•The continuous measurement finds distance from target quickly and easily, and makes indirect measurement using pythagoras. It measures height even when point A and/or point B is not accessible for linear measurement. This unit stores the last 5 measurements taken for reference, and features a backlit 2-line display, which provides visibility in all working conditions. •The corner stand-off end post makes true corner-to-corner measurements easy and accurate, and over-moulded housing makes this IP54 water and debris resistant for durability and added protection. •Supplied complete with batteries and protective pouch.
