• Longrange Shooting

    Various solutions for your success

    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 BIS® in your rangefinder determines the centimetres higher you need to hold your load. All solutions provide for a precise, expert long-range shot.

     

    Measuring distances with the laser rangefinder

    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 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.

     

    Bullet drop compensation, ballistic competence

    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. 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!

  • Ballistic applications

    Differences between the two ballistics applications

    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.

    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.

  • ASV

    Bullet drop compensation features

     

     

    The bullet drop compensator (ASV, ASV+, ASV LongRange) from 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.

    Available solutions in the overview

    Below you can find the overwiew of the different bullet drop compensators (Attention: not all riflescopes can be combined with ASV). For true specialists the ASV, ASV+ and ASV LongRange are also available with side adjustment. The same technology can be used to compensate with great precision for side winds and any deviation in rotation.

    ASV LongRange (rings)

    Thanks to the larger adjusting range with 100 clicks, the ASV LongRange allows you to maintain your aim even at long distances. The different scales are on 10 easily excangebale, engraved metal rings, which are also simple and quick to install.

     

    ASV+ (rings)

    To fact that shooting distance is clearly displayed makes the ASV+ the most intuitive and therefore the most precise ballistic consept on the market. It enables a maximum operating range of distances up to 600 meters. As with the ASV LongRange, the scales are on 10 easily exchangeable, engraved metal rings, which are also simple and quick to install.

     

    ASV (foils)

    ASV comes with metal foils for different calibres, which are then bonded to the ASV turret. The adjustment button with the appropriate adhesive foil can be simply adjusted to the required distance.

     

    Usage of the ASV

     

    Adjusting the ASV lock rings on the riflescope compensates for bullet drop in order to maintain precise aiming, even at long range. The disrance is set using a fine distance scale, supplied by ZEISS for all current load types. The scale allows you to aim accurately over all hunting distances.

    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.

  • BIS®

    The BIS® ballistic information system

    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.
