I am not. My boat has Lowrance HDS units, old school. A long time ago, when I got my first boatful of electronics, I found myself effing with those more than I was fishing. Eventually I settled in using electronics for GPS/mapping, water temps, and bottom density only. I'm a techy guy, but I'd rather just fish than mess with electronics when I'm on the water.
I've been back to coaching baseball, so I'm not on the cutting edge of lake fishing for the last few years. I witnessed livescope while in a boat only 1 time. I was only marginally impressed. I've seen all the headlines of the huge fish taken using livescope. Apparently it works pretty well. To me it's disturbing, yes. Makes sense that bigger bass (that wouldn't otherwise be caught without LS), especially during the spawn, could be targeted using LS, then have the normal mortality rate when caught, and upset the balance of the school.
Can you deplete a lake of crappie using LS? Not sure you can blame that on LS, that's gotta be more of an illegal take situation to me.
