    Look what I found in Elm Hill Marina.
    The coordinates on the graph aren’t exactly right since the cursor isn’t on the wreck.
    Also of note… Look at all the bait under my boat. There’s also a car in the middle of the marina.
    The wonders of side/down imaging.

    Last time I launched at West Fork I also saw a boat and a car.

    Is that a Lowrance unit?

    It’s a gen1 HDS8 with a gen1 LSS-1. I’ve been planning to upgrade to a Gen2 or a Touch, but haven’t gotten around to it yet.

    Haha, nice find Simple! Side/down imaging is amazing.

    I just bought a Lowrance with down imaging and can’t wait to try it. It’s one of the cheaper ones and does not do side imaging but it’s a step up from what this poor boy is used to. Do you guys find that you don’t need the standard sonar anymore or do both tell you different information ?

    Downscan and standard Sonar are both useful for different things.
    For instance, individual fish arcs that you see on a standard 2D sonar are sometimes really hard to see on downscan. So, the standard sonar is definitely useful. Downscan can show you things in greater detail for instance – what appears to be a pile of fish on standard sonar is really a brushpile or tree. Also, for some reason, I find standard sonar to be easier to read quickly to keep track of depth changes [probably just the color pops better for me]. Also, downscan really only works well at slow idle speeds 1-6mph, while standard sonar works well at all speeds. Did you get a DSI unit? I would suggest that when you get out on the water, run to some places that you know what is down there just to take a look. Ride over the area with side-by-side sonar/downscan and see what each one looks like on the screen. This will give you a good idea of how to interpret what you are seeing on both screens. If you’re looking for something interesting, there is a blown out bridge on the bluff wall side of hole-in-the-wall island. Take a look at that. There’s also a ton of cool stuff out at Old Hickory [flooded dam/locks, bldg foundations, roads, etc…]

    I can see schools of fish and detailed structure using SI that would otherwise be missed by regular sonar, but I usually split screens to get the best of both worlds. Have seen the bridge remnants at Hole-in-the-Wall… pretty neat. Lots of tires on the bottom of creeks.

    It’s definitely easy to find schools of bait with sidescan and downscan.
    It’s also possible to find individual fish. I just find it easier to separate gamefish out on the regular sonar due to the color separation. I have seen schools of crappie and white bass when idling around on sidescan. In my screen image with the boat, you can see a ball of bait on the top right of the screen. I run the sidescan or downscan on an HDS8 while watching the sonar on an older LCX in the dash. Like degaman said, best of both worlds.
