I would never 100% fully trust any electronics. ESPECIALLY GARMIN.
The map/depth data just isn't accurate enough !
I've personally witnessed it on several higher end Garmin units. Mine included.

Chesapeake Bay is similar - at least the northern end, very shallow for such a large body of water. I use a Raymarine a78 GPS and it helped a lot when we were there on the 4th. I noticed brown patches on the screen and thought it was sandbars, it's not. There are large sea grass beds that are shallow and should be avoided, especially in a jet boat. Ask me how I know. Thankfully the reverse maneuver works well.
