Pendulum Not Responding To Me

Hello,

I recently purchased my first pendulum. I bought it together with my husband and we both began to use it.

Lately, however, it was responding more to his questions than mine. I've read to keep the pendulum on my body at all times so it becomes attuned to my vibrations. Should I keep it on me at all times or should I just let my husband keep this pendulum?

Thank you,
Milly
