just purchased myself a 1600, and was a tad confused. do I have to change the settings to show the angle corrected range or does it automatically show the correct range?

This is correct. However it doesn't matter which ballistic curve you pick, it on uses the the angle of inclination to calculate corrected distance. If you want the range finder to use atmospheric pressure, temperature and angle to calculate your shooting solution you need to select a ballistic and zero range that matches your rifle. Then it will give you a solution in either MOA, or inches of holdover. Mine has proven to be accurate within a couple of inches at the maximum distance for ballistic correction, 875 yds. I have 1 rifle that is too fast match any of the preprogrammed bal curves so I use the corrected yardage with that rifle. This has work well out 800yads as well as long as I have a turret within 2000 yes of the actual elevation.

I also don't us the included programs. Too bad Leica did not include in the design the capability to input (manual) data for the users specific ballistics.
You'll have to select EHr mode once you have selected it then when you shoot an azimuth to a target you'll get two readings back. One will be THr (True Horizontal Range) not taking the look angle into consideration and the other will be EHr (Equivalent Horizontal Range) which took the angle into consideration. EHr is what you'll dial your scope to.
example: Say you're shooting down hill on an angle at a target. You range the distance and the view finder shows a THr of 692 yards a second later it shows 581 yards that is your EHr and dial your scope for 581. BTW if you have a hundred yard difference you shot angle is really extreme. I was just using these numbers for comparison.
hope that helps,

Anyone know if there is a tutorial or video out there on the use of the 1600B?
Rick,
Its pretty straight forward. You should be able to set it up five minutes. You have to jump between the secondary button the smaller and primary button to move between steps and select the appropriate formats
Going off memory...
Pg 29 Step 1 Select US=yards EU=meters
Pg 34 Step 2 Select ball-istic profile us 1 thru us 12 whichever meets your ballistics best, if none then your out of luck or you can turn it off. Which if you do you only have a range finder it won't give you any data except atmospherics. For the sake of thisctread lets say us 1 meets your profile
Pg 35 Step 3 Select Sld "sight in distance" 100 200 300 yards
Pg 36 Step 4 Select either Ehr, Hold or MOA which if moa is selected its gonna want to know your scope adj scale 1moa, 1/3 moa, 1/4 moa or 10mm 5 mm adj
That's it- your device is ready to go.

For what it's worth I have found the EHR that the 1600B put's out is incorrect. I don't know if it's because it's tied to one of the ballistic curves or what. Getting the EHR from the Line Of Site Range is pretty simple when the angle is known. When I first got the thing and set it up using a on board ballistic curve that was close (but not) to my rifles actual curve, I just wanted to get the EHR to enter into my ballistic program.
I started noticing it was not working well when I entered the info into Shooter. So here at my ranch I have a lot of and places to use the range finder from moderate to steep angles out to about 2000 yards. I do Architectural Design work so I started taking the Line Of Site Range into Auto Cad and using the true angle verified by two different range finders would layout the EHR and check it against the EHR the 1600 would put forth. Tested at different angles and distances for a few days and they never jived....not once
Also when you take the EHR from the 1600 and enter that number into a ballistics program like Shooter it again calculates the temp pressure and all that stuff really screwing things up.
So now I just get the Line Of Site Range, Barometric Pressure and the angle with the 1600B and enter that info only into Shooter and it has worked very well.
Now if there is a pre-loaded ballistic curve in the 1600 that matches your rifle really close things might work OK for you.....good luck.
I agree with Kcebcj.
The 12 ballistic curves don't match up very well. Not sure who did the work on putting that data in the devicebut someone kick them lol or let us load our own data in the unit!!
Because of that I run the 1600 B for range ONLY and pair a Kestrel 4000NV BT with [AB on my android phone] to get my fire solutions. Sweet set up.
I got a super deal in the 1600B and the kestrel so I am no where near the cost of say a G7 br2 and IMO I have a more accruate set up. Even if I went full retail on these devices I still would be under the cost of a G7.
FYI I did see that G7 is coming out with a better beam divergence model this June. That should make a huge difference in accuracy of the unit...but the cost is gonna be $200 over the current price - ouch!
