If a radar has a variable range marker, the ranges to targets can be read directly from which feature?

• A. The cursor line
• B. The variable range marker
• C. The target's speed
• D. The bearing ring

Answer: (B)

Using the variable range marker lets you read ranges directly. The VRM is a movable marker drawn at a specific distance from your own ship on the radar display. When you align the marker with a target, you read the distance off the range scale at that marker’s position, giving you the target’s range instantly. The bearing ring and speed information don’t provide a direct distance readout, so they don’t serve this purpose.
