PREXISO portable measuring device is indispensable for various construction tasks. It combines multiple measuring functions: a standard 16-foot tape measure and a laser with a maximum working distance of 135 feet. It also features a small display that shows all measurement information. The device can perform calculations based on built-in formulas. The laser measurement system offers six modes. The shock-resistant, rubberized housing has a magnetic hook that attaches to metal surfaces. The tape measure operates on a battery — with a full charge, up to 5000 measurements can be made. It charges via a USB cable.
