Al-be, looking at this pic, now the fishfinder he has placed there makes some sense....he removed the original, and mounted his own, just didnt do a very good job..he backed it with plywood, so it looks like crap. I thought he just cut a hole in the dash and mounted his there. They came that way, hummmm
Really glad I used screws instead of rivets on the wave shield, it made running the transducer cable so much easier.
Very impressed with the color and resolution of the 551. I'm using a split screen, dv for structure detail and 77kHz for fish arches.
Note the arches indicating fish to the left of the bump on the 77kHz screen. They show up on the downview screen but not well enough to take a picture of them.
