Compass Card

The compass card is another critical component of the Raytheon Anschutz bearing sight. It displays the ship's heading, allowing the navigator to determine the bearing of the target object relative to the vessel. The compass card is typically graduated in degrees, with markings for cardinal and intercardinal directions. The card is designed to be highly accurate and stable, providing reliable heading information even in rough seas. Some advanced models may incorporate electronic compasses that provide digital heading readouts, further enhancing accuracy and ease of use. Proper calibration of the compass card is essential to ensure that the bearing sight provides accurate navigational data.

Sighting Mechanism

The sighting mechanism is what you use to align the bearing sight with the target object. It usually consists of a set of crosshairs or a similar aiming device that allows the navigator to precisely pinpoint the object's location. The sighting mechanism is designed to be adjustable, allowing the user to compensate for parallax and other sources of error. Some models may also include a built-in rangefinder, which can be used to estimate the distance to the target object. The sighting mechanism must be robust and stable to ensure that the bearing sight provides accurate readings, even when the ship is moving. Regular inspection and maintenance of the sighting mechanism are essential to prevent wear and tear.

Housing and Mounting

The housing and mounting are the physical structures that support and protect the other components of the bearing sight. The housing is typically made from durable materials such as brass or aluminum, which are resistant to corrosion and can withstand the harsh marine environment. The mounting is designed to securely attach the bearing sight to the ship's structure, providing a stable platform for taking bearings. The mounting may also include features such as vibration damping, which helps to minimize the effects of ship motion on the accuracy of the readings. Proper installation and maintenance of the housing and mounting are essential to ensure that the bearing sight remains in good working condition.

How to Use a Raytheon Anschutz Bearing Sight

Using a Raytheon Anschutz bearing sight might seem complex at first, but with a bit of practice, it becomes second nature. Here’s a step-by-step guide to help you get started:

1. Preparation: Before you begin, make sure your bearing sight is clean and properly mounted. Check that all components are functioning correctly and that the compass card is accurately calibrated. This ensures that your readings will be as accurate as possible.
2. Locate the Target: Identify the object you want to take a bearing on. This could be another ship, a landmark, or any other navigational aid. Make sure you have a clear view of the target and that it is easily distinguishable from its surroundings.
3. Align the Sight: Use the sighting mechanism to align the bearing sight with the target object. Look through the optics and adjust the crosshairs or aiming device until they are precisely aligned with the object. Take your time and make sure the alignment is as accurate as possible.
4. Read the Bearing: Once the sight is aligned, read the bearing from the compass card. This will give you the direction of the target object relative to the ship's heading. Record the bearing carefully, noting the time and any other relevant information.
5. Correct for Errors: Depending on the situation, you may need to correct for various sources of error, such as magnetic variation and deviation. Consult your charts and navigational publications to determine the appropriate corrections. Apply these corrections to the bearing to obtain a true bearing.
6. Plot the Bearing: Use the corrected bearing to plot a line of position (LOP) on your chart. This LOP represents all possible locations of the ship along that bearing. By plotting multiple LOPs from different objects, you can determine your ship's position with a high degree of accuracy.
7. Verify the Results: After plotting your position, verify the results by comparing them with other navigational information, such as GPS data or radar fixes. If there are any discrepancies, investigate the cause and take corrective action.
