The "video made by a Lowrance guy" has been debunked some time back. Alas, false info doesn't go away in internet land. Blended down view was/is used by some HB for several years now. No feedback about that. LWinchester2 (bassboatcentral) has put up some tests with blended versus dedicated dv on the Garmins. Essentially, unless you are deeper than 30 fow minimum there is no negative impact. I have the Garmin 93sv chirp with dedicated piezo for dv. I am happy with this unit. I have basically no experience with other brands and results. I had two trips with my late buddy and his HB--he bought a Garmin later. And one trip with a friend who had higher end Lowrance. His was very good, but cost almost three times as much. Bottom line is I find a lot of cover and catch my share of fish. I won't tell a guy to buy one over another. I do know that the Garmin works well for me, and is really easy to use. Important point when you're not the sharpest knife in the drawer. I do have experience in that regard.
