The most important feature for me about this monocular is its being compact and lightweight, so it doesnt make you feel uncomfortable when mounted on the head or on the helmet. Also it has the low battery indicators, which is also very useful for me as at times its long hours that Im using the device, so it can be prevented from the unexpected switching off. It is waterproof as well.
I am really satisfied with this monocular, as I can use it comfortably even in the most rough conditions.
