Tracking Your Chronometer's Accuracy

This log book gives navigators a dedicated place to record chronometer error and daily rate over time, information that is essential to accurate celestial navigation. Ruled pages allow for consistent, methodical entries so that any drift in timekeeping can be tracked and corrected for.

A useful companion for anyone practising traditional navigation by sextant and chronometer, whether aboard a working vessel, a cruising yacht, or as part of a navigation course.
