Spectra Precision AL28M Automatic Level 28 power

Product Description

Spectra Precision AL28M Automatic Level 28 power Magnetically Dampened
Easy-to-Use Optical Level

The AL28M series automatic levels are designed for a variety of elevation control and alignment tasks including general building construction, cut and fill measurements, area leveling, and landscaping.

Reliable automatic compensators ensure stability and accuracy in the line of sight. Telescope optics are bright and clear providing sharp images for ease of viewing. A short focusing distance provides for better performance in tight spots or on steep slopes. Stadia lines on the reticle make distance calculations easy. A horizontal scale directly below the eyepiece makes angle measurement quick and convenient.
