Both are color units with no scratches on the screens. Both units have been updated by Lowrance so that they do not lose GPS position. (these unit were notorious for losing position) I have manuals, screen covers, power cables for both, skimmer xducer for 339 and Minn Kota universal sonar adapter cable for 334. Both units are on Ram mounts, and both have the 2006 Navionics Hotmaps Premium east cards installed. These cards cost 100$ new each. Looking to get $500 for both units.
