I can confirm that spectra detector realy works. I've tried before other long range derectors (e.g. AKS) and the results were poor... Now for the 1st time I can say a long range detector worked for me. That is Spectra. For sample targets of 10gr gold jewels was no problem to detect from 25m away. Target was hidden at 50cm depth in the garden soil. Some practice is required to handle L rods but results will soon come. In conclusion: do not hesitste, give it a try!
