I have a one year old lowrance HDS 5x no gps, sounder only. it was put in my dads boat as a replacement for a b10 trip. it was in a boat for three days and that's it. no transducer or power cable (you can get those anywhere) i do have a flush mount kit for it and the box, but no instructions, or manuals. unit it self is brand new. the cover is scratched from sitting in the sounder box but other than that no issues what so ever. I did just put a brand new gimbal mount on it.
$400 obo they retail for $600 i figure $70 for a transducer and $20 for a power cable (high figures) your still ahead. it is also dial in for river/b10 fishing. i had the guys at fishermans set it up before my dad left last year.
