Lowrance Structure Scan Settings

I've got a structure scan on my boat that I got to find good diving spots, but I can't get it to work properly. Is there a best pallet, contrast, range or other setting that I should use?

What settings does everybody use?

I know it's a tricky question because on fish finders everbody has their personal preferences on the clutter, etc...

Structure Scan

I would suggest you spend a day on the river to have a play with it and work out what is best for you,learn settings etc.
Chase some flattys and look for the drop off's.

not really a whole heap of settings for structure scan as such - why do you say it's not working properly??

Palette doesn't really matter so much, set range for 30 meters to each side to start with (unless you had a big screen to spread the picture over) and maybe go slightly wider once you work it out

note if your over a relatively flat bottom you will see very little as there is no structure to see.

 I use the blue pallet on

 I use the blue pallet on mine as I find it the easiest to read set sensetivity to about 75 and go from there...you want it to be just casting a black shadow around any rocks or whatever you have gone past...455 khz I think it is will give you the best detail  and never use the auto range....set it to 3 times the water depth your in...10 m of water set it to 30 either side.

hope this helps.
ive got a screen shot somewere ill post to

I'm going out on the boat on Saturday and will give it a go. I'll start with your settings Jayden and take it from there.


Thanks for the info guys.

New boat new sounder

We have just got back into boating and the boat came with a lowrance HDS 9 gen 2

This is so much more complicted than our last one.

We cant seem to work out how to navigate to a waypoint.

We marked home then could not see where or what to follow.

I have looked for tutorials on youtube but they only show how to mark them and move the curser to one.


Help please


Cant see what sort of fish it is, you could need these ausspecs.com.au
