TAPE/LASER MEASUREMENTS: The Digital Tape Measure with Laser smoothly switches between tape and laser measurement modes for both close and long distance measurements. The advanced laser mode has a range of up to 196ft, which greatly extends the limits of the tape measure and ensures that it can be used in any measurement scenario. LASER GUIDE - An integrated, fine width, green laser projects and extends across from the reference extending the ability to align and mark. The green laser line provides crystal-clear visual guides for alignment and marking. AUTOMATIC CALCULATIONS: In addition to measuring individual lengths, the digital tape measure automatically calculates area, volume, indirect horizontal distance, and height, eliminating the need to write down each length for manual calculations and improving measurement efficiency and accuracy for complex tasks. MEASURING LIST: The electronic display shows previously saved measurements (up to 100), which can be viewed, organized and deleted as needed so you never forget a measurement. INNOVATIVE FUNCTIONS: Incremental measurements requires no math operations as the digital laser tape measure allows for the data at any point. Internal measurement has never been made easier by using the rear reference. Switch between m, in, ft, ft/in as needed.
