that was a interesting read and will i think that a white bottom is a great idea and will be looking into that myself. Have only had the JRC ff50 for a few months now and havent really looked deep into the functions and only played with it on the water. Used to have a koden aswell before going to the jrc and yes both sounders do read slightly different to each other.

you have hit the nail on the head and so many people over see such important info
If you want fish you need to put the time in and find that spot x away from others.
a good example of this would be Harry Akinson reef in the middle of the bay. fishing on this reef might catch you the odd fish and lots of rubbish but fish around and away from the reef on little structures will see the qaulity fish come aboard. (at times )
