Sonar gets even better when you get the resonance augment; it makes it a lot more efficient since you don't have to keep reapplying sonar every 10 seconds when your team cuts down the first set of enemies you applied it to. Resonance also works as another way to extend sonar's range, since the sonars caused by it start from the enemies killed rather than banshee herself.

The only drawback resonance has is that there is a short cooldown between the procs (no more than 3 seconds), and there seems to be a bug where sometimes the sonar dots won't appear on enemies (this didn't happen before I got resonance, so I'm assuming it's the cause).
