Our boat ramps have concrete steps that run down into the water ( flood control lake ) ....... I looked at it on the side scan..... You could count each stair plain as day and had great detail of the ramp itself .....I have over 200 wpts on my "home lake" and know what majority of them are, so first thing I did was side scan the stuff that I knew for sure was to et an idea of what stumps/ brush/ stake beds etc will look like.... It def takes a lot of guess work out of structure..... Once I got my LSS2 ducer at the correct angle I started getting great images
