The advantages of projection magnetic compass compared to other magnetic compasses.

The projection magnetic compass is also called the projection magnetic compass, which can be used to observe the position of the ship through projection. Projection magnetic compass is suitable for indicating azimuth and guiding direction on various ships. The characteristic of the projection magnetic compass is that it can be used as a standard magnetic compass or as a steering magnetic compass. The height of the lens barrel can be adjusted arbitrarily, and it can also be rotated left and right. The projection magnetic compass system consists of a projection magnetic compass and a heading device. The magnetic projection compass can be installed correctly according to the attached manual. When installing, you need to connect the power supply correctly. If the power supply is connected reversely, the fuse will be blown. After it is blown, you need to replace the fuse. When not using the projection magnetic compass, you need to turn off the power of the distributor. The plug of the distributor is a push-pull type. When you pull the plug, you cannot rotate the plug.

     Every time you sail, you need to carefully check the projected magnetic compass and record it in the logbook. Why do you need to check and record the log? This is to ensure the normal use of the magnetic compass, and each recording is convenient for calculating the magnetic deviation and deviation, which is very useful.
