The fine difference: ASV and the improved version ASV+

The idea behind the bullet drop compensation ASV is to achieve accurate aiming at all times. How does it work? You use the height adjustment of your riflescope. Too complicated? Not with the ASV, which adjusts the elevation for the hunter. A sort of "distance scale" of 100 to 400 or, depending on the load used, even 600 metres replaces the linear scale with click markings. For a bullet that falls, for example, 12 cm over 200 metres six clicks will give a "2" (for 200 m), 15 clicks will give a "3" (for 300 m) and so on - and naturally all with the corresponding interim markings.

The hunter only has to estimate the distance from his target - or, better still, measure it - then set the distance on the bullet drop compensator ASV and take accurate aim.

Various distance scales are available for different bullet drop curves. One thing is clear: a .270 WSM drops significantly less than a 9.3x62. Using tables or the free online ballistics programme on the Carl Zeiss Sports Optics homepage you can select the scale that comes closest to the trajectory of your chosen bullet type.

A successful principle well thought out.

The original ASV offers five different foils that are stuck onto the ASV elevation turret. The new, improved bullet drop compensation ASV+ has nine different distance scales to cover a larger range of ballistic curves - particularly useful when you need to take your shot in haste. The fine divisions allow even more exact adjustments to be made to the different trajectories, which makes the ASV+ even more precise. Instead of using adhesive foils they come with ten high quality metal rings (one linear scale and nine distance scales), which can be quickly exchanged by the user.


The ASV+ is an innovation that is not just available for the new VICTORY HT riflescopes. It can also be retrofitted to most earlier models of the VM/V, Victory and Classic Series.
