FIELD: weapons and ammunition.
SUBSTANCE: non-discrete passive device of taking lead is characterised by a pair of lines located opposite each other with respect to a vertical axis and having such curvature that the angular distance from the vertical axis to each of the lines at the level of any angle of sighting is equal to the angular size of lead to the target moving at a certain speed at a certain angle to the direction of shooting at the firing range for this angle of sighting adjusted for derivation.
EFFECT: avoiding the need to remember or carry a table of lead and select the required lead from the number of labels that ensures rapid taking of lead and maximum probability of hitting a target moving at an angle to the direction of shooting, throughout the depth of the sighting distance without the use of active means of measurement, ie secretly.
