It is not an different feeling , I do dowsing for 30+ years and before I started I learn a lot from my family that was doing that for many generations. It is not important the composition of the rods , they can be made even from wood, but when you add something to the tip of the rod's, that would make a big difference in dowsing. This is only one of the three possible ways of dowsing ,,,,,,and is not the best one , but this way almost anybody can do the dowsing,,,, and the other two ways depend of every individual. Good and complete dowser has to be able to move the rods with his own mind power ,,,,,,fast and with no mistake's , but during the dowsing he have to think and be concentrated only on the composition he is searching for,,,,,,,,,,,and that could be anything :-)))
