Please don't regard him as an "expert"; he's getting quite old and thinks that "fadiddling fumble-putz" is a more accurate description.

    Thanks Ben, I have structure scan on a Lowrance and looking at the undersea world sideways and split down the middle like a filleted salmon takes some getting used to but its a fabulous feature for those of us that need detailed bottom info.

    Ben, can you please explain more about the relationship between the sidescan and downscan systems? Lowrance’s marketing materials and documentation are very hard to interpret on this point.
    What exactly is DownScan? And what role does the standard (non-StructureScan) transducer play in rendering the imagery?
    I’m considering an HDS-5 + LSS-1 for the dinghy but want to understand the transducer configurations before I pull the trigger.

    Adam, the downscan imagery is generated with the same LSS transducer as the side viewing window. In fact, I don’t have a Broadband Sounder box or transducer attached to Gizmo’s Simrad NSE system.
    If I did, I might be seeing more fish, though that’s a bit hard to presume as Maine fish stocks are not great. It’s common to run an LSS downscan window alongside a sonar window because the first details structure while the latter is better at spotting more ephemeral targets.
    In fact, I just recently learned that you can overlay downscan on sonar, or maybe it’s vice versa. You can see what it looks like in image #3 of this slide show:

    Thanks, Ben. That clears it up.

    As someone just about to instal a full Simrad NSE system with broadband and structurescan this is wonderful stuff.
    Thanks Ben for all the great information you provide.
    cheers Peter

    Here’s a neat video about StructureScan from Team Old School:

    Hi all,
    On a slightly tangential topic, are there any true forward looking contour trackers or sonars available for pleasure yachts?
    Although the StructureScan technology is interesting, it doesn’t seem to be particularly useful for entering new harbours, or poorly charted ones, etc.
    None of the main guys (Simrad, Furuno, Raymarine, etc) appear to offer a true forward looking depth contour instrument.
    Any input?

    If yuo add Garmin to your list of the main guys then you can expect to see forward array sonar from Garmin using Interphase technology. Search “Garmin Triple wow” on Panbo and you will see Ben’s entry
