I find binocularz can be very useful but I hate lugging them around, but this Powerful 15-55x zoom monocular is very handy to carry around and easy to use. Ideal for when I am birding, as well as for traveling/sightseeing, hunting, observation of sporting activitiez and concertz, this lens can also clip onto my phone (clip sold seperately) to improve my phone cameras zoom. From 15 x to 55x adjustable magnification levelz, this lens brings objects 15 times up to 55 timez closer in a small, portable monocular design. I always bring it to concertz and sporting eventz so I can easily see better without bulky and tacky binocularz. A fully multi-coated blue lens helps achieve outstanding performance by minimizing light reflection, increasing light transmission and brightness. I can see a distant object even when it is getting fairly dark too. With adjustable focus and fold down rubber eyecups this lens is convenient to use whether or not I am wearing my eyeglassez. It is very handy to carry around and use sometimes I even forget I have it in my pocket! Great as both a monocular and a phone lens this 15x – 55x telephoto lens is an awesome gadget to help you take better photoz and get the best view of interesting eventz.
