Does anyone else experience a fishfinder showing 200+ feet in 4 foot of
water for a few seconds then showing the actual depth? Is this normal or
should I call humminbird?



It's not that unusual to get false depths on sounder, particularly
for a seconds. Some things that seem to help include keeping the
transducer clean, making sure the wiring is of large enough diameter
and properly connected at both ends, and being careful not to run more
than one sounding device at a time from your vessel. I often see
situations where somebody is running a sounder on a flybridge and then
goes to the lower helm and turn on another sounder without turning the
first sounder off. In cases where there are separate transducers
rather than slave units I suspect they get confused about which echoes
to recognize.

I upgraded to a new sounder a few years ago. Even though I only have
one sounder on my boat, (there is a backup unit that never gets used),
the old unit produced a lot of false intermittent readings. The new
one, by Raymarine, is much better.
