I talked to a very good fisherman at Jigfest this year that is using Livescope for crappie. He told me how he pulled up on some cover, scoped it out, and spotted 6 crappie. He could also tell one of the crappie was bigger than the others. First cast he caught the big one, caught two more and then let his buddy catch the other three. No more there so on to the next spot.
As far as bass fishing, I've been watching some of the live coverage of BASS and BPT. Some of those guys are fishing jerk baits. They make a cast at the bank, then start working the lure watching their screen the entire time. Patrick Walters wacked them in FL doing that, but he did not win, he did finish somewhere in the top 10. Lee Livesay won on Fork last year throwing a 110 and also walking the dog. He claims he could not only see the bass and how they reacted to his lures, but he could size them and knew which ones to target.
A few days ago at the Big M ramp I talked to a fisherman that is now using Livescope. He is not a tourney fisherman, but is a regular on the lake. He says it has changed the way he fishes, easier to find them and you can see how they react to your lures. You find some trees that are out in 70 FOW that top out 30 feet below the surface and if there are bass in the tops, you can see your lure and keep it in their face.
Last year on the Johnny Morris million dollar tourney, there were some guys from Kentucky fishing 50 yards away from me where there were deep fish schooling. They were using the scope to spot fish in 50 FOW that are roaming around in open water. They did OK, don't know exactly where they placed, but they fished the last day. Watching some of the live coverage, it was obvious that the guys at the top were using it to catch deep fish.
I see it as another tool in the toolbox. A very useful tool, but like any tool, you have to know how to use it.
