I target them on tip ups. You'll miss a few, and I usually go with smaller thin fat heads, 6# florocarbon leader to 40# tensile power pro braid{I have a bulk spool for surf casting}, #10 red gamigatsu salmon egg hooks through the bait's lips, and to mark the depth on the spool I use a heavy split shot on the top of the spool, so that the weight of the shot upon the take spins the spool without much force and the crappie don't feel it. I'm using old school wooden tip-ups.
I also fill the spool to capacity so the start up force need to spin the spool is much lighter. Last, I put small alligator clip-on cow bells on the flags so as soon as I get a flag up I hear it and get there.{I'm usually intensely focused on jigging}.
I've only ever caught decent sized crappie, about 10"-12"+, on the tip ups. The smaller crappie seem to spit the hook quicker.
I definitely catch more jigging though than via tip up.
