David, Side scan simplified is just two bottom sounder units turned on
their sides with an array of transducers to form a narrow beam. A past
member of this list has (had) a great web site depicting how to build one with
two economical Hummingbird units and 8 puck transducers (4 pucks per side wired
in series-parallel configuration). With the advent of the economical Hummingbird
(Model 997 ???) side scan unit that Carsten has described on his web site, home-built
becomes moot for the power of this unit. Just build a fish and add some
cable to have a very powerful unit. It is not an ultrascan unit. R/Jay Respectfully, Jay K. Jeffries Andros Is., Bahamas Talk sense to a fool and he calls you foolish. - Euripides (484 BC - 406 BC) From:

Bartsch A question about side scan
sonar....Is side scan sonar essentially an ultrascan machine designed to work
in the ocean? I just was just curious. Get
