Fished several times with a buddy that's had one for some time ... pushing jigs & casting/flipping to brushpiles. I now have one, but have only been able to use it twice. Yes, it does take a bit more concentration when casting/flipping jigs to brushpiles/submerged trees, but it will get a little easier with time. Yes, you will see many fish come to your lure and then swim away ... but, they'd have done that anyway & you just wouldn't have known it, and maybe even thought the cover didn't have any fish on it.

Most of the fish I've caught while fishing with Livescope have not been felt actually hitting the jig ... when one is right on the jig I've just raised my rod tip a little & felt weight, so I set the hook. Whenever I see the jig pull away from the fish & don't feel any weight, then I just lower the jig back down or slightly jiggle the rod tip. Sometimes that provokes a bite and sometimes it spooks the fish back to the cover ... but, I've yet to see them move completely off the cover, or even return to a deeper section of it. They generally just go right back to the position they were in before my jigs got to them. And they will react to the jigs pretty much the same way on repeated casts.
On the other hand, my buddy has seen them spook from any action other than a gentle glide. He's also seen them move to the opposite side of the cover when one of them is caught and taken from the school. On one particularly clear water lake, he's even seen them move away from the cover if the boat gets closer than 20ft from them. He's also seen massive schools of Crappie, yet has only been able to get a handful of them to bite.

The biggest "advantage" a newcomer to Livescope can have over any other newcomer to Livescope is having a bunch of waypoints to try, to begin with. You will find more as you move around from one previously known cover spot to another !!
