First you read the compass. Then you find the correction for the heading closest to the heading the compass reads, interpolating if needed. Then you add the correction to the heading to get the corrected heading.
For example, say the compass read 37 degrees and the correction card had a +2 correction for 30 degrees and a -1 correction for 60 degrees. You would interpolate a correction at 37 degrees of about +1, and add that to 37 to get a corrected magnetic heading of 38 degrees.
What else can I help you with?
In order to find true north with a compass you must use an angle of correction called?
angle of magnetic declination
What does ice stand for in relation to prismatic compass?
In relation to a prismatic compass, ICE stands for "Index Correction Error." It refers to the error caused when the index line does not align perfectly with the zero mark on the compass card, leading to inaccuracies in readings. This error needs to be accounted for when taking bearings with a prismatic compass.

What is a lensatic compass?
Lensatic Compass is a kind of compass which uses a magnetized dial, a lensatic compass features a special card which helps the users in reading the directions easily. A Lensatic Compass is very useful device because it has numbers which are useful in identifying the directions of target objects. The use of Lensatic Compass involves difficulties in using it.It is important to learn how to use a lensatic compass properly prior to using it, also other materials like a map and a protractor are also needed when using the compass.

How do you apply Latitude And Speed Correction in gyro compass?
To apply latitude and speed correction in a gyro compass, first, determine the gyro's latitude and speed of the vessel. The gyro compass typically drifts due to the Earth's rotation and the vessel's speed, so adjustments are made based on the vessel's position. For latitude corrections, apply a correction factor based on the difference between true and magnetic north, while speed corrections account for the influence of speed over ground on the gyro's performance. Regularly monitoring and adjusting these parameters ensures accurate heading information.
What is use to find orientation on a map?
Compass
How local attraction affect the use of prismatic compass survey?
Local attractions such as buildings or metal objects can affect the accuracy of a prismatic compass survey by causing magnetic interference. This interference can lead to errors in compass readings and, consequently, inaccurate survey measurements. To minimize these effects, surveyors should identify and account for local attractions during their surveys, employing techniques such as taking multiple readings and using a declination correction.
