Forget your bow sonar unless your using Active, the passive mode is next to useless (I saw no visual indication of a 30knot cavitating VicIII that was a mile away. But I could still mark it).
Remember to use Buoys when Zig Zaging so you can keep tabs on what has left your TA's sensor area when you ziged, a skilled skipper can sneak in though the hole.
And keep your helo(s) sweaping the area ahead of your SAG with buoys.
