3. Product Features

The Mileseey PF3S Laser Rangefinder offers a range of advanced features for accurate and versatile measurements:

• **External Display Screen**: Data can be shown by an external display screen during measuring, making it more efficient for co-workers to read measuring data.
• **Golf Trajectory Compensation (Slope Adjusted Measurement)**: Quickly calculates the distance and angle for ballistic compensation, providing accurate data for golf players, especially in concave or hillside terrains.
• **Point-to-Point Measurement**: Uses 3D locating technique to measure any distance from one point to another.
• **Angle Switch Design**: Allows for switching between different measurement modes and turning off angle sensor for distance-only measurements.
• **Flagpole Lock Function**: Priority for close range mode, positions and locks the close target when measuring small targets at a long distance.
• **Speed Measurement Mode**: Measures the velocity of movement, useful for watching motor racing or hunting.
• **TOF (Time of Flight) Measuring Technique**: Ensures faster measurement speed and longer measuring range, suitable for outdoor far-range measurement.
• **Environmentally Friendly Material**: Device body is made of non-toxic, soft rubber for comfortable hand holding, anti-skid, and wear-resistance.
• **6X Fixed Focal Length Ranging System**: 7° perspective and coated lens make the target more clear and bright.

5.2. Initial Power On

Press the **Power / Measure button** once to turn on the device. The display will light up.

6. Operating Instructions

6.1. Adjusting Focus

Rotate the **Eyepiece knob** until the display and target appear clear and sharp.

6.2. Switching Measurement Units (Meters/Yards)

With the device powered on, short press the **Mode / Unit switch button** to cycle through available measurement units (meters or yards).

6.3. Measurement Modes

The PF3S offers 7 measurement modes. Short press the **Mode / Unit switch button** to cycle through them.

6.3.1. Point-to-Point Ranging Mode

1. Short press the **Mode / Unit switch button** until the point-to-point icon appears.
2. Aim at target A, press the **Power / Measure button**.
3. Aim at target B, press the **Power / Measure button**. The measured distance between A and B will be displayed.
4. Move to target C, press the **Power / Measure button**. The measured distance between A and C will be displayed. The distance and angle between B and C will also be calculated and displayed.

Note: Stand still while measuring the target.

6.3.2. Golf Slope Adjusted Mode

This mode provides trajectory compensation for golf. If you are in a concave or hillside area, select this mode, target the flag, and press the measure key to get the actual distance.

1. Short press the **Mode / Unit switch button** until the golf slope adjusted icon appears.
2. Aim at target B (e.g., flagpole) and short press the **Power / Measure button**.
3. The measured distance between A and B, and the slope adjusted distance and angle will be displayed.

Slope adjusted angle/Slope range: -20° to +20°.

6.3.3. Golf Scanning Mode

1. Short press the **Mode / Unit switch button** until the golf scanning icon appears.
2. Aim at target B, short press the **Power / Measure button** (flag icon is flashing).
3. Scan slowly back and forth on both sides of the measured target. After 1.5 seconds, the flagpole stops flashing, and the data shows the measured distance between A and B, slope adjusted distance, and angle.

6.3.4. Distance, Height, Angle Measurement

1. Short press the **Mode / Unit switch button** to activate this mode.
2. Aim at target B, press the **Power / Measure button** to get the measured distance between A and B, height, distance, and angle between B and C.

6.3.5. Vertical Height (between two points)

1. Short press the **Mode / Unit switch button** to activate vertical height measuring mode.
2. Aim at target B, press the **Power / Measure button** to get the distance and angle (angle between the measured distance and horizontal surfaces) between A and B.
3. Move to target C, press the **Power / Measure button** to get the distance and angle between the measured distance and horizontal surface) between A and C. The vertical height between B and C will be displayed on the top, and the absolute value of the difference between the two angles will be displayed at the bottom.

6.3.6. Speed Measuring Mode

1. Short press the **Mode / Unit switch button** to activate the speed measuring mode.
2. Aim at target B and move slightly. The speed of the movement can be measured accordingly.

Note: The angle 'α' must be less than 10°. The smaller the angle, the higher the accuracy.

10. User Tips

• **Clarity of View**: To ensure the clearest view, always keep the objective lens and eyepiece clean. Use a soft, lint-free cloth specifically designed for optics. If the view seems less clear than expected, check for smudges or dust on the lenses.
• **Steady Aim**: For the most accurate measurements, especially at longer distances or when using advanced modes, ensure you hold the rangefinder as steadily as possible. Using a tripod (via the tripod screw hole) can significantly improve accuracy.
• **Environmental Awareness**: While the rangefinder is designed for outdoor use, extreme conditions like heavy fog or rain can affect laser performance and accuracy. For best results, use in clear conditions.
