I noticed that, but he actually said "could be gleaned" without
electronics.
The modern depth sounder actually give less info than the traditional lead
line,
especially to someone very familiar with the area. Even the old
"spinning neon
tube" sounders gave a lot of useful info. The "tridata" style sounder is
worthless compared to a basic fishfinder.


Spinning Neon :-)) Great arn't they. Fussy bar for soft stuff and clean
ping for bear rocks :-)) I still use one.
