Is your machine unable to separate targets that are close together? Hence there will come different detectorists who’ll bring different machines with them – and will seize your finds. Watch the video: why a detector needs the recovery speed.
The test is performed with a Polish-made Rutus Alter71 detector, new product 2016. Many people are skeptical about this machine (me too, I don’t like its price).
Clearly, though, it’s not an ordinary detector: frequency change in the range of 4.4-18.4 kHz, mixed mode, recovery speed adjustment, wireless headphones. All info on a Rutus Alter71 is collected here.
