【November 20, 2025, Chengdu】 – Today, SunFlaser Technology (Chengdu) Co., Ltd. officially unveils its new generation “1064 Handheld Rangefinder” series. To begin with, the series is available in six range specifications: 6 km, 8 km, 10 km, 12 km, 20 km, and 25 km. As a result, it delivers high‑precision, lightweight laser ranging solutions for surveying, power line inspection, emergency rescue, outdoor sports, and more.
1064nm Laser Technology Upgraded
To begin with, the new products continue to leverage the company’s proven 1064nm wavelength laser platform. Specifically, they offer stronger penetration and significantly improved anti‑interference capability compared to conventional 905nm solutions. Furthermore, we pair them with our self‑developed fourth‑generation ToF (Time‑of‑Flight) algorithm. Consequently, single‑point measurement accuracy is stable at ±0.3 m (for distances <1 km) and ±0.5 m (full range). Additionally, the system can capture large reflective targets at up to 25 km. As a result, this sets a new benchmark for handheld rangefinder range performance.
I. Features
- To begin with, we equip the series with an Nd:YAG laser at 1064nm wavelength.
- Furthermore, effective ranging reaches up to 20 km and 25 km respectively, with accuracy of ±1 m.
- Additionally, the system supports long‑range measurement without requiring cooperative targets.
- Moreover, it offers digitally selectable range gating with arbitrary adjustment.
- For night‑time aiming, we include illuminated reticle crosshairs.
- The device measures straight‑line distance, angle, horizontal distance, and vertical distance.
- We also offer an optional electronic compass for azimuth and span measurement.
- A single laser pulse can measure two targets simultaneously.
- The system provides 81 target data storage and recall.
- It also features laser shot count logging.
- For data transfer, we include an RS232 data interface.
- The construction features all‑metal, waterproof and vibration‑resistant design.
- Operating temperature ranges from -40°C to +60°C.
II. Key Technical Specifications
- 6 km / 8 km models: To begin with, these weigh only 480 g, making them ideal for lightweight scenarios such as surveying, golf, and hunting. Additionally, they deliver up to 3000 measurements per charge.
- 10 km / 12 km models: Furthermore, these add continuous ranging and area/volume calculation – thereby doubling efficiency for power line inspection and waterway surveying.
- 20 km / 25 km models: Finally, these feature a built‑in 3‑axis tilt sensor, supporting one‑button calculation of spatial span, horizontal distance, and height difference between two points. Consequently, they meet long‑range demands in emergency rescue and railway line‑of‑sight surveying.
Military‑Grade Reliability, Civilian‑Friendly Usability
To begin with, the entire unit features a magnesium‑alloy housing with a drop height resistance of 1.2 m and IP67 protection. Furthermore, the OLED semi‑transparent display remains clearly readable even at -30°C. Additionally, Type‑C fast charging provides up to 3000 measurements in just 5 minutes. Moreover, the menu is available in Chinese and English, with near‑zero learning curve.
Open SDK – Building an Ecosystem
Furthermore, SunFlaser simultaneously releases a mobile SDK and Windows desktop drivers. As a result, these enable secondary development of coordinate transformation, AR annotation, IoT cloud data upload, and more. Consequently, this helps integrators quickly deploy systems such as UAV pods, unmanned surface vessel depth sounding, and online monitoring.
Pre‑Order & Availability
To conclude, the 1064 Handheld Rangefinder series is now open for global pre‑orders. Furthermore, mass production units are expected to ship by mid‑December, backed by a 3‑year warranty on the main unit and a 5‑year warranty on the laser.
