This listing is for a used (like new) Hanna Kroeger Stainless Steel Dowsing Pendulum. I tried to learn how to use this pendulum, but I have no talent. Many years ago, I met Hanna at her shop in Boulder, CO. and witnessed an amazing demonstration by a true healer that used a pendulum (just like this one) as an aid to help diagnose health issues. Hanna used it with precision, and I was astonished at her speed and accuracy. These pendulums are sold at Hanna's Herb shop (which is where I purchased this one) for about $22.00. You can buy this one for half the price, plus shipping.
