I strongly disagree. I have owned several makes and models including Humminbird, Lowrance LMS350a, X-85 and Eagle Ultra 111. There is no question that my Raytheon L750 is the best, most accurate sonar I have owned. I fish sturgeon often. One area is around the Trojan nuke plant. I can find the troughs that hold fish without a problem. Down around Astoria I can pinpoint sturgeon, kings and silvers. It has fantastic bottom separation and easily picks up diamondbacks lying in the bottom. I cannot tell you how many times I have found oversized sturgeon at Bonneville. My opinion...two thumbs up!
