Dotman the glass in the swaros are quite a bit better in my opinion. Something to consider is the light transmission is different in each barrel on the Leica do to the display. Don't quote me but I believe one was 87% and the other in the 90% range so after long periods of glassing you might get a little strain. Also there is a noticeable tint when comparing the two. Some done mind and you would get use to it but I prefer the swarovision. I don't like rangefinding binos but if I was to buy one I think the Leica is the best... just my .02
On a sheep mountain in the NWT 3 months ago I compared my Swarovision 10x42 ELs with the guide's Leica Geovid HD-B 10x42s. I was very impressed with the Leica depth of focus and clarity+++++. The overall size of the Leica is bigger, wider and heavier than the Swaros--------. I've been semi-interested in buying a pair of the Leicas that will angle compensate at bowhunting yardage. I think they are that good, but wouldn't sell the Swaros until I had thoroughly selected the Leica as my choice with enough miles on them to confidently be sure of the switch. Note that I like Leica's glass and use an old Ultravid 8x32 (pre-HD) for shorter distance hunting and a Geovid 15x56 on the tripod in the wide open spaces. They agree with me. That said my Swaro ELs and spotter are excellent and I really don't have a great reason to leave the ELs. Good luck with your choice!
I'm not sure if that info is listed but will give my Leica rep a call and get the specs on the exact light transmission.
I run the HD-B 2000 edition and couldn't be happier. Spot on to 1000 with my .300 win mag data. Shot my sitka blacktail a couple of weeks ago at 410 yards, downhill at about 30 degree angle. I have it set to 1/10 clicks meaning I have a Mil Scope and it is 1/10 mil. (Vortex PST).
Range...410 yards...scope shows C-17...17 clicks....click scope 17 clicks, squeeze the trigger....dead deer.
Pretty easy schmeezy. I have taken it all the way to 1000 and have compared the binos to my ballistic calculator and ballistic cards and it is spot on.
I was on the fence with buying the binos as the electronic component scared me but now I could imagine hunting without them. The clarity is Alpha...plain and simple. For my eyes I can't tell the difference between the Leica and Swaro...Leica is just heads and tails above everyone else with the ballistic software. The software was created by Gunwerks and is the same as used in the G7 rangefinder. Gunwerks limits the range on the licensed software to 1200 yards for ballistic purposes on the new binos. Mine is only 1000 for ballistic applications...plenty for me. The binos will range much further but won't compute beyond the 1000 (again mine are the older version) but you can still compute dope if you have a program to do so.
