A wellbore dart or pill is provided such that each time the dart passes through a downhole tool having a seat, an externally extending finger is forced radially inward into the dart. As the finger moves inward to its depressed position, the finger moves a ball or other placeholder from a first position to a second position. When the ball is moved to the second position it may be released into the interior of the well bore or into a chamber in the tool. Once each of the balls have been released from the second position the finger is locked radially outward causing the dart to land and be locked in place at the next seat that is encountered by the dart.
