A 3lb crappie is really rare in most waters. I don't think your odds improve with Livescope because you still have to fish waters that contain a 3lber. I have been fishing for crappie since 1971 and I have only seen one 3lb crappie in that time. Oddly it was caught in the early 70's on a trotline in a lake located right in the middle of Dallas Texas. I would likely be a lake record but dad was fishing for food not records. I have seen some whoppers since then but never a 3lber. I just looked up the Texas state records for crappie and it's 4.56 for a white crappie caught in 1968 and 4lbs for a black crappie caught in 2002.
