Ruler is Su in conjunction with Ne, so first look at places near photographic equipment, tobacco, alcohol, medicine or near some object of glass. Ruler is in cadent house; cadent house means that item is either far off, or close by, but hidden and almost impossible to find. This will take time to find, usually indirectly by a third party. It may show it is to the left side of places that I would suggest for search.
Look in bathroom or kitchen, near aquarium, near liquids, chemicals, oils (for healing techniques for example). Look also in a bedroom in a closet. Look near religious areas at home.
Ruler in 9 house usually indicates item is far away.
Look near some church, college or law “things” at high shelves or around vacation pictures or travel literature. Also look at library (high shelves).
Near colour:yellow, red
POF is also in water sign Sco. It to can be in a bathroom, toilet, next to water pipes, or near something that holds water, in a dirty part of the house where rubbish or junk is kept, trashcan, room or desk where unpaid bills are kept, in an “empty” room, wash room, secret drawer or chest, in a hiding place. Because POF is in 5 house search any romantic places or any place of pleasure or enjoyment. Also look near the heating system or fireplace.
Direction: North by West

Because Su's dispositor is Ju and Ju is ruler of 6th house, and 6 house represent servants, might be it is with owner of cab! Or because Ju rules 10th house also, might be phone is at police station, or at your mother;s house.
