Axiom Side Vision

gmckenzie,

Thanks for including the requested additional photos. The latest transducer installations photos appear to show an optimal installation of the RV transducer. As the outboard/outdrive shaft is aft of the relatively narrow fore/aft beam of the RV transducer, you should achieve good viewing to both port and to starboard. With respect to interpreting SideVision imagery, the closest portion of the imagery displayed will be no closer than the transducer is proximate to the object within the water column. Within your screen snapshot, the image clearly shows the three bridge columns on the starboard side of the vessel. The closest portions of the returned bridge column imagery appear to be plotted approximately 11' from the centerline of the plot. Given that you had stated that you passed approximately 8' from the bridge columns and that the transducer is located approximately 3' inboard from the starboard gunwale, it would be expected that the closest point of the bridge column would appear approximately 11' out from the plot's centerline. I may be incorrect in interpreting the image, but there also appears to be sonar imagery from bridge columns on the port side, located approximately 75-80' from the centerline.
