A sure long-range shot begins with Carl Zeiss. You’ll certainly finish it off. Carl Zeiss helps you with simple and precise ballistic solutions for riflescopes and binoculars. The bullet drop compensation (ASV) mechanically compensates for bullet drop and is extremely accurate. Select range and take aim: that’s it. The Rapid-Z® reticle shows you the holdover points for a sure shot. The BIS® in your rangefinder determines the centimetres higher you need to hold your load. All solutions provide for a precise, expert long-range shot.
For hunting over short distances of between 50 m and 150 m the themes of "ballistics" and "bullet drop" play a fairly insignificant role. However, shooting at long range is a different matter altogether. Without you, as marksman, compensating for the bullet drop there is no chance of precision shooting at long range, and therefore no guarantee of hunting success. In order to correct this situation the first thing to do is to estimate - or better still, measure the distance. For this you can use the ZEISS laser rangefinder, which gives you the accuracy to make your long-range shot.
The innovative laser system of the ZEISS Victory RF (Rangefinder) binoculars and the Victory Diarange riflescopes allows you to measure with speed and precision distances of well over 1000 m. Knowing the distance gives you confidence in deciding whether or not to make the shot and how to compensate for the bullet drop. You are in control of the situation and can focus completely on the shot itself.
The measurement is made when the device sends short impulses from an invisible (infrared) laser light that is safe for the eyes. The finely bundled beam of light hits the target in your sights and is reflected. The returning light, the "echo", is picked up by the lens and registered by sensors inside the device. It is not the actual distance that is measured but the time between sending and receiving the laser beam. A microprocessor uses this time to calculate the distance to the exact metre and in a fraction of a second this is shown on the display in the eyepiece.
By pressing a button on the binoculars the target mark is first superimposed. The actual measurement is taken by pressing the button again - or with ZEISS RF products, releasing it .This gives rapid results and enables calmer target acquisition, optimised to ensure a successful hunt.
Knowing the distance to the target is very important for any hunter. This automatically raises the question of what level of bullet drop there will be, based on the distance to the target and how to compensate for it. Carl Zeiss is the only company to offer three different solutions to this problem. You can choose the option that best suits your requirements and preferences and then you will be ready to enjoy successful hunting in wide open terrain!
Of the three different ballistics solutions, the ASV bullet drop compensator is the most intuitive and therefore the most secure - which is why it is chosen by so many hunters all over the world. Simply turn the ASV knob to the measured distance and aim accurately, without counting clicks or estimating the holdover position, whatever the magnification.
The choice of magnification is the most fundamental difference to theRapid-Z® reticle. This system, with different holdover lines, may be quicker in practice but it does depend on the magnification. It is faster because you don't have to make any mechanical adjustments, such as twisting the reticle.
TheBIS® system is a totally unique system: integrated in the scope, it provides exact information about distance and an indication of how far you need to hold over to compensate for the bullet drop. You can use this information for your next long-range shot. The Victory RF and PRF products are innovative devices, brilliantly combining scope, rangefinder and ballistics calculator in one.
The bullet drop compensator (ASV or ASV+) from Carl Zeiss is probably the most intuitive ballistic solution on the market- easy to use and exceptionally precise. The knob normally used to adjust the height is replaced by a non-slip adjuster ring with a distance scale. Before taking your shot simply turn the ASV to the measured distance - and aim accurately. It has never been easier to overcome the problem of long-range shooting.
Your rifle can be sighted in to 100 m. You can then select from various distance rings (or films) to compensate for the different bullet trajectory paths. For a high speed bullet with a drop of 30 cm at 300 m, for example, you might choose a ring that can be adjusted from 100 m to 300 m in exactly 10 clicks ( = 30 cm at 300 m). Bullets with a greater drop will need a more spread out scale.
In our download section we offer you a free software download that contains the information for around 1,500 different loads. Simply choose the calibre and bullet type and the programme will show you which ASV ring or film to choose.
To adjust the ASV for aiming over longer distances simply lift the non-slip knob slightly and turn it. When it is released it will click back into place. In this way you can avoid any inadvertent adjustments. At 100 m the ASV has a lock for ease of handling in the dark. You can rely on the most intuitive ballistic solutions on the market.

The Rapid-Z® reticles are the fastest ballistic solutions on the market. Use the holdover lines for distances up to 500 m (Rapid-Z® 5) or 700 m with the Rapid-Z® 7, which correspond to the bullet drop for the different distances. After estimating or measuring the distance you don't need to sight the target using the centre of the crosshairs but instead simply using the corresponding indexed holdover lines. An exactly defined high shot! Superbly simply and extremely quick.
The reticle sits in the second image plane, in other words the distance from the target depends on the magnification. That is what you use to match the holdover lines to the various ballistics. This means that according to your ammunition or bullet trajectory path you set your riflescope to a certain magnification - and then the holdover lines will correspond to the bullet drop. Simply enter the type of riflescope and ammunition into the free software available on the Carl Zeiss Sports Optics homepage and it will give you the correct level of magnification.
In the case of typical high speed loads, designed for longer distances, you will require a higher magnification. With heavier, slower loads you need to select a lower level of magnification to compensate for the bullet drop.
All Rapid-Z® reticles have additional markings to estimate the influence of any side winds. This is yet another aid for long-range shooting.
A normal laser rangefinder shows you the distance to your target. Naturally that is important - but this information is not enough on its own to answer the next question: what bullet drop can I expect? This question is answered in full by the ballistic information system BIS®, which is integrated in the ZEISS Victory RF binoculars and the monocular Victory PRF.
In order for this to function properly you need to "programme" the device with your bullet details. You have a choice of 24 different programmes, and your rifle can be sighted in to 100m or the most favourable zeroing range (with 4 cm high shot at 100 m), as you wish. On the Carl Zeiss Sports Optics homepage you will also find free software with around 1,500 loads, which will tell you which programme to use.
Once you have chosen this programme via the SET button on the device and the range has been found, the display on the binoculars will show you both the range and the bullet drop, and therefore the holdover point correction for the shot. Quick - simple - and a significant boost to successful aiming.
