Multifunction centrer drive The combination knob for the Leica center drive feature performs two important functions : diopter com- pensation 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.
LED displays in rangefinders The actively glowing LED displays in
ADC™ (Automatic Diopter Compensation) ADC™ (Automatic Diopter Compensation) is the eminent innovation in Duovid binoculars. ADC™ main- tains 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).
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. Press- ing 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 dis- plays 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

Removable, sliding eyecups with two click stops A newly de- signed 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 indi- vidually (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.
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 inte- grated 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.
