Well I decided to upgrade my Binos Old Leopold Green Ring (10X42), after going birding for the first time. Is seemed that most were using 8X42 and after some time looking though some nice 8x42 binos I said to my self-time to upgrade. So the research started and I ended up with a pair of Vortex Viper HD 8X42. At first I thought they were very nice and so did my wife. Well after looking at Hummers at first light, we both decided there must be something better. So they were returned and we had in our hands the Vortex Razor HD 8x42. Well once again we used these for a while and my wife asks why are here scopes on her rifles better than the binos. I said the Vortex Razor scope should be no better than the binos. Well we ended up ordering a second set of Razor 8x42 (This is all from Eagle Optics). Birded every chance we got. On the 20 day and not totally satisfied. Another call to Parker at Eagle Optics. I am thinking to myself that he must be tired to talking to me, anyway he suggests the Sward SLC HD 8x42 which had been phased out. So we receive them and we fall in love (my wife loves them but does not like the weight). And by this time I knew there was no way to share binos. So a quick call to (EO & Parker) explaining that we love the SLC HD, but need a pair somewhat lighter for my wife. So 2 days later we have EL SV 8X32 and the wife and loves them! Well fast forward 3 weeks and the Diopter will not stay focused on the SLC HD and you there are no more to be had. So I send them back, and now have the EL SV 8.5X42 and believe we are done! We both love the view through the SV’s and highly recommend them as well as Eagle Optics and Parker.
