A mate uses a set, simply because at the time Swaro didn't do them. Remember everyones eyes are different, and my eyes don't completely agree with Leicas. Saying that though, they are a quality piece of gear and the rangefinder works superbly.
I have had my Geovids for about 6-7 yrs and have nothing bad to say about them, in fact I consider them my best hunting purchase for rifle hunting. They are bright, clear, the rangefinder seldom does not get a read in all kinds of weather and they are bombproof. For me I give them a gold star
Take them out for a test run, that's the only way to know for sure.
At first I also liked the idea of an integrated set, but after just a short period of use found that the extra 6-7 ounces on the neck wasn't worth the consolidation, especially since there is no net weight savings. It is cool being able to rapidly range while glassing, however, it just wasn't for me. The quality of the Leica set is very, very good, however, and I would recommend their's or the Swaro's if you're set on this route.
Just posted about this topic on another forum. Here you go: I've owned the Leica Geovid BRF's, the Swarovski EL Range, and the Zeiss Victory RF's. I currently have the new Leica Geovid HD - B's on order.
*Leica Geovid BRF's - Mine were lemons. Went back to Leica 3 times and never did range anything very well. I have two buddies with the BRF's and they have had no problems and love theirs. Excellent Glass. No angle comp.
*Swarovski EL Range - I bought these because they are the only of the "Big 3" with angle compensation. Awesome glass and great rangefinder unit. The downside to the Swaro's is that the minimum range is 33 yards. Not a big deal for a rifle guy, but for a bow guy in the mountains, this is not a good thing and frankly, is a big deal. The rangefinder also had some issues when the temps were below 20 degrees.
*Zeiss Victory RF's - Best rangefinder of the three by far. The beam divergence is better than the other two, but optically they are not as good as the Swaro or Leica. Mine would pick up ANYTHING and ANY yardage in ANY temperature and do it VERY fast. If angle compensation isn't a big deal, this unit is tops IMO.
Overall, you can't go wrong with any of these units. They are all optically fantastic and each ranging unit has it's own intricacies. For me, to rank them in order it would go - Zeiss, Swaro, Leica. With that said, I do have the new Leica Geovid HD- B's on order.
