ARKEN ZULUS RANGE FINDING
Ranging Targets With The ZULUS
If you have the ZULUS with built in laser range finder (LRF) , then ranging your target is as easy as pushing that button on the back left side of the housing. There is a red anodized aluminum circle around the rubber button. Press it once and the built in laser range finder will constantly range at whatever you point the ZULUS at. A small open crosshair will show up independent of your normal aiming reticle. The LRF reticle will be red. See photo below.
Depending on the ambient lighting and distance of your target you might be able to see the LRF infrared beam. It is an oval shaped light. If your ZULUS is set to day mode with full color, then the LRF pulse will look like a dark pink, see photo below. If you are using the night mode then the image is black and white so the LRF pulse will just be white looking. It is easier to see the LRF infrared pulse using night mode. You can then simply point the IR beam at the object you want to range. See how high the IR beam is from the aiming reticle in the photo below?
It is important to know that the LRF pulse is independent of your aiming reticle and magnification. As you zoom in, the LRF reticle stays in place so it might be off the screen outside the viewable image you are looking at. Lower the magnification and you can pick up the LRF reticle again. As mentioned earlier you may still be able to see the infrared beam with night mode. The darker it is, the easier it is to see the IR beam. Make sure when you are ranging you are using the LRF reticle or you are aiming the actual LRF infrared beam. Otherwise you will get an incorrect reading.
If you see “RANGING ERROR” that is a notification that the ZULUS was unable to range what you are trying to measure. This could be for a number of reasons. One reason is if the object you are ranging is too close or too far away. The ZULUS LRF can range up to 1200 yards in perfect conditions. Another problem could be the target you are trying to range is not reflective enough to bounce the IR beam back to the ZULUS LRF. This is a common problem for many LRF, not just the ZULUS.
