Duh! Some times are great notion.

I have a ballistics computer and a portable weather meter that gives me humitidy, wind velocity, temperature, altitude or baro pressure, etc. This along with range data from my laser R/F theoretically will give me the information to adjust my scope for any range to a PD or sqirrel.
Fundamental problem is wind direction or velocity at the shooter's location when shooting at from several to many hundreds of yards can be worthless because it doesn't reflect what is going on at the target. This can be a big problem especially where winds vary on the way to the target.
Today I was walking through the local big box electonic store and low and behold, what did I peruse. A weather station with anamometer, rain gauge, and wind direction detector. Big deal you say, so what?
Well, it occurred to me that moving this instrument down range to near the limit of it's transmitting range, say several or even many hundred yards and posting on a stick driven in the ground could theoretically give accurate down range wind information. The rain guage could be ignored.
The trouble we have is that our varmint calibers, like the .204 have bullets with BCs in the .200 range which is about like a rock. Down range wind information when combined with shooter position data could be averaged and used to improve balistic prediction.
Transmitter range would not be affected by buildings or other impeidiments, so that could improve range. When I was hunting PDs in Winter S.D. a few years back we were shooting pds at 300 to 400 yards in 18 mph winds.
The .260 did very well, the people with the .22 cal centerfires were just kidding themselves. But down range wind info would have been really helpful.
That 6.5 100 grain VHP stil hit really hard at that range even though it had a BC in the low 200s.
Would that be cheating?
