A rangefinder measures length or distance, and can integrate angle-measuring tools to calculate parameters like angle and area. Electronic rangefinders cost 500–5000 yuan, with prices rising as required functions and accuracy increase. Choose one by focusing on three key factors: measurement range, distance, and usage scenario.
Key Breakthroughs
1. Small Measurement Range (Indoor Use)
For distances of a few meters to a dozen meters and low accuracy needs, an ultrasonic rangefinder is ideal. Though its stability and directionality are worse than laser types (and easily affected by the environment), it is more affordable.
2. Short Measurement Distance (Indoor Priority)
If the distance is short, ambient light is simple, and millimeter-level accuracy is needed, opt for a phase laser rangefinder. It works best indoors, with an accuracy of under 2mm. For outdoor use, pair it with professional laser sights and reflectors to meet expected range and effect.
3. Medium-Long Distance (Outdoor Use)
Choose a telescope-type laser rangefinder (or laser rangefinder telescope). It doubles as a telescope—with multiple magnifications for observation—and uses a built-in cross aiming system in the eyepiece for easy targeting. It emits eye-safe transparent infrared laser for accurate measurement, and is compact, lightweight, and portable.
4. Long-Distance (Outdoor Use)
Prioritize a rangefinder with a built-in telescope, which ensures clear visibility even in strong light for precise measurements.
