Oops all that lead splattered about the place will get fush and game going nuts when they find out.

While initially I thought this was pretty awesome. I actually don't like it at all. And you cannot turn off the function of it taking temp and pressure into account in the EHR corrected range.

If you keep the range finder in your chest pocket for example the temp reading will be quite incorrect. Apparantly it can take up to 30 minutes for the temp to stablise.

To get a technically better ballistic solution you need to be dealing with raw data. I now just use the actual line of sight range, then press the other button and get the angle. Then enter those and the temp and pressure figures into shooter app on phone. Then you know where you are and that you know that your come up will be more correct.

Of course you can test on the hill to see if you are getting the same come ups using both methods.

If anyone wants to read more about the 1600-B also taking pressure and temp into account for the EHR, have a read thru this thread, covers it well. need help on the leica 1600b - Page 2 - Long Range Hunting Online Magazine

cheers GWH, will read further on this later. interesting points.

i think i should be reasonably safe as i have attached the r/f pouch to the left side of my sitka bino bivvy with some chicago screws. it sits clear of my body (just) so may pick up a degree or two max, or maybe nothing at all. i won't be pushing super long ranges either, sub 500y.

My binos have this built in. Hopefully arriving next week. This has been helpfull
