Thanks ref

This is also true. In some instances you'll still get a "we're being pinged sir", because the sonar is being pointed in your general direction, but it doesnt mean they have a hard fix on you... yet. Some quirk with the WE ive never been able to understand.

Ref's the man!

With multiple escorts on you, there is ALWAYS at least one that is listening for you.
