I wanted to get the stabilizer image for my father, who is 87 years old. I thought this would help him focus on whatever images he would look at. He enjoys them, and uses them frequently. I borrowed them for a sailing trip, and also for a week at the beach. These are simply one of the finest, clearest specs I have ever used. My first impression in the ocean was the brightness and clarity. Precise images could be identified, and the added stabilizer eased the movement of the boats unforgiving bounce. Using the stabilizer provides clean, crisp vision, spotting ship registration numbers over a mile away, and, more importantly, solid comfirmation of bouy numbers on the first look. This low priced binocular far outperforms many expensive alternatives.
