My boat has two DF's ... a b/w 2d HB in the console, w/tdx mounted in the bilge --- and a Lowrance Elite 5DSI mounted in the bow, w/tdx on the TM. My DSI unit, even if transom mounted, would only work (produce good images) at speeds up to 40mph. My boat runs in the low/mid 50's @ WOT ... besides that, even at 40mph I would most likely be more concerned with where I was going & what was on the water in front of me, rather than trying to punch my way thru the menu buttons to mark a waypoint (or even keep tabs on what the screen was showing).
SI is great for showing you what's in the general area ...
DI is great for showing you what's in a specific section of that area ...
Standard Sonar is great for showing you what's in a select space of that specific section of that area.
SI & DI work better when combined with GPS capabilities. But, none of them are of much use if all you do is fish the same spots, on the same lakes, all the time. Yet, when faced with an unknown body of water, or area of a known one that you haven't fished before ... any of the three are better than none of them.
