Last year while pig hunting in Texas, I dropped my Nicon binos and broke them in half. Told my wife I needed a new pair and she asked me what I wanted. I had been researching the combo units and decided it made a lot of sense to only carry ONE set of optics. I wanted the Swarovski's and lo and behold she bought them for me for Christmas. (What a Gal!) I have not had a chance to really use them much, but they seem to be exactly what I wanted. Crystal clear and sharp and the RF works great out to 1000 yds. Only thing I noticed is that it goes thru batteries pretty quick. I know that Swarovski is a high end set of glasses, so I expect them to perform well this fall. Sent the Nicons back and they sent me a new set of binos....these were 11 years old! Anyone else use a combo bino/RF? Like to know your experience.
