I think the effectiveness of a fish-finder as a sub-tracker is going to 
depend upon the angle of the echo cone produced by the transducer.  Too 
narrow a cone and you will have to travel over the sub to locate it, 
which will be anything but effective as you'll have to employ a 
grid-search to chase it down.  A forward-scan sonar would make more 
sense.  Assuming the sub shows up as a recognizable target and the range 
of the unit is decent, you could literally turn the boat 360 until you 
located the sub.  I think a forward-scan sonar would probably be better 
than even side-scan for this purpose.
