4,000 m Ultra-Long Range Measurement Capability
Measure targets from 10 meters up to 4,000 meters with stable accuracy, allowing operators to capture reliable distance data across mountains, valleys, construction sites, and large-scale outdoor environments without physically approaching the target area.
Integrated Distance, Height & Two-Point Measurement System
Combine three essential field measurement functions in one device—direct distance, vertical height, and inter-point span calculation—enabling users to complete complex surveying and structural assessment tasks without carrying multiple instruments or performing manual trigonometric calculations.
High-Speed Laser Processing for Instant Field Data
Deliver measurement results in as fast as 0.5 seconds, providing near real-time distance feedback that improves decision speed in time-sensitive operations such as surveying, inspection, and tactical observation.
Lightweight 223 g Compact Monocular Design
Engineered at only 223 g with a pocket-sized body, the SAM5 significantly reduces operator fatigue during long field missions while remaining easy to carry, deploy, and operate with one hand in dynamic working conditions.
Single-Handed Ergonomic Operation Interface
Optimized button layout allows full measurement control without changing grip or removing the eye from the target, ensuring faster target acquisition and uninterrupted workflow in fast-paced outdoor or tactical environments.
7× Optical Magnification with Real-Time Data Overlay
A high-quality monocular optical system provides clear target visibility while simultaneously displaying measurement data in the same viewing path, enabling users to observe and measure in one continuous action without switching devices.
High-Precision Distance Output with Field Reliability
Designed to maintain consistent measurement accuracy in outdoor conditions, supporting dependable distance and height data collection across reflective, natural, and uneven terrain targets where conventional tools often lose reliability.
Rugged Outdoor-Ready Construction
Built with a durable housing structure that withstands dust, moisture, and impact exposure, ensuring stable performance in harsh field environments such as forestry, construction sites, coastal zones, and remote terrain operations.

Frequently Asked Questions
A laser rangefinder combines traditional monocular / binocular observation with an integrated laser distance measurement system, allowing users to observe and measure targets using a single device.
The SAM5 is both. It combines a laser rangefinder with a 7× monocular optical system, allowing users to observe and measure targets through a single device.
Yes. The built-in height measurement mode enables users to calculate the height of trees, towers, buildings, cliffs, and other vertical structures without physical access.
Two-point measurement calculates the straight-line distance between two remote targets. This is useful for measuring river widths, tower spacing, clearance distances, and infrastructure spans.
