great multipurpose binocular


I went whale watching with this binocular. It is surprisingly bright, easy to focus and maintain handheld visual, even with all the pitching of the boat.

Great bang for buck


I got these for my 11 year old for general use. My own binos are bigger and more expensive, but ironically, we end up using these more often, because they're lightweight and easy to carry around. They throw up a nice, bright, crisp image in the center. The focus mechanism is smooth, with no slop, and perfect fluid resistance. Every time I look through them, I think, "these were less than fifty bucks?"
