No joke with my post. The dark red was reading as if I hand bottom around 100’. Miles of it so my guess is no fish... I have a go7 with a total scan and that reading was blank.. any pointers for settings would be appreciated. On a different trip this was what I was seeing
The blue screen palette is the default . I have tried that white screen and it always looks a bit weird. when in zoom like the pic you posted stuff gets a bit fuzzy lookin. it is just magnifying the bottom portion so gets more grainy. I dont like zoom and just keep it on auto so the ocean bottom is always at bottom of the screen.
Your screen shot shows the transducer setting is 200khz and 2x magnification. The b175h should be run as High Chirp (like Tesoro's image). Did the Go9 recognize the transducer during initial setup? Look in the transducer settings.
