Used subject many times - only few times i saw it works. tonns of invisible ppl sneak around here and there, cloaking at my sight at 20 game meters approximetely and nothing. they just dissapear - that's all
have no idea how this device works..
anyone please?

Initially, Cloak Tracker only shows the green effect on enemies when they first activate cloak and if they are within a 20 metre radius of you. Upgrade II makes the effect show on already cloaked enemies when they've been within the 20 metre radius for 7 seconds. Upgrade III decreases this time to 5 seconds.

If you're sure they're cloaking within that radius and not showing up then I'm not sure why. I have Cloak Tracker III and everything seems to work fine for me.

Yes. it works very well. I kill everytime with it. One of the best modules.

Best feature is that when someone is cloaked nearby - you can hear annoyng buzz-sound with this perk. It will tell you that the sneaky bastard is near.

I was wondering the exact same thing...
After unlocking and equipping the cloak tracker module and playing for a couple of hours i felt no difference..
But it seems that the first level does not make so much of a difference as the next upgrade levels..

i have a theory that this device does not work if you are cloaked as well as Visor Enhance never light up enemy through the scope if you are invisible.
if Cloak Tracker have the same restrict for using when you are invisible that's svcks...
