I am far from a good crappie fisherman but a guy down the road who I hunt and fish with sometimes is one of the best locals around. Honestly, he's too smart for his own good at times which can be frustrating but he knows his stuff! He even has the nick name of "Crappie Ed" lol. We have bumped into a few livescope guys and whenever we came across them I shut my mouth, and would just listen to what he'd be asking or telling them. What I have learned is I have yet to talk with someone who wasn't a good crappie fisherman before livescope that turned into one afterward lol.
Stuff like live scope is no different(IMO)than a cell phone in that it will probably dumb people down to what they really need to be doing or learning. Crappie are finicky as heck! Make 100 casts and not get a nibble. Move that cast just a hair in one direction and you have a limit before you realize it. JMHO.
Boats with live scope will be the equivalent to squatted trucks and party boats before too long. Every time you want to hit the lake every bit of structure will be surrounded by these yahoos watching their TV screens LOL
