What is a transit in navigation?
Short answer
Two charted objects observed in line, giving an exact position line without a compass
A transit (called a 'range' in North America) occurs when two identifiable charted objects are observed in line. This provides a highly accurate position line that requires no compass and is unaffected by deviation or variation. Transits are invaluable for checking compass accuracy and for pilotage.
