AOFAR HX-1100V Hunting Rangefinder

Product Overview

The AOFAR HX-1100V is a laser rangefinder designed for hunting and outdoor activities. It provides accurate distance measurements, angle readings, and speed measurements.

Brand: AOFAR

Model: HX-1100V

Manufacturer: CHANGZHOU JIANFU OPTOELECTRONIC INSTRUMENT CO.,LTD.

Operation Instructions

Focus Adjustment

The HX-1100V features an adjustable eyepiece with a +/-3 Diopter range, allowing users with different vision prescriptions to observe the LCD clearly without glasses. Rotate the eyepiece until the reticle and object display are sharp.

Modes Memory Function

The rangefinder defaults to RANGE mode upon startup. Any operational settings or modes selected will be remembered and applied on the next power-on after shutdown.

Functions of "MODE" Button

Units Switch

The unit of measure (Yards or Meters) is indicated in the lower right portion of the LCD. To switch between Yards (Y) and Meters (M), press and hold the "MODE" button for 3 seconds.

Mode Switch

Single-point the "MODE" button to cycle through the available modes: Range mode, Speed mode, and Scan mode.

Range Mode

Display: The display shows an aiming circle, distance, angle, and unit indicator (Y/M).

Operation: Aim the center circle at a target more than 5 yards away. Press and release the "POWER" button. The rangefinder will display the range and angle, followed by the horizontal distance. The device automatically powers off after 8 seconds of inactivity.

The upper part of the LCD shows the angle of the target (uphill/downhill), which is then converted to the horizontal distance.

Speed Mode

Display: The "Spd" logo appears on the left side of the screen, along with the speed unit (e.g., m/s).

Operation: Single-click the "POWER" button to aim at a moving target (target B) and track its movement. The speed of the target is displayed. Ensure the aiming circle is aligned with the target until it stops flashing. For accurate speed measurements, the angle of elevation (α) should be less than 10 degrees.

Diagram shows a person aiming at a target B on a slope, with an angle α indicated.

Scan Mode (Continuous Scan)

Display: The "Scan" logo appears on the left side of the screen.

Operation: Press and hold the "POWER" button to continuously scan and measure distances to multiple targets. The "scan" indicator remains active. The center circle flashes during scanning. The angle and distance readings update dynamically. The final readings for the last target are displayed upon completion. This mode is recommended for measuring targets in challenging hunting conditions.

Hunting Mode Instruction

This mode is particularly useful for bowhunters who rely on accurate horizontal distance. For example, if the straight-line distance to a deer is 32 yards with a -44 degree angle, the true horizontal distance is 23 yards. Shooting at 32 yards would cause the arrow to go over the target. Bowhunters need the horizontal distance for precise aiming adjustments. The perceived difference in uphill/downhill shots is often due to the bow's sighting system rather than gravity.

Diagram illustrates a deer on a slope, showing line of sight (32 yards), angle (-44°), and true distance (23 yards).

How to Work and Ranging Accuracy

The HX-1100V emits invisible, eye-safe, infrared energy pulses. Sophisticated digital technology calculates distances by measuring the time it takes for each pulse to travel to the target and back. The accuracy of the measurement can be affected by the target's color, surface smoothness, size, and sharpness, as these factors influence reflectivity.

Measurement can be difficult under the following conditions:

• Raining or fogging
• Target is too small
• Low reflectivity of the measured object (e.g., black surfaces, complex shapes, curved surfaces, water, glass, or mirror surfaces)
• Low battery power

Components Name

The rangefinder has the following components:

1. Laser Transmitting Objective Lens
2. Laser Receiving Objective Lens
3. Units Switching Button / "M" button (m: Meter / Y: Yard)
4. Power/Reading Button
5. Rotary Focusing
6. Battery Cap

Getting Started (Inserting the Battery)

1. Remove the battery cap by rotating it counter-clockwise.
2. Insert a CR2-3V battery, ensuring the negative pole [-] is placed into the battery compartment first.
3. Replace the battery cap by tightening it clockwise.

Note: It is recommended to replace the battery once every 12 months.

Low Battery Indicator: If the low battery symbol [low battery symbol] appears on the LCD, the 3-volt lithium battery should be replaced.

Safety Instructions

• Prevent the instrument from falling or getting damaged. Do not tamper with it. Contact customer service for any abnormal noise.
• Operating temperature range: -10°C to 50°C. Use or store the instrument within this range and avoid environments with sharp temperature changes.
• Do not expose the product to direct sunlight, high temperatures, or low temperatures for extended periods (e.g., in a car trunk).
• Do not expose your eyes to the laser beam or aim it at the sun.
• Do not use or store the product in environments with strong electromagnetic radiation or magnetic fields.
• If the product will not be used for a long time, remove the battery and store it in a cool, dry place, preferably in a dry box.
• Do not disassemble, modify, or repair the product yourself. Doing so may cause damage to the instrument or harm from laser irradiation.
• Avoid using the device in dusty areas to prevent failures.
• While the product has a waterproof function, do not intentionally get it wet or immerse it in water. If moisture is present around the buttons, wipe it dry before operation.
• Always ensure the battery cover is securely closed when using the device.

Warnings and Precautions

Warning!

• Do not look directly at the Laser Transmitting Objective Lens [1].
• Do not measure the eyes of others.
• It is forbidden to detach this product yourself.
• Keep the product out of reach of children.

Attention!

• It is normal for the lens to fog up when temperature changes suddenly. In such cases, remove the battery and do not use the device until it is dry.
• Moving the device from a cold environment to a warm one may cause condensation (dew) on the appearance and internal parts. To prevent this, place the device in a waterproof plastic bag and allow its temperature to gradually increase before removing it.
• To avoid failures, do not store the product in:
  1. Unventilated and humid places
  2. Cars or trunks exposed to the sun
  3. Environments with humidity over 90%
• Do not preserve or place the lens under the sun, as its radiation convergence function can harm the LCD.

Precautions for Lithium Battery

• To prevent leakage, heat, and fire, do not disassemble or modify the product.
• Do not throw the battery into fire or store it in high temperatures.
• Avoid direct contact of the battery with metal objects such as coins or keys.
• If skin comes into contact with leaked liquid, rinse immediately with cool water. If the liquid contacts eyes or mouth, do not rub; rinse with cool water and consult a doctor.
• Keep batteries out of reach of children.
• Dispose of used lithium batteries according to your local regulations and native policies.

Maintenance of the Instrument

Gently wipe the lens surface with a clean, soft cloth to remove any stains that could cause damage. Avoid touching the lens with your fingers to protect its coating.

Trouble Shooting Table

If LCD Can't Be Turned On:

• Press the Power button again.
• Check or replace the battery. Ensure there is no insulator blocking the battery power.

• Confirm whether the lens has dirt.
• Ensure the aiming circle overlaps your target.

If Device Turns On, But Data is Not Displayed:

• Low battery voltage: Please change the battery.
• Target is out of measurement range or less than 5 yards.
• Change the measurement target.

Measurement Error:

• Ensure the M/Y unit switch is set correctly.
• Rain, fog, or small targets can affect measurement results.

Battery Power Runs Out Quickly:

• Low ambient temperature can cause rapid battery drain.
• If the battery has not been used for a long time after unpacking, its power may deplete quickly.
