Yes combo unit, only lacking maps if that is important to you. GPS does all the usual stuff like log your track, speed, show position, waypoints, man overboard key, bearing/heading etc. But it is the sounder side of things I purchased my 7SV for and it is an excellent performer with quality screen and great features and performance. I've owned a few Hummingbird sounders over the years but at this price point, the Garmin is in a different class IMO.
