This investigation compared how accurately target ranges can be estimated from two modes of observation -viewing a black-and-white television TV monitor, and viewing with the unaided eye. For each mode, the subjects made four estimates at each of five distances -100, 300, 600, 800, and 1000 yards. Two conclusions were indicated 1 subjects could estimate absolute distance when viewing the TV monitor and 2 there were significant differences between the subjects constant errors in the two modes.
