1. Introduction
The Nohawk NK-1000 Hunting Laser Rangefinder is a high-precision optical instrument designed for accurate distance measurement. It is suitable for a variety of applications including hunting, golf, outdoor sports, and construction surveying. This manual will guide you through the setup, operation, and maintenance of your device.

2. Setup
2.1 Unboxing
Upon opening the package, ensure all components are present. The package typically includes the rangefinder unit, a protective case, and a charging cable.
2.2 Charging the Device
The Nohawk NK-1000 features a built-in rechargeable lithium battery. To charge the device, connect the provided USB-C cable to the charging port on the rangefinder and to a suitable USB power source.

3. Operating Instructions
3.1 Device Overview
Familiarize yourself with the main components and controls of the rangefinder:
- Eyepiece: Used for viewing the target and display. Features adjustable focus.
- Mode Button (M): Used to switch between different measurement modes (e.g., Meter/Yard).
- Measurement/Scanning Button: Used to initiate a measurement or continuous scanning.
- USB-C Charging Port: For recharging the internal battery.

3.2 General Operation
- Power On: Press the Measurement/Scanning button to turn on the device.
- Adjust Focus: Rotate the eyepiece to adjust the focus until the display and target are clear.
- Select Mode: Press the Mode (M) button to cycle through the available measurement modes (e.g., Range, Scan, Speed, Bow, Two-Point Altimetry, Golf Slope Compensation).
- Measure: Aim the crosshairs at your target and press the Measurement/Scanning button. The measured distance and other relevant data will appear on the display. For continuous scanning, press and hold the Measurement/Scanning button.
- Unit Switching: Use the Mode (M) button to switch between meters (M) and yards (Y) if applicable.


4. Measurement Modes
The NK-1000 offers several specialized measurement modes to enhance your experience:
- Linear Distance Measurement: Measures the direct line-of-sight distance to a target.
- Speed Measurement: Calculates the speed of a moving target.
- Scanning Mode: Allows continuous measurement of multiple targets or a moving target by pressing and holding the measurement button. Useful for tracking distances to obstacles or moving game.
- Horizontal Distance: Provides the horizontal distance to the target.
- Vertical Distance: Measures the vertical distance to the target.
- Angle Measurement: Displays the angle of inclination or declination to the target.
- Two-point Height Measurement: Measures the height difference between two points.
- Golf Mode / Slope Compensation / Flag Pole Locking: Specifically designed for golf, this mode provides slope-adjusted distances and can lock onto the flagstick.
- Memory Storage Function: Stores previous measurements for quick recall.

4.1 Range Mode and Scan Mode
Range Mode: Measure the direct distance to a stationary target.
Scan Mode: For moving targets or continuous measurement, press and hold the measurement button to get real-time distance updates as you pan across an area or track an object.

4.2 Speed Mode and Bow Mode
Speed Mode: Aim at a moving target to calculate its speed. The display will show 'SP' along with the speed data.
Bow Mode (HD): Primarily used to measure the true horizontal distance from your position to the target object, compensating for vertical angles.

4.3 Two Point Altimetry Mode
This mode allows you to measure the difference in height between two distinct points. Aim at the top point, then the bottom point, and the device will calculate the vertical distance (H).

4.4 Golf Slope Compensation
In Golf Mode, the rangefinder provides slope-compensated distances, which is crucial for accurate club selection on sloped terrain. It accounts for elevation changes, giving you the 'plays like' distance.
