At a 10x magnification power, you are delivered with enough zoom for a sporting event or a concert. The BaK-4 prisms with a compact roof design work together with the 42-millimeter objectives and the eyepieces, providing brighter, more precise and better images.
It increases contrasts facilitating use in low-light conditions, circumstances in which it can still deliver quite detailed pictures.
Both the objectives and eyepieces are coated; the latter has a blue film coating, while the first has multiple layers and a green film. This technology is useful for observing true-to-life details at longer distances, without causing eye fatigue.
With a 307 feet field of view measured at 1000 yards, the observing area is also quite large so that you can keep track of a rapidly moving target, just as with reliable birding binoculars.

Known issues
When used many times and for more extended periods of time, the binoculars can sometimes come apart – this is because one of the screws keeping the joints together can be untightened, resulting in the mentioned problem.
It can be solved at home provided you have a matching screwdriver, but customers considered it annoying.
Another minor disadvantage is that at long distances the clarity decreases and it is harder to focus, but this issue does not affect their intended purpose as sports or concert binoculars.
