Yes I tried with my pendulum for the lotto numbers

didn't work
I also calibrated myself and it said 520ish...
I found recently with mine you can ask : Yes / no but also greater than and less than...
The last to I found recently. You have to say show me a YES. Show me a NO etc.
For me
yes is a diagonal upper left \ to lower right
No is clockwise rotate
Greater than anti clockwise rotate
Less than diagonal upper right / to lower left
Hope that helps
ps where you spiritually need to know an answer I have found it to give you alternative answers for your development shall we say. I was asking it questions about my Dad's health when he had cancer etc but I was in fear of him dying and that is 100 so there you go.
