Which statement is true about the Centerhold Technique?

• A. It is a method used with the Lensatic compass
• B. It is a method used with a protractor
• C. It is a surveying technique
• D. It is a map-reading method

Answer: (A)

Centerhold is a technique used with a Lensatic compass to transfer or derive a bearing from a map by centering the compass on the map and using the sighting features to align with the desired line. The design of the Lensatic compass—with its center pivot, sighting wire, and rotating bezel—supports keeping the device steady while you relate map directions to a real heading. This makes it a compass-based method rather than simply using a drafting tool like a protractor, a broad surveying technique, or a general map-reading method. A protractor measures angles on a map without a compass; surveying covers field measurement methods; map-reading is broader interpretation without necessarily employing the centerhold technique. So, the statement that Centerhold is a method used with the Lensatic compass is the correct description.
