ZipLevel Pro-2000 Level

Unlike a rotary laser, ZIPLEVEL lets you truly work alone to quickly and easily level and read elevations directly in unmistakably clear digits. NO MORE rods, tripods, sensors, line-of-sight, error with distance, factory calibration and tedious computations. Now you can measure over any distance or elevation on earth, from paper thickness to the height of a mountain without error-inducing tabulation and math.
