Side scan pics

[ScubaDude]

The wind finally laid down for a day. I got to drag my side scan around and get some pics. This is a 440' liberty ship, and a 110' tug off Wrightville Beach, NC. The image quality went way downhill when I finally got the file small enough to upload. I'm working on another place to post them.

Enjoy,
Brad

She would have looked like this before she was sank. It looks like the upper decks have all collapsed in, or she was swept to avoid her being a hazard. How deep is she, what happend to her as the tug was with her?

I would love to see a full res pic, how many htz is you side scan?

She is part of an artificial reef when they sunk her they used a little too much TNT. The site is 50' deep the upper most structure is at about 18 to 20 feet. The tug was also intentionally sunk next to her. I tried to crop it down smaller but I don't have any good editing software. Plus there is some cool smaller stuff in the bottom of the image the squigley thing on the left is an old mooring for a bouy I think. The site was one of the original car tire reefs and you can see tires randomly throughout the image. The snowy looking stuff above the wreck is schools of bait fish.

The side scan is a Marine Sonic. This was imaged with a 300kHz fish.

That's awesome.
What's the least you can spend to get into sidescan?
If you ever get up around the Outer banks and need some deckhand help let me know.

Parker, check out the Humminbird 987C SI - Side imaging fish finder for under $2,000.

Brad, REALLY nice scans but I don't see the galleons....where are they?

The Liberty ship is sitting on top of three spanish galleons, and two german subs......................not.

How does the Hummingbird unit work in normal sea conditions 2-4 foot? I would think that with the boat and transducer pitching and rolling around the the image quality would suffer pretty quickly.

It's not too bad for a cheap solution, I'm planning to extend the cable and build a towfish for it. Nothing fancy, but it will take a lot of the motion out of the equation. I've seen some scans done a really rough lakes that were decent, not great, but decent. The conditions rivaled a calm sea in my opinion.

Hi Brad
Great images. Maybe next summer you could bring it down here and we could go searching.
