John, 
The Fisher unit is more like $7,800.  and is a towable fish with a graph 
print out.  Never used one, don't know much about how they work -- except 
the very general principles.  I want to help locate wrecks in the 
150-300fsw range off, for instance, San Pedro were there are lots of 
wrecks with locations generally known, but need to be able to use 
something to search large areas fairly quickly as compared with the depth 
sounder.  For example we know of a wreck of a 150ft. steel oil rig ship 
in 140fsw and it's approx. area of sinking (north of Santa Barabara in 
this case), but the search area is still a few square miles-- far too 
much to do with just a sounder and search pattern unless one got very 
lucky.
