Is it deserve to buy?
 

Hi to all
please give me advice about this long range locator that called TFR-Dowsing rod in the link I appreciate your opinion

Notice there is 4 models. I prefer this one

If you know to dowse then you don't need this.
Two simple L rods are ok and make the job without money...
