Product Introduction

LM600G series laser rangefinders can be used in power equipment installation, highway, municipal engineering, forestry survey and design, construction, network planning, communication maintenance, and golf.

• While clearly observing objects, the product can measure the distance of fixed or slow-moving objects in a certain range. It has the advantages of high accuracy, short measuring time, direct distance display, low power consumption, and auto power off.
• The laser power is small. The product can measure any target. It is compact and portable and has a built-in rechargeable lithium battery.

Features:

• Compact and portable;
• High precision and speed, low power consumption;
• Multi-function LCD;
• Harmless class, I pulse laser;
• Mute operation and auto power off;
• Built-in 750mAh rechargeable lithium battery;
• Flagpole lock mode to measure slender targets;
• Golf trajectory compensation mode to calculate the actual shot distance;
• Height and horizontal mode apply to engineering surveying.

Power On

Rotary Focusing Ring
According to the positive and negative indications on the knob as a reference.

Users who can’t see close (e.g., farsighted) should rotate in the “+” direction, and users who can’t see far (e.g., nearsighted) should rotate in the “-” direction. Rotate the knob to match eye distance with pupil distance.

Modes
Short press  switch between different modes.

There are 5 modes:

1. Linear distance mode: Measure the linear distance between the user and the target.
2. Flagpole lock mode: Lock the nearest target distance.
3. Golf trajectory compensation mode: Measure the golf trajectory compensation distance.
4. Height and horizontal mode: Measure the relative height and horizontal distance between the user and the target.
5. Speed measurement mode: Measure the target speed.

Units and Vibration
Long press for 2s to enter the setting interface.

• Units
  Short press to switch between m and Y.
  Short press to set the vibration mode.
• Vibration
  Short press to turn on/off the vibration mode.
  Short press to complete the setting

Note:

1. If the vibration mode is turned on, the product will vibrate once when measuring distance, and twice when locking the flagpole.
2. If the vibration mode is turned off, the product will not vibrate when measuring distance, and twice when locking the flagpole.

Linear Distance
Measure the target distance, height, and angle.
Single measurement: Short press  to take a measurement.
Continuous measurement: Long press to scan the laser across an area and get continuously updated range readings.

Flagpole Lock
When measuring overlapping targets, long press to display the distance of the nearest target. For example, if it is not clear whether the measured target is the flag or the forest behind it, the product with the flagpole lock function will lock on the nearest target, the flagpole.

Golf Measurement
Long press to display the golf trajectory compensation distance, height, and actual distance.

Uphill	Downhill

Height and Horizontal Distance
Short/long press to display the relative height and horizontal distance of the observer to the target.

Speed Measurement
Press and hold and aim at the moving target. The product will calculate the target speed in real-time and display it on the LCD.

Cautions

• The product emits an invisible and harmless infrared pulse laser which is then reflected back to the optical receiver on the product from the target. By measuring how long it takes each pulse laser to travel from the rangefinder to the target and back, the product system uses a precise charging circuit to calculate the measured distance in real-time. The maximum measurement range of the product depends on the target’s reflectivity, color, surface finish, size, and actual shape.

The following factors can ensure optimal range and accuracy:

• Sunny weather
• No impurities in the air
• Bright color targets
• Targets with a bright appearance
• Targets with high reflective surfaces

The following factors cannot ensure optimal range and accuracy:

• Black targets
• Small or micro targets
• Strong light/sunlight
• Snow, rain, or fog
• Targets with diffuse surfaces.
• Targets to be measured through the glass.
• Moving targets
• When the battery status is , please charge the battery immediately.
• Do not touch the lens surface to protect the film layer.
• Do not disassemble the product. If it is damaged, send it to specialized departments for maintenance.
• Please wipe the lens gently with a cleaning cloth. Do not wipe with other objects.
• Avoid collision or heavy pressure when carrying.
• Do not bake or corrode the product.
• Store the product in a dry, cool, and ventilated place, away from direct sunlight, dust, and sudden temperature changes.
• Do not direct the product to the sun or a strong light source.
