Eternal Pose

An Eternal Pose' (永久指針（エターナルポース）) is a special type of compass used in the Grand Line. It is an hourglass-like device with only one orb in the middle of the device, and a needle floating inside of the orb. Like a Log Pose, it records the special magnetic waves of a certain island within the Grand Line, allowing the user to know which way to go to arrive at their destination. Unlike a Log Pose, which resets its recordings on new islands, an Eternal Pose always points to the same island, no matter how long it stays elsewhere. These are used heavily by those who have a home port on a specific island of the Grand Line, as well as by the Marines. They first appeared in Chapter 113 and Episode 67.
