Once we realize the possibility that there may be Sonar scenarios outside the manufacturer's "recommended" xducer mounting concept ..............

It opens interesting ideas of gathering Sonar information from areas in the water column not normally seen with these manufacturer's "recommended" xducer mountings ...

Gene has sent me pix of an interesting example he employs using a DI xducer as "side-looking" ...

Here is Gene's target ...:


He knows there's fish under there ... but where??

Sure ... SI can be used ... but what about DI "looking sideways" ...??

Gene has rotated his DI xducer sideways to look under docks ... with 3 important criteria to mentally visualize what the targets (rendered into the DI image) actually mean...

1. Mentally visualizing the shape of the DI beam ...


2. Mentally visualizing where that DI beam is "aiming" ...

3. A DI displayed image renders "distance to target" from the top of the DI displayed image to the target displayed farther down in the DI displayed image ...

Can you explain what the targets in the DI image below are showing us with Gene's unorthodox "side-looking" DI xducer Setup ...??
