ADC (Automatic Diopter Compensation) ADC (Automatic Diopter
Compensation) is the eminent innovation in Duovid binoculars. ADC maintains
the original diopter setting when you change the magnification (from
8 x to 12 x, or from 10 x to 15 x as the case may be).
Automatic Diopter Compensation ADC
Multifunction centrer drive The combination knob for the Leica
center drive feature performs two important functions : diopter compensation
and focusing. Because of its size, it is always easy to use
as a focusing wheel and it provides ergonomic handling and a steady
observation. The large diopter scale allows quick and convenient
setting of your personal diopter value.

Removable, sliding eyecups with two click stops A newly designed
rotating sliding eyecup is used on binocular models Duovid
50 and 42, Ultravid 50, 42 and 32 and Geovid. It can easily be
removed for cleaning at any time and it has two click stops with
which different eye relief distances (AP positions) can be set individually
(with eyeglasses = retracted ; without eyeglasses = pulled
out). With its gently cushioning rubber element it guarantees long,
relaxed observation and for eyeglass wearers it provides secure
positioning without damaging the eyeglasses. The remaining Leica
binoculars are equipped with sliding eyecups that guarantee an
optimal eye relief.
Televid dual focusing The dual focusing device
patented by Leica is incorporated in Leica spotting
scopes. Two separate focusing drums enable the
observer to perform a quick initial focusing followed
by an accurate fine focusing to obtain an image
that is always perfectly sharp.
LED displays in rangefinders The actively glowing LED displays in Rangemaster-, Pinmaster- and Geovid models employ a
sensor that automatically tailors their intensity to the prevailing ambient light at all times. This feature assures perfect legibility in
all light conditions and it especially prevents eye glare during nighttime observation.
Leica rangefinder technology – with a press of the button
Leica rangefinders distinguish themselves primarily by the
fact that they can be operated intuitively, by the excellent
legibility of their LED displays and by their bright optics. Pressing
the measuring button just once switches the instrument
on, the target sight appears in the display and the object can
now be addressed. Pressing the button a second time displays
the measured distance. By keeping the button pressed,
the instrument automatically switches to a scan mode, which
is indicated by a blinking display. The instrument now provides
continually updated measurement values. The scan mode is
especially helpful for the perfect measurement of distances
to small or rapidly moving targets.
The measurement of distances is based on an eye-safe light
pulse that is reflected by the object that is being sighted.
A microprocessor uses the time elapsed until the light pulse
has returned to compute the distance and then indicates it
in the instrument’s display.

Pinmaster primary target logic A software solution that has been developed especially for the sport of golf has been integrated
in the LEICA PINMASTER. It always evaluates the reflection of the light pulse that arrived first (“nearest echo” principle).
For example : you sight a flag pin with woods in its background. The first echo logic only evaluates the signal reflected by the
flag pin, not the signal reflected by the woods. This provides optimal results for golfing purposes, for example for checking the
improvement of one’s handicap during training, or for the groundskeeper to conduct a new survey of the greens. On the other
hand, LEICA RANGEMASTER models always evaluate the strongest signal reflection (“strongest echo” principle). In the example
cited above, they would indicate the distance to the woods. This prevents unwanted false measurements caused by shrubs and
saplings during intensive use in the field.
