In the previously linked video, classification of sonar targets is described into 3 levels, with level 1 warranting "immediate investigation", level 2 being a "man made object" and level 3 being of "some" interest

In the event of not finding any level 1 returns will the relatively few in number (8) level 2 returns be investigated?

Also, Peter Foley says there are well over 100 class 3 targets, not 200 as quoted earlier.
