Great as what it is: an affordable rangefinder... - SIG SAUER Kilo 3000 BDX 10x42 Rangefinder Binoculars

...when you compare it to against the swarosvki EL and leica Geovid HD-B 3000 (also in the same top notch quality and price is the Zeiss Victory RF, but was not able to test it. I just compared the RFs against the Zeiss victory HT - all 10x42.
The victory ht is not a RF but it's in terms of clarity, color, and low light ability is above all the other brands for my eyes
As a rangefinder the Sig performs quite well -actually better than the swaro and the leica in terms of accuracy, and only the leica beats it as getting the readings more consistent at max range.
But then it shows why it is cheaper...
There is a noticeable purple fringe, sharpness suffer a little bit too, and when it gets a bit dark, clarity is not par either. Color rendition, OOF or blur quality (as in how distractive becomes and separates the background) is also lower.
However we are talking an unit that cost on average three times less than all the others I mention; so in all, it's a remarkable RF but handicapped as a binocular.
Buy it for the RF capabilities - btw, it's a breeze to connect to the app - do not recommended for long anytime glassing use.
