap, Lightweight Handheld Pocket Telescope for Bird Watching

The media could not be loaded. Pros:- Well made- Good optics for the price- Price- Size- Can be connected to a smartphone using a 3rd party smartphone holder. I recommend the SVBONY smartphone holder. Take note it's tricky to mount if you have a multi-camera smartphone. I built an additional part to make sure i don't get too much glare in the lenses which affects the quality of image captured by the smartphone.- I can see sun spots of the sun (Warning: I have to use a solar filter in front of the telescope to protect my eye. I built the filter adapter myself. Please see pictures)- It's great even if it is dark.Cons- The tripod mounting nut can detach if you tighten the tripod screw too much. Don't apply too much twisting torque as it can pop out of the hole.- The nylon accessory that you attach at the right side of the scope to allow you to securely hold the telescope with one hand is a bit difficult to insert in the holes provided. It is also difficult to lock it in place as the nylon strap just slides off easily. It's not a deal breaker but I wish it was designed better and the nylon strap should be a bit longer in length to allow a better locking grip between the nylon and the locking buckle.Observation:I am not sure if this is a real 10x . I have an 8x binoculars and when I check the image magnifications, they are almost the same. I don't mind because it is still very usable. Other scopes in the market are not properly rated. They say it's 80x50 but in reality the 80x is more like 8x and they fail to mention that 80x is if you use the 10x digital zoom function of a smartphone which to me will just give you very crappy images. Don't fall for it. 8x to 12x is the most usable for nature tripping or hunting. Anything above 12x will require you to use a stable tripod. 10X42 for me is the sweet spot. Enough magnification, not too heavy and bulky compared to 8x50's.Update 4/19: I compared it to my binoculars with 8x magnification and I can confirm that the images in this 10x monocular are slightly larger vs the 8x bino.I used it with a Samsung S22 and Samsung A54 during the solar eclipse to take videos of the event. I fabricated additional components to be able to mount a solar film that also looked good, and an additional part that prevents glare on the lens where the smartphone is mounted. I had to fabricate it because the smartphone adapter I bough did not come with one, and it will still work without the anti-glare thingy. I used the smartphone adapter from SVBONY and it securely mounted my smartphone behind the telescope. Do take note it takes some patience to align the lens to the scope. If you combine it with a smartphone, your magnification power increases depending on the capability of the smartphone. Some smartphones have digital magnifications, some have optical and digital magnifications. My smartphone is equipped with 3x magnification which gave me a theoretical optical magnification of 30x. If you use your naked eye, 10x is more than enough for a hand held. Coupling it with the smartphone's camera will require you mount your scope on a tripod. Without the tripod, you will get bad images or shaky videos.Note: if you plan to shoot photos using a smartphone with it, It's much trickier to use a smartphone with multi-camera lenses but after some testings and tinkering, I was able to find the right settings that allowed me to zoom clearly with enough lighting and no vignetting. It takes patience and practice.I have not tested the water proof feature because i have no intention of using it on a rainy or watery environment. If the opportunity arises or if I get into a wet situation then I'll probably use it but I will not intentionally submerge it.The 10x42 is just about the right size for me. It's light, but not plasticky light. The size allows me to put it inside my winter jacket pocket.It's a perfect all around tool. It's also a perfect tool for inspecting some installations that's more than 10 feet high or that are too far to climb.It comes with a diopter knob but I am not sure if you really need to adjust it. There is already a focusing knob available. I normally do not touch the diopter adjustment. I just leave it and I adjust the focus via the focusing knob which is very accessible and easy to use.It's durable. It already fell once from about 3 feet of height and it survived. I already used it for long hours under the sun.The video I attached is digitally cropped in post processing and was originally magnified equal to 20x (optical). With a solar film attachment that I fabricated, I was also able to use it also without the smartphone and I can clearly see the sun spots! and the image was a lot bigger than that what was captured in a smartphone without using digital magnification.The small picture of the sun in t he sample pictures is what you'll get when shooting pictures from a smartphone without the use of the zoom function of the smartphone. The picture of the helicopter shows black areas. If you don't want the black areas, you simply use the zoom function and you instantly get full screen. take note that the quality of the image will depend on your smartphone's zoom feature.Overall, I love the scope and it's definitely a keeper.

This is great, I have had it for about a year now and use it all the time.

It works and quite handsome looking

Not much in the way of bells and whistles, but crystal clear and easy to use. Well priced.

😍😍😍I found a small black spot inside the monocular, but I’m sure it was just a one-time mistake, and that’s why I still highly recommend buying their products😍😍😍

It seems to be an ok telescope. There isn't anything wrong with with it, I guess I am used to the old time spyglass type telescope.

I purchased this for bird watching at my backyard feeders.After purchasing and returning several spotting scopes, because the feeder distance is too close for a scope to focus , I thought I would give this little monocular a try. Wearing eyeglasses, by time I focus binoculars the birds have had their snack and flown off.This monocular is prefect! Lightweight, easy to focus with adjustment using one finger . I can focus on my feeder at 20 feet away quickly turn to the squirrels on my fence at 60 ft. It is powerful enough to focus and read the street name sign 3 houses away. The carrying case is not padded but nice for the price, carrying strap is light weight and not bulky or cumbersome on hand, the lense cap is fastened with a small strap, also can mount on a tripod . I have not tried the tripod as the monocular is very light weight and easy to use with one hand . It is small and sits easily on my window sill.This is perfect for back yard bird viewing and I highly recommend .

I use it when I trail ride. I works pretty well.
