Because the Whiz Wheel was designed for military snipers, there is also a moving target window for calculating leads. Operation is the same as for elevation corrections. There will be some math required, as only a 10 mph wind correction is shown.
1 William Shakespeare would have attended King Edward VI Grammar School in Stratford-upon-Avon from the age of 7 in 1571 and left school and formal education when he was fourteen in 1578.
Although we have no record of Shakespeare attending the school, thanks to the official position (alderman) held by his father John Shakespeare, it seems likely that he would have decided to educate young William at the school which was under the care of Stratford's governing body.
