Hey guys, I have a garmin echomap plus 73sv and am pretty illiterate on settings and how to use it, but I can use the side imaging and down imaging pretty good. But would like to be able to use the regular sonar and I'm clueless about what settings it should be on to see fish arches or see structure and know what I'm looking at. The down imaging and side imaging has only two settings which is 455 and 800 but the regular sonar has all kinds of beam widths and stuff that I have no clue about, does anybody know of a good video I can watch, or can anybody tell me what to set it up on to get the best images? I hope all this makes sense. Thanks in advance
