Log Pose

A Log Pose is a fictional, compass-like navigational device; a necessity for traveling the Grand Line. In Japanese, the term is represented by the kanji phrase 記録指針 Kiroku Shishin, which literally means "Logbook Compass Needle" (a reference to its function), but it is pronounced "Rogu Pōsu." In the English-dubbed anime produced by 4Kids Entertainment, it is called a "Grand Compass."
