The thing that helped me be more productive was when I went to the LakeMaster SD card on my Humminbird Helix and learned how to use the Depth Highlight option. I set my depth highlight to a depth I think the crappie are hanging out or to the depth I plan on running my cranks. Typically I'll highlight 15 feet +/- 1 foot.
Right now baitballs are very scattered as well as the crappie. As the crappie get over the funk of spawning and start to school up near the bait, you'll start to see multiple catches in certain areas.
