Re: Swaro 8x30/Leica 10x42 brf
You are comparing two things slightly different.
I had a chance to use pete lincoln´s leica 10x42 bino/rf and compare with my swaro 8x30 slc bino/ leica rangemaster rf combo...
Distance readings were absolutely coincident; clarity with my swaro bino and the leica was about the same, and although the 10 magnification is great when you need more details on a target, the 8 x is in my opinion more comfortable.
Now the great thing about the leica 10x42 with integrated rf is that you have both things in one, which avoids the need to first spot with bino, then change to RF.. and maybe change to bino again if the target moves... and so on.. using both in one piece is great and still you may be saving some weight overall, apart from diminishing chances of a deer slipping away becuase you mess around with two things instead of one.
Contact Pete Lincoln and he´ll help you.
