Measure
distances and tilts
Simple, quick and reliable
The Leica DISTO™ D3 is a
multi-functional instrument to ensure simple, quick and
reliable measurements. You can measure distances with
pinpoint accuracy – in spite of nearby obstructions –
and determine angles quickly and precisely. The small,
elegant Leica DISTO™ D3 is a reliable instrument to suit
every pocket.

Tilt measurement
The instrument's inbuilt tilt sensor quickly
and simply determines tilts up to ± 45°. The tilt sensor
can also provide you with true horizontal distances.
Reliable measurements are therefore guaranteed.
Multifunctional
end piece
Aim the instrument straight at the target point, whether
measuring out of
corners, slots or from edges: with this end piece you
are prepared for all measuring situations. The
instrument detects the end piece automatically, which
helps you avoid expensive measuring errors.
Automatic keypad
and display illumination
An built-in sensor detects if the environment is dark
and switches on the illumination of the keypad and
display. You can also measure in the dark without any
problem.
Multiple
functions
The Leica DISTO™ D3 can also calculate areas, volumes,
room dimensions and various types of Pythagorean
functions. A time delay release and enough memory for up
to 20 measurements finish off the instruments wide range
of functions – a concept designed to make your work
easier.
Indirect Pythagorean measurement
Single
Pythagorean measurement
Just two measurements are enough to indirectly calculate
the horizontal or vertical distances. It is important to
ensure the 2nd measurement is at right angles to the
target object – easy with minimum measurements.
Double
Pythagorean measurement
Using a tripod you can measure horizontal and vertical
distances. The Leica DISTO™ D3 determines the results
for you out of three measurements. Functions such as
minimum and maximum measurement help you find the
correct measuring point.
Double
Pythagorean measurement (chain values)
With three measurements you can determine
partial heights, e.g. window heights. Possible for
horizontal and vertical distances.
Indirect tilt measurement
Tilt measurement
The tilt sensor measures tilts up to ± 45° and a typical
use is for determining the pitch of a roof. When
measuring tilts, the instrument should be held in the
horizontal position (± 10°).
Horizontal
distance
The tilt measurement function allows you to determine a
horizontal distance even if the target point is not
directly visible. This is particularly useful when there
are obstructions, e.g. walls directly between you and
the target point.
Room corner angle
function
The angle in a triangle can be determined by measuring
the three sides. This function is suitable for e.g.
checking a rightangled room corner. First, measure the
two shorter sides and then take the length of the
diagonal as the third measurement. The device then
displays the room angle.
Staking out
function
Two different distances (a and b) can be
entered into the instrument and then subtracted from
specific measured lengths. This enables you to see the
direction in which the Leica DISTO™ D3 must be moved,
the display shows a direction arrow with the current
staking-out distance. At a distance of 0.1 m to the next
staking-out point the instrument gives an audible
signal.
