Effectively fishing deep / offshore hard or soft cover is IMO,
what separates the best bass heads from the rest. And you can interpret that as you prefer.
I do not have FFS, never even looked at one operating.
But it is Not needed to fish what's listed above effectively.
Does it make it better or easier, I can not say.
Posts like this lead me to believe folks are looking for a FASTER way to get this done.
Many feel FFS can do that. I do not know that either.
But what I do know, is that locating hard & or soft cover on the best structure
can lead to some great bass fishing.
But it takes time to find it, learn how to do it and then present baits effectively to get bites,
and to fish it.
The following are the 'tools' I use when looking for & fishing the deep stuff
and to get my baits on the the spot on the spot.
Map study, Triangulation, Side Scan, Down Scan, AS360, way points, marked buoys precise boat control (Trolling motor) and even more exactly boat positioning and finally casting angles.
The presentations the work for me in these situations depend on several factors that in all honesty, are the same in 3 ft as they are in 30 feet.
BTW- In my fishing any water shallower
than my 1875 Pro-V bass is long is 'shallow' and I can usually see the bottom, meaning the fish can see me. That changes things.
Good Luck
