What is the correct way to scan with the CLU?

• A. S-shaped pattern left to right
• B. Radar-sweep horizontal left to right
• C. Circular scan starting at top
• D. Lazy W method going right to left

Answer: (D)

When using the CLU to search for targets, you need a sweep that covers the area thoroughly and keeps threats in view as you move. The Lazy W pattern achieves this with shallow zigzags that roll across the search area, creating overlapping swaths like a relaxed letter W. Sweeping in a consistent right-to-left direction gives you a steady rhythm and an easy mental map of what’s been scanned and what remains. The overlaps ensure nothing is skipped and targets can be seen from multiple angles if they’re briefly obscured by terrain or foliage. Other patterns either leave gaps with simple straight or circular sweeps or enforce abrupt turns that can disrupt tracking, making the Lazy W the most reliable method for CLU target acquisition.
