already explained this the other day.
A good predator doesnt even use target isolation to find the fireteam because they know they are going to be mudded up. especially at the start. I basically use it only to find pigs and when iv already found them and they are in buildings etc to see whos where.
I rely on map and spawn point knowledge. to go to the general location and i listen. you hear panting/sprinting sounds and the voice lines of the fireteam, shooting, AI voice lines, camp alarms…
I can see flocks of birds fly up into the air where you run. taking it out wouldnt make the slightest bit of difference only hinder those that havnt learned these skills yet.
I can find the FT in less than a min without even using it.
Just use it when i hear pig sounds then go and get the pigs.
