{{#category_index:S|shootback method}} An electromagnetic-surveying method which employs two tilted coils, each of which serves both as a transmitter and a receiver. At every station, readings are taken with each coil serving as transmitter for one and as receiver for the other. By averaging the readings, errors due to misalignment or topographic differences are essentially eliminated. Also called Crone shootback.
