After a lot of research and some input from various hunter friends of mine, I settled on these Luna Optics binoculars. The original batteries will give you some good hours of fun, but I also purchased rechargeable for this ... you can also charge with cord. These are great for watching wildlife at night, which was my reason for purchase. I have seen a lot going on in my yard !!! There is definitely a bit of a learning curve, but once you get familiar with the buttons, it really is easy !! So glad I purchased these !!
