I am getting a ice transducer built for it dual 83/200, I could not find one anywhere so it is being built
I made up the foam on it last minute, just to try it and it worked fine, I don't think I will do anything else as I wait for the new ducer
and yes the different colours tell how hard or soft the bottom is
the black line is my small lure when I first start to jig it , the fishfinder sees it as being a bit bigger so it adds some blue and if something is even bigger it show green in it too and if even bigger , yellow will be in the middle of the line, the are about 25 colour schemes you can use, this is just the one that I found easiest to use
but I am still playing/ learning how to use the darn thing
but so far , it's great
