Fam got me a Garmin 178C Sounder for my bday in 2005. It came with my choice of a data card that contained all charts (about 150) that covered all of Puget Sound north to the top end of Georgia Strait. A year or so later I bought a second data card that contained all charts from Everett, WA to Alaska and the west side of Vancouver Island. I’ve been using these ever since and find them to be very accurate in every respect. I keep the Garmin mounted at the helm for waypoint and routing input while underway.
