How it behaves in a real fight
Your ESP draws a line or cone out of each enemy, pointing where their camera is aimed. When that line swings onto you, they are looking your way. When it points down another hallway, their attention is elsewhere. The indicator updates in real time, so you can watch a player sweep a room before you commit to the fight. Do not confuse it with a snap line. A snap line runs from your screen out to the enemy. View angles runs from the enemy outward.
Many builds also feed the direction into the radar, which reads faster than a cluttered screen in close quarters. Builds differ in which ESP toggles they carry. Check the feature list on the product page you are reading, and ask support if you need a toggle confirmed before you buy.
How to use it without drawing attention
View angles is read only information. It never touches your aim, so nothing about your mouse movement changes in a killcam. ESP only, with no aim assistance at all, is the lowest risk setup there is.
The real risk is how you act on what you see. Pre-aiming a wall at head height, every single time, looks exactly like what it is. Let enemies come into view before you start tracking them. Give yourself a beat of reaction time instead of turning the instant the line moves. If you also run an aimbot, keep the visibility check on so it does not target enemies through walls. Set aim smoothing to 5 or higher so the aim moves like a hand rather than snapping like a machine.
