Laser Measure - Holiday Gift Guide for Gadget-Loving DIYers - Bob Vila
Zircon Sonic/Laser Measure DM S50L
It's fun to shoot lasers—which is why when we were kids, our holiday gift lists used to include Star Trek–style toy guns—but digital laser measures are a lot more practical. This one uses a laser to target the spot you want to measure, then bounces sonic waves off it to give an accurate distance. Let’s see Spock’s tricorder do that! It also automatically calculates area and volume and works in U.S. or metric measurements. Available on Amazon; $45.
