Seeker's Compass

Wondrous item, uncommon
This brass compass has two needles: one large, and one small. The large needle always indicates magnetic north and is unaffected by magical effects that would otherwise mislead it. The small needle remains motionless until activated. While holding this compass, you can speak its command word as an action to cast the “locate object” spell from it and activate the smaller needle. This version of the spell has a duration of 1 hour, does not require concentration, and causes the smaller needle to indicate the direction of the object located by the spell. If the small needle can’t detect the item specified by the spell, it remains motionless. Once used, this property of the compass can’t be used again until the next dawn
