I was finally able to get some good info how the vertically oriented beam divergence works and if it works at longer ranges from a very reputable source that has many of these units sent to him for testing. The basics of what he found are mentioned in post #2 above. Since he did all the testing and has been using the EL Range since he hasn't had a need to use his Vectronix or a Russian Navy (I think it was) rangefinder. In vast majority of real hunting situations, it sounds like he's generally found this unit to range out to 2K+
I now have an EL Range on order being sent to Outdoorsmans to have there tripod adapter stud installed and then it'll be sent to me. The tripod adapter (u may know) will then let you attach a plate from any tripod with 1/4-20 threads to it. I've always been told that glassing with binocs from a tripod is a game changer (finder).
Another post with good info and links, I think:

Jon A brings up some good points in the above thread, the same that concerned me, but NZ longranger assures me he's not had difficulty with this feature and that the EL range is ranging much more reliably and further than the competition from his testing.
Only thing that can beat it is the Vectronix. His experience is that only the EL Range and Vectronix will reliably range to a mile in bright light. For reducing weight and bulk for backpacking (EL is apparently quite a bit less bulky than it's competition), it seems like the way to go as it's rangefinder will work for the vast majority of us longrange hunters 99.9% of the time, I think.

From above review: "A key feature of the EL Range is the light transmission figure
of 91% through the lenses. Normally in a pair of binoculars
where a range finding unit is incorporated there is a drop off in
light transmission because the mechanism partly blocks light
through the lens. For Leica's newer HD Geovids, the figure
given by Swarovski is 77% for the left side and 79% for the
right. In the more expensive Zeiss Victory RF the figure is left
85% and right 74%." And: ". The EL's gave me nearly ten minutes more
glassing time than the Geovids. The Geovids I was using were
not the latest HD model which is reportedly better. This is
where the Swarovski's 91% light transmission really comes into
its own."
