Zircon has updated the industry's traditional water levels with modern electronics to ensure a new grade of accuracy. The Zircon WL 25 Pro Electronic Water Level Contractor Kit makes larger leveling projects a piece of cake for determining level reference points up to 50 feet (15 m) away. Additional hoses can also be purchased separately and can be expanded up to 100 feet. This professional Zircon Water Level Contractor Kit simplifies not only working alone but also works around corners with accurate and reliable measurements. The WL 25 Pro is great for a number of applications, including erecting fences, building decks and patios, positioning drainage, plumbing, setting forms, completing masonry work, and remodeling interiors. This water level includes a battery saving indicator that continuously blinks and beeps to remind the user that the unit has been left on. Unlike other electronic water levels, the WL 25 Pro can be used both indoor and outdoor with its easily read display, even in bright lighting situations both indoor and outdoor. The key for optimal performance? Be sure to install a new 9V battery with an extended expiration date. The WL 25 includes the leveling unit, a mounting bracket, clamp, hose brush, two hose connectors, garden hose connector, filler nozzle and two 25-foot (7.5 m each) hoses for a total of 50 ft. With the Zircon WL 25 Pro Contractor Kit, you can safely maneuver through even your most difficult project with the professional confidence that comes from owning a Zircon.
