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.
