The PMR-II was developed by building on the same principles used to build the Precision-Master Rod, together with improvements that make this an entirely new instrument. The PMR-II uses in its power tube a powerful combination of mineral crystals, together with a radioactive stimulant. We believe you will be amazed at the results you get with this all-new instrument. The PMR-II is second only to the top-of-the-line PMR-III. The unique two-hand bearing handle allows perfect balancing of the instrument for steady operation. To use this new handle, hold it as shown in either of the two pictures, with the power tube level. Initial reports from customers who have used the PMR-II with this handle are very favorable. This handle contains two sealed ball bearings on which the instrument pivots so it can turn in a practically friction-free manner. Also included is a bearing handle for one-hand operation. To use the PMR-II with either of the two bearing handles, just load the power tube with a sample of the metal or mineral for which you wish to search, extend the antenna and hold as shown in either of the pictures. When held in this manner, the instrument can swing freely right or left in the direction of your treasure or mineral deposit. The PMR-II is operated with the 24" handles and the spring handle in the same manner as the Precision-Master Rod. The PMR-II can be used to search for gold, silver, diamonds, lead, copper, mercury or any other metal or mineral. The quantity of radioactive material in the power tube is minimal so it offers no hazard to either the operator or to bystanders. The user response and praise of this equipment has been extremely satisfying for us. It is our opinion that any serious treasure hunter should have an instrument of at least this capability in his tool kit. Chances are that the first treasure you unearth will more than justify the modest cost. The PMR-II is one of the finest dowsing instruments build and in performance is second only to the PMR-III. The instruments of the PMR Series are the only dowsing instruments that use a radioactive source to stimulate the power load.
