This is the one thing anyone can get out of Huna immediately. Get or make a pendulum. (Easiest way - a bit of thread and the tab of a soda can). Spend a few moments to set up a yes/no system of pendulum signels. Then, sort of play 20-questions with where the object is. Usually, once I ask what room an object is in, I find myself standing in front of the object once I move to the specific room.
