I usually give it about 10 minutes and then move to another Crappie Condo (brush pile , stake bed, ect) . i fish all depths top to bottom bumping cover . Then if no takers or just dinks I move on . I fish a 1/8 oz tube jig with a 11' jig pole with 8 lb line almost 99 % of the time . Here they bite purple/chartruse or they just not biting . Just need to get a pattern on depth , type of cover and how tight they are holding . Sometimes if bait gets near cover they hammer it and other times you need a slower presentation with bait hitting the cover. Because they refuse to move far to take a bait at times .
