Hi John. Hi there! My name is***** would be my pleasure to assist you with this. The GPSMAP 478 comes pre-loaded with US marine detailed maps for the entire US coast, including Alaska and Hawaii. This should cover Puget sound. However, the 478 accepts optional MapSource data cards, so you can add new maps without connecting to your computer and these additional maps can include a great deal more detail. I believe that either of these two would meet your needs:HXCA015R - Canada g2 HDHUS039R - US All & Canadian West Coast BlueChart® g2 HDYou can see a map detailing their coverage at the link below. They do overlap somewhat so look closely to see which is best suited to you. You may also order them from this link. https://my.garmin.com/mapCoverage/coverage.faces?currency=USD&country=en_USHave a great day and happy boating!
