lowrance 522 or 527

pikeman Posted 1/28/2008 2:22 PM (#65480) Subject: lowrance 522 or 527 I want to replace my junk sonar with a decent maping one but don't know which one to get. Should I get the 522 or the 527 with the dual freq transducer? Anyone have either of these or have a opinion on them? jerry Posted 1/28/2008 4:16 PM (#65482 - in reply to #65480) Subject: RE: lowrance 522 or 527 Member Posts: 2567 Location: Manitowoc, WI The need for a dual frequency unit depends on how you use it. If you fish the big lake and use downriggers for salmon and trout, then the dual frequency is for you. If you fish smaller, shallower bodies of water, then I would recommend the single frequency. Good luck with your choice.
