I have a used Helix 5 unit for sale. Unit is sonar only, comes with head unit, new transducer, new power cord, new transom transducer mounting bracket. Mounting bracket is not included. The unit functions perfectly. 110 TYD or 100 picked up in Tyler TX.
Link to the mounting bracket if you need one (the bracket can be found cheaper at other places)http://www.humminbird.com/Products/GM-H5/
