Hmmm......
I am afraid you are going to hate me
BeeMaa (but after things are fixed you will love me
).
I agree that the gen 1 Leica Geovid-R 10x42 (part #40428) had an on-board inclinometer AND displayed EHR.
Unless I am grossly mistaken, which is possible but unlikely, both 10x42 Geovid HD-R 2700 (part #40804) and 10x42 Geovid HD-B 3000 (part # 40801) have the hardware on board to measure air pressure, air temperature and the angle (this is probably because it is cheaper for them to only manufacture one set of hardware),
but only the HD-B models have the ballistic program to use the data to display either holdover, adjustment clicks, or the equivalent horizontal range.
I hope that I am wrong, but I urge you to double check with your vendor, because I believe that I am right...
Regarding the micro SD card, FYI the "B" (Ballistic) models have 12 US and 12 Euro ballistic curves built in the unit, which have been plenty good enough for me. You would only use a micro SD card if you wanted to load the exact ballistic curve for your load. In my experience, the 12 US curves, and 3 options to set the zero distance (100, 200 and 300 yards) have been plenty good enough for me. Using preset curves US 1 and US 2 depending on what rifle and load I have out that day , the .257 Wby, .300 Wby and .340 Wby bullet path stays within 1/2 inch over or under the Leica built-in curve out to 500 yards (.257 and .300) and 450 yards (.340) which is more than I need for hunting. This one, you need not verify, I am positive that I am right
Just my S0.02 my friend
