Spike is a laser measurement solution that allows you to measure an object simply by taking a photo with your smartphone or tablet. From that photo, you can capture real-time measurements including areas, elevations, distances between two points, and GPS/GNSS location. The Spike laser device, Spike mobile app, Spike Cloud and your smartphone or tablet work together to bring measurements within reach. When Spike is paired with the Bad Elf GPS receiver, the GPS accuracy of the mobile device is significantly improved delivering a simple, affordable measurement and mapping workflow.
