My testing of Garmin 8410xsv (8610xsv) and GT54-UHD is coming to an end, but yesterday I took a short trip out to look at a wreck in the fjord. Saltwater, depth and range in METERS (multiply by three to get feet).
As most brands, Garmins has zoom-functionality on their SideVü. Here you see a gaping hole in the deck of the trawler from where a winch used to be. This has fallen through the now rotten deck.
And a school of baitfish to round it off:
Conditions where windy, and there was quite a bit of murky freshwater from a nearby river on top of the saltwater. On my way to the spot with the wreck I got the chance to play icebreaker as well.
The same wreck (in slightly better conditions, less wind) with Lowrance can be seen here:
