Would electronic wind instruments be allowed in benchrest competition? Perhaps a couple of ultrasonic anemometers with a PC to calculate bullet defelection directly in real time. Or a scintillation anemometer which doesn't requires any dowrange equipment to give two dimenstion wind information over the entire trajectory. It wouldl be a scaled down version of the instrument used on Abrams tanks. It's just an optical device to mesure air movment simiar to a human watching "mirage" but with high precision amd speed.
