Can I get by using altitude correction up to 600 yards or will I miss? 2-4" of error will cause a miss. That $32 La Cross wind meter/temp is calling me. And did I mention I'm cheap.
Altitude is not the best means of measurements but out to 600 yards the margin of errors is very small. Barometric pressure is the best means, but it's not always that simple... well it's pretty simple?
I have a Krestel 4000 weather meter that I use and each time I head out to the range I have to check my local area conditions and calibrate the unit for the current and known barometric pressure. With the internet this is a quick and simple process and it takes less than a minute to calibrate my Krestel.
Best of luck.
