Pendulums can be a fantastic source of insight. Your crystal pendulum can be used to receive a ‘yes’ or ‘no’ answer to a specific question you may have. 
 
When you first receive your pendulum you need to program the yes or no response.
To do this, place one elbow on the table and let the pendulum dangle from your fingers. Ask a simple question that you know the answer to be true (e.g. if your name is Fiona, ask “Is my name Fiona?”). Remembering the answer is already a ‘Yes’, see which way the pendulum is swinging. Clockwise, back and forth, anti-clockwise; whichever way the pendulum is swinging is your ‘Yes’ movement.
Then do the same for a question that you know to be false so that you have your ‘No’ movement identified.
 
Next time you want to receive a simple Yes or No answer to a question, consult your pendulum as you did above.
Make sure you care for your pendulum and approach the consultation process with respect, otherwise your answers will tend to be idle and confusing.
