Controversial long post coming.
Forward facing sonar is in the cross hairs of a lot of people today. It seems you are either for it or against it. No in between. Each side argues their points. I have Livescope and Active Target both on my boat. It has not made me a pro fishermen. In fact I think that whole argument point is dumb. I could buy a grill and smoker and put them on my patio but that don't instantly make me a pit master. Just because I have the equipment to be one, doesn't give me the knowledge or skill by just possessing it. Forward facing sonar is just like that to me...it requires its own set of know how. Trust me...seeing fish on a screen doesn't mean you will be able to catch them or even ID them.
Carp, gar, and drum are pretty defined. But the others...I have no idea some times what they are other than a school of fish that look like big bright orbs. Just cause you can see em, don't mean you can catch them. I learned that a long time ago coming from the trout streams of ultra clear water. I've wasted a lot of time casting to fish I could see that paid my bait no mind. It hasn't changed with Livescope. I still catch most of my fish by trolling...just covering lots of water and never seeing any fish on the Livescope forward screen. Where it HAS impacted my fishing to some degree is if I am wanting to fish lay downs, docks,.etc. Before, I may have a bank stretch with 20 lay downs. It would take some time to fish them all and see which one or ones held fish. Now I can just go by them and point the transducer towards each one and skip the ones that ain't got fish on them. But that still don't mean the ones that are on the trees, will bite.
I personally think the biggest overlooked technology in fishing that has made the biggest difference in how and where we fish...is sonar map cards. Prior to them, we had paper maps. Maps that were composed of pre dam/flooding data. 40-50+ year old data. A lot had moved and changed in those years. If you went to some bait shops, some times they would mark up a map for you for a few dollars...giving you community holes. Otherwise...a lot of fishermen back in the day, used the bottom bumping rig to find channel drops and that sort of stuff. Now...you have recently scanned and mapped sonar cards with community edit capabilities. They are highly accurate and with contour shading, etc, makes it SUPER easy to find those sweet spots on a lake. Or easy to follow ledges, creek channels, etc. No more blind wandering around. And EVERYBODY has access to the same cards and data.
