when i wuz shooting bench rimfire, wind reading was everything with those dang round little bullets ... we used 3 flags in 50 yards !!
i had my production cnc stuff , so had some fun ...my favorites were a sharp metal stick in the ground, with a foot pusher ... a six inch long, ball-bearinged delrin spinner stick on top, with a owl-eye cheap bubble level sunk into it ( protection deep ) ...a cross hole with an arrow shaft from a arrow maker supply ... then on the arrow tip almost anything light... we used mostly surveyer's tape. oh, keep the ground stick short enough to shoot over if firing lanes are crowded ... on the arrow shaft rear, we put a ... ” fletching ” to catch the wind, painted black one side, white on reverse ... then the fletching showed direction, the angle of the tape showed velocity ...
the bubble levels were so the spinners spun easily ... i bot the bubbles by the box ...$3 each at the time ...
an alternate to the simple ground sticks were music stand bases ...3 legged ... but i preferred the sticks ...
guess what works almost as well ... a stupid sharp ground stick with a piece of yarn ... tend to wrap around the stick on a gusty day ... but cheap, fast, light ... and you can make a dozen of these in an hour.
no end to the variety ... ken
