Humminbird 688 sonar/fish finder with Nav and mapping. Includes Lakemaster Norhteast region software and some really neat
mounting gear that lets you remove it all if you don't want to leave it on the boat. When I purchased this unit, retail was about
$600 and the software was over $100. The mounting stuff is custom and really well made. I also have a manual with detailed
instructions on how to get the most out of this set-up.
