Thread: Sonar Quiz #30

I took the bottom left corner of the image and enlarged it so that I could paint stuff on the actual image ...



We know the unit should be able to correctly calculate depth (aka distance) to a target because the equation the unit uses to calculate this distance to a target is constant (except for water salinity) ...

So the bottom depth calculation (25.3') and the distance to "Fish ID target" calculations (24') should be correct ...

So it seems my HB 1197 with software version 6.310 "paints" the Fish ID icon below the actual target echo (strong color blotch) ...

What we should learn from this is that if a certain software version does indeed include a "depth label" to a Fish ID icon ... We should trust the "depth label" more than where the Fish ID icon is "painted" in the water column ...
----------

What I can't figure out is how to turn on "depth labels" to Fish ID icons in my Onix to know how far away fish targets are from the Onix xducer ...
