Jim, when you get below a 4mm exit pupil optics lose usefulness quick. I'm not knocking Nikon products as I have a Monarch scope I like. The tiny binocular aren't worth much. I used a small binocular much like yours from several years and when I started wearing glasses I bought a better binocular. I had no idea what I was missing. Yes, the pocket biocular will work, in good light but not too well late or early in the day or on a dim day. You can get a poro style binocular for around $100 that will have you leaving that pocket binocular home. Using a harness made for carrying binoculars is the way to go IMHO.
