This little gadget gives the wind mph in settings of Max, Min, and average speed. It also gives Temp in the same respect. Has an "omnidirectional bezel" meaning you can set it up facing any direction and it will read. Can always keep the screen facing you!
I have gone leaps and bounds in my windage adjustment accuracy. I ran my bullet through a cheap ballistics calculator software a few months ago. Found the inches in wind adjustment for the various yards and wind speed. Now, I always know the speed and in turn can make the correct windage adjustments.
For hunting purposes, I set it up for 10-15 min as I wait for the Sun to rise, or when getting things together. Find the average MPH and the direction and I'm off with the settings in mind.
Oh, and you will be amazed how much you overestimate the speed of the wind!
So where do you get them?
Oh...I got mine from an aeronautics web site. Aircraft Spruce $ Specialty Co. Cheapest price I found in respects to shipping. $126 total as of 9 Jul 01.
A good piece of equipment!
