Query: Olympus Tracker 8x25 Porro Prism Compact & Lightweight Binocular

The product is as advertised and works satisfactorily. It is well made and easy to use. It is not quite as compact as I imagined. If something to slip into one's pocket is wanted, it seems that the next smaller Olympus model would be preferable.
