The GoTo Rangefinder uses a 905 nanometer laser that meets the standard of Class 1 and is safe for human eyes. It emits energy pulses and its microprocessor determines slope distance, horizontal distance and vertical height by calculating how much time it takes for each pulse to travel from the GoTo Rangefinder to the target and from the target back to the GoTo Rangefinder.
The GoTo Rangefinder displays measurement in seven (7) different modes. The last mode in use will be displayed when the GoTo Rangefinder is turned on. Press the Mode Button to change modes. The modes will change in the following sequence.
Measures the difference in elevation from the GoTo Rangefinder to a target.
Measures the horizontal distance (the distance to a point above or below a target) as the GoTo Rangefinder scans an area.
Measures the height difference between two targets.
Measures the distance of the closest target among various targets.
Measures the distance of the farthest target among various targets.
Calculates the recommended throwing distance after accounting for elevation.
Stores your most recent 20 slope distance readings with the most recent measurement (01) displayed first.
After taking a measurement with the GoTo Rangefinder at a horizontal plane, the angle value should display as 0° if the GoTo Rangefinder is properly calibrated.
