I have had 3 Swarovski EL range. The first set was the 8x42 and after I used them awhile, I opted for the 10X. Although I have been a bigger fan of 8X, I went to 10X when using the RF. After a couple years, when Leica came out with the HD-B, I tried them, thinking the Perger Porro prism would be a better image. After a couple years with the Leica’s, I went back to Swarovski as the image quality of the EL seemed superior. The rangefinder in the Leica was better, but I don’t need 1500+ yard ranging capabilities. All the ballistic data integrated into the binoculars was of no interest to me as I have my scopes with ballistic turrets.
When the Swarovision EL range came out, I got those and the laser seems to be better than the previous version. They continue to work well for me and can even range through the windshield of a truck.
I still have the Leica CRF 2700 for archery along with the Swarovski 8X32 NL pure binoculars, as the full size 10X42 are bigger than I want to have when I bow hunt.
