I use different things as a pendulum. A necklace, anything that will swing!!
I would like to share my story of the missing wallet. I held a party at my place on acreage. 'Twas quite a wild night! Most camped overnight and the next day, a friend ,I hadn't seen for a while, told me he lost his wallet. Everyone looked all around. No wallet. When you are mixing different people together you know (well you hope you know) your friends but others may not. Think he thought one of my other friends had flogged it.
One year later, it still bugged me about the missing wallet, so I got my swinger and asked to point the direction of the wallet. I ended up over at the shed and tried not to influence it. I was getting mixed answers and tried for ages, but nothing.
The next day my young son was gathering leaves behind the shed and putting them in a wheelbarrow. Guess what gathered up with the leaves?? A wallet with $200 in it! I had great pleasure ringing my friend to say I had found his wallet
I may not have found the wallet with my pendulum but it opened up the energies for it to be found.
Ps I always ask for 100% white light guidance and ask if I can use it at that time.
