6. Operating Modes
The REVASRI Laser Rangefinder offers multiple measurement modes to suit various applications. Press the Mode Button to cycle through the available modes.
Image: Visual representation of the seven measurement modes: Single Ranging, All-in-one, Scan, Two Point Height, Speed Measurement, Golf, and Memory Storage.
6.1 Single Ranging Mode
This is the standard mode for measuring the direct line-of-sight distance to a single target. Press the Action/On Button once to power on, then aim at the target and press the Action/On Button again to get the distance.
6.2 Scanning Measurement Mode
For continuous measurement of multiple targets or moving objects. Press and hold the Action/On Button while sweeping across different targets. The display will continuously update with new distance readings.

6.3 Golf Mode with Flag Lock
Designed for golf, this mode allows you to easily lock onto the flagstick, even with trees or other objects in the background. Scan the area around the flag, and the device will identify and lock onto the closest target, typically the flag.
6.4 Two Points Height Measurement Mode
Measures the height difference between two points. Aim at the base of the object, take a reading, then aim at the top of the object and take another reading. The device will calculate the height.
6.5 All-in-one Mode
This comprehensive mode displays multiple measurements simultaneously: angle, height, horizontal distance, and straight-line distance to the target. This is particularly useful for hunting and complex terrain.

6.6 Speed Measurement Mode
Measures the speed of objects moving in the radial direction (towards or away from the rangefinder). The unit of measurement for speed is KM/H.
6.7 Storage Mode
Allows for saving and recalling previous measurement data. Refer to the on-screen prompts for specific instructions on saving and accessing stored readings.
7. Maintenance
- Cleaning Lenses: Use the provided lens cleaning cloth or a soft, lint-free cloth to gently wipe the objective and eyepiece lenses. Do not use abrasive materials or harsh chemicals.
- Cleaning Body: Wipe the body of the rangefinder with a soft, damp cloth. Avoid excessive moisture.
- Storage: When not in use, store the rangefinder in its protective case in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery: Remove the battery if the device will not be used for an extended period to prevent leakage.
- Water Resistance: The device is water-resistant (IP54 rated), meaning it can withstand splashes and light rain. Do not submerge the device in water.
8. Troubleshooting
If you encounter issues with your rangefinder, refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Cannot get a reading / No display. |
|
| Reading seems inaccurate. |
|
| Black numbers hard to see in viewfinder. | This can occur against dark backgrounds. Try to find a contrasting background or adjust your viewing angle if possible. The display is an in-view LCD. |
| Device blinks on/off. | Check battery connection and charge. Ensure the battery compartment cover is secure. If the issue persists, contact customer support. |
