Not sure how that's possible .... if it's showing bottom, and there's something ON the bottom, then it would show it very plainly. Maybe there's just not anything down there that your DI ping is running over :dono
I'm lost too, I'm on truman lake in Missouri. i am positive there is something down there occasionally. stumps and trees everywhere
Have you tried going back to factory default. :twocents
Is this the HELIX 7 DI with a dedicated DI piezo ... or the HELIX 7 SI that has no dedicated DI piezo and gets DI data from the side imaging piezoes ...??
Rickie
the latter. helix 7 SI
Core series HB SI units do not have a dedicated DI piezo in the SI xducer to collect DI Sonar data from directly under the boat ... (MEGA, ONIX, and SOLIX do) ...Quote:

There still should be some things in the DI image ...
It may help to mark a good brushpile or stake bed with buoy markers and scan repeatedly with different settings to see what the changes do ...
