But you know the old saying, "Nothing ventured, nothing gained". Its possible that it might actually work! And if so, the peace of mind having it will be well worth the additional cost and engineering.

You could manually triangulate using just one hydrophone. Turn the hydrophone left and right til you get the loudest return then note it's bearing. Then move to other location preferrably at a right angle to the first and repeat the scan. Where the bearings intersect is the likely location of the pinger.
