Chart Dividers is a tool for measuring and dividing distances and angles on nautical charts. It usually consists of two movable legs and a precise dial. It is used to help navigators measure and draw routes, ports, navigation marks and other information needed for ship navigation.
When purchasing a nautical chart index, you need to select a model with the appropriate size and accuracy requirements for use on your ship. Crews need to regularly inspect and maintain the indexer to ensure its accuracy and reliability, and promptly replace damaged or aging parts when needed. When using a nautical chart protractor, boaters need to follow correct usage methods to ensure accuracy and reliability, and record and process measurement data for better ship navigation and ship control.
