This is the same as the ordinary 5 decade Dominican Rosary. It is merely a question of the indulgences attached to the beads.
On August 20th, 1516, Pope Leo X granted to all the faithful an indulgence of 500 days for every Our Father or Hail Mary said with devotion on the Rosary of the Blessed Virgin Mary blessed by the General of the Crosier Fathers. This was extended later to all priests applying to the Congregation of Indulgences by Pope Pius X.
Any Catholic possessing a rosary having this indulgence can gain the indulgence by reciting an Our Father or Hail Mary. No prayer imposed as a confessional penance, however, can gain the indulgence of the Crosier blessing.
There is no obligation to meditate on the mysteries of the Passion.
The Rosary must be held in the hand to gain the indulgence.
The indulgence is applicable to the Souls in Purgatory.
