"Is it useful?"

Fire Dance shook her head lightly, "Not very, but somewhat." It's a valuable skill, but it's not easy to use this system well. Just like real radar scanning, the radar operator has to distinguish whether a blip is a cloud, a bird, or a plane. A cruder radar can only make judgments by comparing movement distances manually. Advanced radars provide data based on the difference in speed detected in two scans: moving speed, size of objects. When necessary, it can also lock onto a target continuously.

Clearly, Fire Dance's scanning skill was still on par with a World War II-era radar, but it was still a radar.

Lin Wu used Stealth, and Fire Dance followed, passing through two subway cars before Fire Dance tapped Lin Wu's shoulder. It was then that Lin Wu turned to look at Wai and saw its eyes bulging out. He patted its head to comfort it and told it to wait as he himself felt his way out.
