Double Mando

Definition: A Double Mando is a mandatory route that requires a disc to pass between two designated objects, usually trees or poles. “Mando” is short for “mandatory.” The disc must travel to the right of the left-hand marker and to the left of the right-hand marker, staying out of the restricted planes defined by the markings. Together, the two sides create a required gateway along the hole.

Why It Matters: A Double Mando narrows the available throwing route and places a premium on accuracy, angle control, and disc selection. Course designers may use it to direct play away from nearby fairways or public areas, prevent shortcuts, or preserve the intended challenge of a hole. Players must consider how the disc will turn or fade as it approaches the opening. A controlled shot through the gap can be more valuable than a powerful throw that risks missing it.

Term Observations:

A Double Mando is also commonly called a “double mandatory” and is often marked with arrows pointing inward toward the required opening.
Two trees forming a natural gap are not automatically a Double Mando; the mandatory route must be designated.
Under PDGA rules, if any part of a thrown disc clearly enters a restricted plane, the player receives one penalty throw and plays from the designated drop zone, or from the previous lie if no drop zone is provided.
Hitting a mando tree does not automatically mean the mandatory was missed; the disc’s path relative to the restricted plane determines the ruling.
A Double Mando controls the route on both sides. Adding an overhead restriction creates the familiar three-sided opening of a Triple Mando.
