Precise measurements from waterproof, high-power telescopes. AL-NIKON-AE-7. Nikon AE-7 Series auto levels feature waterproof, high-power telescopes that help you make precise measurements even in the wettest conditions. They feature a unique automatic air-dampened compensator to prevent magnetic interference, and an endless horizontal fine drive to ensure smooth, precise pointing and angular measurement. AE Series auto levels are easy to set up and easy to use. All four models can attach to both flat- and spherical-head tripods, and the standard optical sight lens helps you find your target quickly, easily and accurately. And a mirror with a pentaprism lets you view the circular bubble as an erect image during setup and sighting. You can also choose a plane parallel micrometer for high-precision leveling, a cross-hair illuminator for working in tunnels, or a diagonal eyepiece prism for steep sighting.
