It's almost an insult to even call this powerful measurement tool a "Laser Rangefinder" because its capabilities go far beyond just measuring a range. You can instantly measure slope distance, inclination and azimuth* and calculate horizontal and vertical distance - all with a single push of a button. The 360 laser rangefinder has an integrated compass that allows you to measure azimuth and provides an extra onboard solution called missing line. This is a simple 2-shot routine that instantly calculates the distance, inclination and azimuth direction value between any two remote points. The 360 R laser rangefinder is the latest in the TruPulse Series offering all of the same functionality as the 360 B, but with the added benefit of being rugged and waterproof. Now professionals have the opportunity to work out in the field knowing their equipment is protected for harsher weather conditions.
