Sidescan sonar...worth the cost?
I recently sold some rods/reels and have a few bucks to spend. I'm thinking of getting a structurescan HD add-on for my Lowrance HDS7 or a new grouper rod/reel (both around $600). I'm leaning toward the sonar but wanted to get some advice before making a decision I might regret. Anyone using the structure scan and how much more effective do they find it for finding fish/structure?
