Anderson Rods

[michael]

Hi. I had connection with a man who claims "Anderson Rods" are very valuable and
accurate in detecting special metals you bait it among the radioactive material that is among with device. I told him there is no major difference between them and other rods and are influenced by factors that affect on other kind of dowsing rods. He didn't accept and persists on his idea and claims this device is the result of physic scientists labour during so many years and the first model was invented in 1940!!
Is there anybody has experienced them?
Another thing; Can you introduce the most famous & useful book with complete comments about LRLing or even dowsing?
Your answers will be appreciated.
