I use a home made set of flags as of a couple days ago.
I use engineers tape (plastic, 1" wide, used for marking survey stakes), 24" in length to start. Today I plan to calibrate the ribbons with a wind speed meter by cutting them until they show wind speed I want to work with viewing them at the 90º & 45º angles. I hope to put a tad-bit of Duct Tape at the very end to help in calibration.
Never done this before but in theory, it should work...me thinks?
Just an old broken rake handle I saved for something, put a spike on the bottom and the screw attachment on top, reinforced the top with some Gorilla tape folded over the yellow and punched a hole for the screw.
I'm an old'Fart...old'Skool...like to make what I can instead of buying.
Set three of them, view from my bench at 50 yards...dang things don't agree at times, guess that's the fun in reading/doping for wind.
I joined up here today to get in on the Harrell's Tuners conversation...I'm new to .22lr BR, bought this used CZ452 to play with here at home, I'm retired...am a long time BrassStuffer in centerfire and like this RabbitHole of .22lr. Good hobby in my retirement.
Made myself a home made bench & have been trying to learn about this game...don't compete against anyone but myself.
I have tinkered with this tuner with a limited amount of the Eley 'tenex' & 'Match', followed directions (sort-of) and have some experience in tuning...did an overall test shooting of various settings over the entire spread of the tuner adjustments...
Then gone on to test at various settings on both sides of the preliminary settings...
Also have been getting data on the 'bare barrel' with the tuner removed...will repeat this also with this new batch of ammo I'll pick up today...
I think this tuner works but now have a new lot of Eley Match and would like to find the most efficient tuning method for this 50 yard range. Can't test at 100 yards until I build an elevated shooting bench in my East Pasture (that'll be down the road), I figure I have plenty of work to do at the 50.
Never been a part of this forum, if I've hijacked this thread with this response, please forgive and I'll remove my post.
