Barska Colorado Reverse Porro Zoom Binoculars Well, you could do worse! Personally, I really like these binos! I have been an amateur astronomer for over 35 years and have a wealth of experience with telescopes of all kinds and binoculars. Sure, I have better binoculars than the Barska’s but for their price point, you really are getting a great deal! I actually got these not for astronomy but for terrestrial use. I wanted a decent sized aperature with a zoom feature. Most amateur astronomers will shun you away from zoom binos but I beg to differ if you only use them for land observation. First of all these cheap binos are built like a tank! The rubber exterior is well executed and feels great to hold. They are a bit heavy but sometimes this make it steady to hold than lighter weight ones. The coatings are pretty good and the objectives and eyepieces give a crisp view from 10X to 20X. Anything above that and you start to get purple fringing of the image and more difficulty focusing. I find that between 10X and 20X…

Good value if you don’t have to carry it around. I like the zoom feature. I have a viewing platform at the edge of a canyon, where I can see the ocean 4 miles in one direction, and a waterfall off a mountain plateau about the same distance the other way. In between is a forested canyon. I keep these binoculars in a waterproof container on the platform, and I can bird watch, or identify tree species across the canyon. Perfect for this, at a great price.

Excellent product for the price point I do not write many reviews but felt compelled to do so on this product. First, let me say that when I purchase a product, I evaluate price point versus quality. When I received this product, I was initially impressed with how well built these are. The lens clarity is very good at night and beyond expectations during the day. The zoom feature is a great option and I found the transition from 10x to 30 x to be very smooth. Unlike other reviewers, the clarity was very good up to 25x. Beyond that, slight distortion occurred but only in certain conditions. For example, in brighter light conditions, 30x was clear. The optics adjustments are smooth and easy to move. I also purchased the Barska tripod adapter. This made viewing at higher magnifications a far better experience. Using a tripod gave more of a telescopic feel to viewing and, lets be realistic, at 20-30x, it is difficult for the average person to hold optics steady for field viewing. I use these for hunting and while they are…
