See if this helps. Go down to the diagram at the bottom of the page.

Not sure about the Hbird, but a towfish sidescan is about frequency, the transducer array and spacing of the transducers and the narrow cone angle. You can see a frog hair with the tow fish sidescan.

Similar principals I would expect.

The side imager works more like an ultra sound than a traditional LCR! The returns are alot stronger.

Actually most any unit will pickup PVC if adjusted properly.

I agree. I'd only add that being able to know that it's pvc on a normal unit is a lot harder then what I'd imagine it to be on an SI unit.

Just got my 797C2 SI this week and got it mounted to the Boat. As soon as it warms up, I'll head to my favorite cove where I have two 10FT PVC trees sunk and some assorted 5gal buckets with PVC sunk.

Ernest, quick question: I've only done some sample recordings from simulator mode, I converted them using the HBSI sonar file converter and I've looked at them in both programs (yellowfin and Deepview) and I like the results. I'm assuming that the results will be limited by the pre-recorded file that HB put on the unit, and what does the ping speed really do in real-life recordings. So do you set the ping speed to a certain setting, or let it run on Auto?

That is the only question I have, without actually getting the unit out on the water. I've spent a couple hours sitting in my garage looking at all the menus and settings trying to get an idea of what I'm dealing with.

Sorry to overload you with info, or hijack this thread. Thanks in advance.
