Thanks for the feedback. If I did my math correct 980 yards at 8 degress should have given a true horizontal distance of 970. At 8 degrees the change from line of sight to horizontal distance is right at 1%. I am not sure what the accuracy of these rangefinders are and if 1% is as close as they will get?
I've been running my 1600 for the past year and absolutely love it. I shoot a 6.5x47 Lapua running the Berger 130 VLD @ 2970 so Ballistic Curve #3 fits the bill. I shoot it out to 500 yds and as long as I do my part, I hit everything. Simply range, count 1-2 seconds and the drop in MOA comes up. I then either hold over using my NF NP-R1 reticle or dial and clang goes the steel. I lent it to my partner and he used it yesterday with his AR15 with a 69 gr Match Burner and used curve #5. He hit everything out to 600 with it. It's rated to 550 but was successful using out that far. I trust this thing so much I just got the new 1600-B but haven't tested it as I'm out of the state. When I get back on the 22nd I've got a few days to verify it's worth 'cause on the 27th, my partner and I are competing in a 24hr Sniper Challenge in the No. Utah desert mtns where temps can range from 40 to 100, altitudes from 4500 to 7000 and angles up to 60 deg. From what I've read, when we arrive at a COF, we find and range reactive steel targets. We're given a less than generous time to set up and hit each each target. I don't want to have to worry about pulling out the Kestrel, EXBAL, note book, etc which will all eat up time. With this thing, it's simply point, range, dial and shoot.
I bought the 1600 B and have tried it out briefly. On the positive side, it has a hell of a range, 1250 yds in haze and looking partially into the sun, almost 1900 yds on foliage on an overcast morning. As for it's other functions, it seems you can program it to display holdover OR compensate for vertical angle (what it calls Equivilant Horizontal Range), not both. After selecting the ballistic curve, zero range and units of holdover (in my case 1/4 moa) it works fine for horizantal but does not compensate for angle. Then when I go back into program mode to set it to display EHr, it cancels out the previously entered settings. The instructions are a little vague on this (or I'm a little dumb) but I can't seem to get this figured out.
These are all pretty much horizontal distances. Will try and get out this evening to the canyon behind my house and range some "up" angle items.
Found one target at 877 yds and it would not give me a firing solution. The spec sheet in 800m/875 yds is max for firing solutions. Was pleased I got the one @ 873 yds.
I used the 100 yd zero and the when looking for the appropriate 100 yd zero reference chart in the back of the booklet, on pg 181, it gave the 12 curves as EU (European) for meters instead of US (United States) for yards. A simple misprint but had I not known what I was looking for, i'd have been lost and frustrated waiting for Leica CS to open up Monday am. The old 1600 manual only goes to 300 yds while the new 1600-B goes to 500 yds for the zero range charts.
Looking at my results and the zero range charts, it seems everything is hunky dorrie until around 500+ yds at which time the two curves seem to depart a little more with increasing distance; as much as 2.75 moa at 873 yds. It may be I need to use curve #2, a bit flatter curve. I'll more this evening. At 300 yds my Shooter program says 9.76" low and the chart says 9.6". Yet at 500 yds, Shooter says 41.1" and chart = 45.
Curve #2 @ 500 says 42.1.
I'm probably confusing the heck out of everyone with this chart stuff. The chart is used to help the user decide which curve to use. Curve #3 is pretty much spot on out to about 500 yds; beyond is where the divergence starts.
You're not confusing at all. You make way better sense than the 1600B manual. I confirmed this afternoon that in the mode that gives you the amount of holdover, it's not compensating for virtical angle. Every time I enter the EHr mode, it cancels out the holdover display. The info on the left hand side of page 36 was written by somebody without a firm grasp of english grammer so I don't know if It's possible to have the holdover displayed while compensating for angle. If not, the they spent a whole lot of expense on programming that's pretty much worthless unless you hunt only in the flatlands.
