Carl Zeiss Expands Into The Rangefinder Market with Another Global First: The Victory 8x26 T* PRF – a Lightweight, Compact Laser Rangefinder with BIS Ballistic Information System

Carl Zeiss introduces the Victory 8x26 T* PRF  --  the world’s first premium monocular with digital laser rangefinder, LED display and integrated Ballistic Information System -BIS.  This monocular is ideal for hunters who demand optical excellence, precise rangefinding and accurate holdover information from a single, compact unit.    


Lightweight and easy to use, the Victory 8x26 T* PRF provides ranging from 10 to 1,300 yards using an invisible, eyesafe laser beam.  Its high measuring accuracy of ± 1 yard at ranges up to 600 yards and ± 0.5% at ranges beyond 600 yards makes it a must have for the most serious hunters.  And it’s fast.  Measurements are displayed within fractions of a second and wide variations in temperature will not affect the measuring accuracy when used in temperatures between 14° to 122° F.    One of the prime features of this high-tech unit is its Ballistic Information System – BIS which determines the holdover (how many inches above or below the target the shooter needs to aim at a given distance), thus greatly increasing the chances of an

accurate shot.


The Victory PRF’s 330 ft. field of view and 8x magnification, combined with Carl Zeiss’ advanced  technology, help make it possible to observe and range even smaller details at greater distances.  The Victory PRF features a high-performance, two-element achromat in the 26mm objective lens.  This sophisticated optical design, combined with Carl Zeiss’ scratch resistant and highly transparent T* lens coating, increases light transmission and reduces stray light to a minimum.


The high contrast, resolution and image brightness is also a result of the Victory PRF’s red LED (light emitting diode) display which features automatic brightness control to self-adjust to varying light conditions.  The benefit: the Victory PRF’s LED display is significantly easier to read all day and especially when the light is dim and the background is dark, thanks to the red illuminated display vs. the dark symbols used in standard LCD’s (liquid crystal display) found in most of today’s rangefinders.   Furthermore, monocular laser rangefinders equipped with standard, light-absorbing LCD displays have a highly reduced light transmittance of only 50% or less, due to their operating principle based on polarization, which represents a significant disadvantage for hunters, especially in twilight.  


Operating the Rangefinder

The rangefinder can be easily set to yards or meters and can also be operated in a scan mode for fast repeated measurements on small or moving targets. A unique feature of the Victory PRF is the “one- touch” principle. Pressing the measuring button activates the red LED reticle and when released, the distance is immediately measured and displayed.  This produces less shaking than having to push a button twice as one must do with most other rangefinders on the market, thus reducing the chances of a blurred image or inaccurate distance and holdover value.


BIS™ Ballistic Information System

The BIS (Ballistic Information System), working in unison with the laser rangefinder, provides accurate holdover information for 6 different common ballistic trajectories based on the most popular hunting cartridges. Hunters can access the BIS calculator on the Carl Zeiss website at to view an extensive munitions database that will help them select the setting in the Victory PRF that most closely matches the ballistic curve for their particular load.   The BIS can also be set to work with 100 yard or 200 yard sight-in distances.  If the BIS is engaged, the hunter will see two measurements in rapid succession.  The first reading will show the distance to the target and the second will indicate the holdover.   For example, a second reading of H 8 means the hunter must aim 8 inches high to hit the target accurately at the given distance.


Mechanical and ergonomic design

The shockproof, lightweight housing is made of robust polycarbonate that is partially rubber-armored, making it particularly easy to grip. The large measuring button is positioned ergonomically and can be quickly operated, even with gloves. &

Zeiss' New Victory RF Binocular/Laser Rangefinder
Not your ordinary bino
Now that Carl Zeiss has successfully implemented laser rangefinding technology into its Diarange riflescope models, the company will turn to integrating it into observation instruments.

The Victory 8x45 T* RF and Victory 10x45 T* RF binoculars not only features very bright and powerful optics with LED displays, its integrated BIS ballistic information system also delivers the information required to correct the holdover in a fraction of a second.
Additional important features include ease of use and informative, not overloaded display concept - all in an ergonomically design for comfortable handling.

One-Touch concept
  • Easy-to-activate, fast and precise measurement.
  • Press the RANGEFINDER button:
    The LED target mark becomes active.
  • Release the RANGEFINDER button:
    The measurement is performed and the distance displayed..
Victory RF
Ballistic Information System BIS™
The bullet drop resp. the holdover (H) depends on the shooting distance and the trajectory (ballistic curve) of the ammunition. If these infos are known the holdover can be determined. This calculation is done by the integrated Ballistic-Information-System by Carl Zeiss. After measuring the distance the Victory RF models display not only the range but also the holdover.

The selection of the appropriate program for the calculation can be done easily in 3 steps:
  1. What measuring unit is used?
    Choose between "meter" and "yard".
  2. What is the sight in distance?
    Choose between 100 m and GEE (if meter is used as unit), or 100 yd and 200 yd (if yard is the measuring unit).
  3. Which one of a set of ballistic curves fits best to the trajectory of the ammunition used?
    Compare your ammunition's data with the curves in the instruction manual and select the appropriate one.
Ballistic programs for using BIS™
All ballistic curves for selecting the right program.

This selection of the program (e.g. EU 4) is made using the SET button.

Due to the ballistic program the calculated holdover (correction value for the aiming point) is displayed approx. 1 sec after the range. A display "H32" e.g. means that higher aiming is required with the holdover of 32 cm, if meter is selected as measuring unit. When using yard as unit the holdover is displayed in inch.

Please note
The Ballistic Information System BIS™ is not to be used as a replacement for the hunter's assessment of the situation, but rather to support and increase hunting safety. We recommend shooting exercises from different ranges, which can be used to check the correct match of the specifications with the actual points of impact.
