Review on Steiner 7x50 Navigator Pro Binoculars: Optimum Clarity, High Contrast Optics, Floating Prism System - Get the Best Sports View with Easy Auto Focus! by William Hunter

I had already decided I didn't need a compass so this model was the perfect choice. As others have pointed out. Focus once and you're done. The clarity is amazing. A very small problem. These suction cups are powerful! The obvious strength and quality certainly make up for that surprise. I expect to use these binoculars for a very long time.
