Re: Leica's New Geovid HD-B
Tried mine this week. Love optics, love rangefinder, love having input data immediately available (pressure, angle, and temperature). Not so keen on the ballistic computer. Initially, I was most put off because it only uses G1 BC and has no option to change sight height from default of nearly 2".
Biggest problem is with the zero distance. No way to transfer my usual x inches high at 100 that I input into Shooter. I thought I could fix that by conversion (e.g., 2.5" high yields zero at 280 yards). Binoculars gave me fits trying to match my Shooter output (which I trust) to Geovid read out. I finally figured out that, even though the online form for programming the card allows for zero to be set at exact yardage (like 280), binoculars still go off of 100/200/300 zero. Once I figured that out, Shooter and Geovids started matching.
So to make best use of them, I will have to tweak my zero on my rifles to correspond to a set 200 or 300 yard zero.
Only other minor gripes are: 1) I wish they would give me 1/4 MOA readings, such as 10.25, rather than whole minutes or total clicks. That is, they round off to give nearest MOA, but if 1/4 minute option is chosen, it gives total clicks, so 10.25 is either "10" or "41" for output (mil options are same way). 2) would like option of multiple trajectories to be stored on the micro SD card. And, 3) since I will have to use multiple cards for different rifles, the changing should be easier. As it is, one has to unscrew the battery compartment lid, remove battery, and use tweezers (they even send tweezers in the box) to insert a new card. I can see all kinds of potential problems trying to do that in the field. They might turn into regular binoculars in a hurry if battery cap drops into rocks/leaves/snow/mud/etc. At a minimum, there should be a tether to keep cap tied to the binocular body.
All in all, still a great tool. I will set up the computer for allowing quick eval of modest shots (eg, 500 yards or less) or steep uphill/downhill shots. Will still set up my long shots through shooter. After all, still need to account for wind, spin drift, and coriolis effect on the long shots.
If anyone else has figured a way around these problems, please post them. I would hate to have to read the manual.
