Depth lines in the DI image would indeed help determine how far each target is from the xducer ...

Remember in a DI image - the xducer is at the top of the DI image (or 0 feet depth) ... Every target below 0 feet depth is "x" distance away from the xducer ... In Gene's case, sideways from the xducer ...

The digital depth readings in this type of scenario should not necessarily be used as criteria ... because the unit is "looking" for a hard return to determine digital depth - and a sideways aiming DI xducer is pointing the wrong direction to obtain this hard return to determine digital depth ...

In Gene's scenario of a DI xducer turned sideways - we should should only focus on the displayed targets and how far they are from the xducer - and use the mental visualization of the shape and direction of the DI Sonar beam to deduce where there targets are ...
