Well, based on the advice on this forum I've finally beaten my skunk! I limited out on prawns on Wednesday in an open area East of Sidney. I have discovered the Genesis Live feature on my Lowrance chart plotter and it is a game changer. I was able to develop a detailed map of an area and find a couple of ledges that didn't really show up on the charts. I think Garmin has a similar feature called quickdraw contours or something like that. Thanks for the advice!
