I’m probably not terribly far behind Kristine on kayak cost (probably past her actually since I also set my wife up with one) and I also have no illusions about ever leaving my day job or the massive paycut I’d take to be a “professional fisherman”…..
That said, I run FFS on my PA14 and have a Garmin 106sv dedicated to it. I honestly don’t think it was a huge game changer for me. I’ve been fishing for a long time and the only thing that I saw as a massive improvement was side imaging because it let me eliminate unproductive water faster.
FFS has actually done the opposite for me. If I find them, I KNOW they are there and I’ll waste twice the amount of time trying to make uninterested fish but something that I would have spent seeing them on sonar, casting what’s feed at the moment, and moving on.
While I won’t get rid of it as maybe one day, I’ll learn to move on quicker, it definitely isn’t make or break for me. Side imagine is what I feel I can’t live without, especially tournament fishing new bodies of water.
