    Finding Shipwrecks, Reefs and Structure


    with Fish Finders
    This page shows fish finder screenshots of shipwrecks, reefs and other bottom structure. An explanation under each image will describe the target.

    Before we start looking at images from fishfinder units, let's look a data from a side scan SONAR. Notice in the image that the wreck has a scoured area of bottom surrounding it. Most wrecks don't have quite this dramatic of a bottom change but normally there will be some scouring which will be a clue that you are close to the wreck.
    This is a screen image of a large wreck off Ocean City, MD. Special thanks go to Capt. Monty Hawkins of the headboat Morningstar for this image. This is from a commercial quality color machine.
    This image shows a wreck. Fish can be seen in the center of the screen. The high section of the wreck appears on the right. Notice in the left section of the screen that the bottom appears very thick. This is the low section of the wreck. The low section may not have any apparent difference in height from the surrounding bottom but the thickness of the sonar image will give away it's location. The red above the wreck is baitfish.
    This image shows another wreck. Notice the abundant number of marks. This is a mix of bait, fish and parts of wreckage. This is worth dropping a line on!
    This image shows a big mix of bluefish and rockfish in the Tangier Sound area of the Chesapeake Bay. Notice the abundant number of marks and the crescent shapes on the right. In this case, we were trolling bucktails on wire line and had 2 fish on each line practically every pass. Notice the tight orientation of the fish to the dropoff.


    These last 4 images are piles of rocks in the Crisfield Artificial Reef. The fish surrounding the structure were rockfish in the 22-26" range.
