desertcart.com : Gosky 12x55 HD Monocular Telescope with BAK4 Prism & FMC Lens, Lightweight with Smartphone Adapter - For Bird Watching, Hunting, Hiking, Traveling : Electronics

Review: More Than Excellent for the Price - I’ve been an avid amateur photographer most of my life, owning expensive well-known equipment as well as taking a flier on not so well known equipment, including a fair number of monoculars and binoculars. I was intrigued by the specs on this 12x55 Gosky monocular and for the price thought it well worth ordering. I was surprised and quite pleased when it arrived. It’s essentially the right weight, size, brightness, ease of focus and accuracy of focus. It’s well-made and easy to hold while using the same hand to operate the top focus wheel, which is continuous, very smooth and does not rush through the places you may wish to stop the focus for the picture you want. I use desertcart’s return policy and send things back that I don’t like, and in my opinion, this is a keeper. The holder that comes with it for taking a picture with your smartphone through the monocular looked a little daunting, but when I got to the point of actually setting up my smartphone in it -- when you’ve done it once it’s quite simple, and after you’ve tightened the unit at the right place so its center hole is properly over your phone’s camera lens (easy to do because you’re looking at your phone screen while positioning it), then the next time you want to take pictures, you put the phone in the holder, slip the entire unit over the rear lens and it’s in the right position for pictures. Then while it’s on the monocular, you’re always looking at your phone screen to see where the monocular is pointing and the way the monocular focus wheel is adjusting, as well as being able to manipulate your phone’s zoom, or any other photo/video feature on your phone to your liking in connection with the picture you’re about to take. You can of course do that either hand-held or with the monocular on your tripod. In my view, the monocular alone is definitely worth the price and the five stars. In addition to Gosky’s smartphone attachment, I’ve added two things to their package which I think enhance its use. They’re both purchasable on desertcart. The first addition is to remedy what may be an issue for some (including me). The rear lens cap is completely removed from the monocular when it’s in use. (The front lens cap stays attached and drops down out of the way.) The issue is of course is what to do with the removed rear lens cap when using the monocular. For me, sooner or later, I’ll be distracted trying to get a picture, and when I’m done, I won’t have the slightest idea what I did with the cap. So I bought on desertcart a small package of Altura Lens Cap Holder Keepers which consist of an elastic circular strap that can be slipped around the front of the monocular and a nylon tether that reaches to the back lens cap and sticks to it with a small circular adhesive tab. Thus, you can just pull the cap off and let it hang from the monocular, or pull off the elastic strap with tethered cap and, for instance, put the elastic around your wrist. Altura Lens Cap Holder Keeper . The second addition is a three-item package from CamKix, consisting of: (1) a small hand-held button (Bluetooth paired to your smartphone, iPhone or android) attached to a wrist strap, that will activate the shutter for photo/video so you don’t have to press anything on your smart phone when it’s attached to the monocular (reducing any person-made vibration); (2) a 7 ½ inch hand-held monopole that screws into the monocular for convenience, plus it can also be opened into a (surprisingly sturdy) table-tripod which can be used for a smartphone by (3) using the included screw-on holder for your smart phone (group pictures of friends, etc.), further, the smartphone can also be used that way on the monopole just by shutting the tripod.

Review: Bought the 12x55 and 15x55, and love them both! - I’ve used binoculars for decades, from small opera glasses for the theater to large, expensive binoculars for sailing. For the most part I found them cumbersome and hard to focus through both lenses. Often I’d find myself closing one eye and viewing through one lens to simplify the situation. In other words, using them as monoculars. Recently I began watching an eagle nest about 600’ away and 150’ high and figured I’d try a monocular. After reading many reviews I decided to purchase the 12x55 Gosky HD and finally fell in love with a scope. I can watch birds and squirrels 5’ outside my window as well as get a detailed closeup of the distant eagle chicks, and the images are bright and clear. I find the monocular easy to hold, and I’m able to focus on the viewpoint very quickly and maintain the position easily. In fact, I was so happy with the 12x55 I decided to purchase the 15x55 for an even closer view. Both monoculars look identical, come with the same accessories and are identical weights - 13.8 oz with the hand strap. The focus wheels are easy to adjust, the front eye cover is attached to the scope, and the hand strap connects the back eye cover so neither cover can go missing. Each size is great for most uses, though the 15x55 might give a slight edge for long distances and the 12x55 for really close viewing. I can keep the 12x at home and the 15x in the car. Right now I’m using the monoculars for hand viewing and can’t say how well the phone attachment or tripod work. I also can’t add anything about the waterproofing. But so far I’m very happy with both purchases.

## Features

- 12X LONG-RANGE DETAIL & 352 FT WIDE VIEW : The 12x magnification brings distant subjects closer, while the wide 352 ft/1,000 yds field of view provides more visual coverage for easier target location and tracking. It balances long-range detail with practical handheld viewing for bird watching, wildlife observation, sporting events, sightseeing, and travel.
- 55MM LARGE OBJECTIVE - BRIGHTER, MORE COMFORTABLE VIEWING : The large 55mm objective lens gathers more available light, while the 4.58mm exit pupil delivers a fuller light beam to the eye. This helps maintain brightness and visible detail in daylight, cloudy weather, shaded areas, dawn, and dusk without relying on exaggerated magnification.
- 18MM BAK4 PRISM & FMC OPTICS - CLARITY BUILT INTO EVERY VIEW : The large 18mm BAK4 prism and fully multi-coated optical surfaces help improve light transmission, image contrast, and fine-detail visibility while reducing reflections. The substantial optical system delivers clearer details and more natural-looking colors than basic monoculars focused mainly on oversized specifications.
- IPX7 WATERPROOF & NITROGEN-FILLED - READY FOR OUTDOOR USE : The sealed IPX7 waterproof body helps protect the internal optics from rain, splashes, and moisture, while nitrogen filling helps reduce internal fogging during temperature changes. Rubber armor adds impact protection and provides a secure, non-slip grip in damp outdoor conditions.
- INCLUDED TRIPOD & PHONE ADAPTER - STEADIER 12X VIEWING : Use the monocular handheld for quick spotting or mount it on the included tripod for steadier extended observation. The tripod helps reduce hand shake at 12x magnification, while the adjustable smartphone adapter aligns most phones with the eyepiece for clearer photos and videos.
