SHOWING BOTTOM WITH A HIGHER SPOT ON EDGE OF SONAR
fish laying on bottom
Soft bottom? No clue
A complete guess. Buried hard layer of some type.
Not enough info ..... how fast is boat moving?
That is 83 Khz with a pretty wide beam and not as good of target separation ..... You could look at it with 200 Khz and DI / SI unless this is only a 2D unit.
Maybe a somewhat softer bottom like sand which would absorb echo a little more with maybe a log downed
Complete guess though and hope to learn something new

Frequencies (in any sonar) are "tools" ...
Low frequencies have generally larger beams = more coverage - less detail ...
High frequencies have generally smaller beams = more detail - less coverage ...
If your sonar has the option to display both frequencies at the same time (2d) ...this split sonar view will have both "tools" working for you at the same time ...

Nice job speckfinder and thanks for quiz Rickie!
Doh, took too long to answer! Was letting others have a crack at it first. BobB and I seem to think similarly!
Better be careful .... That could get you in a LOT of trouble ....:RoflQuote:

We should note for those following that the HB DI units have 2d beam frequencies of 200kHz/455kHz (conversely the non-DI Units have 2d beam frequencies of 200kHz/83kHz or 200kHz/50kHz) ...Quote:
