This CRL Zircon"® Electronic Water Level is based on the basic principle of water leveling. It is very easy to use; and can be set up in seconds and operated by one person. Simply affix the Level to a preset leveling point and raise the free end of the hose at the place where you want to find level. When the top of the water column in the free end is on the same plane as the preset leveling point, a loud signal indicates that you have found level.
Over a distance of inches, or up to 200 feet (using accessory hoses), the CRL Zirconº Level makes the grade for erecting fences and decks, positioning drainage and plumbing, completing masonry work and remodeling interiors. For the professional or home craftsman, it is the only leveling device that works around "blind" corners.
This CRL Zirconº Electronic Water Level includes 25 feet of hose, an adaptor and carrying case. It requires a nine volt battery (not included).
