Abstract
The invention relates to a binocular observation device, in particular a field glass, with two visual optical paths and with a laser distance meter with a laser transmitter and a laser receiver and with an opto-electronic display element. A part of an optical path of the laser transmitter is integrated in a first visual optical path and a part of an optical path of the laser receiver is also integrated in the first visual optical path.
