well its ordered and my first fcv620 colour sounder should be here next week ,seeing as so many people on this site seem to use them or the 585,6100's etc ,i was hoping that some of you would part with your knowledge and experience in the setup and settings of this sounder instead of just using it in the auto mode and not getting the best out of it,in a previous thread some wants to find prawns with his sounder,surely they cant be that good
