A little more info about the DR.ÖTEK MT12

Note the above specifications are subject to change.
That operating frequency of 18 kHz is particularly interesting for two reasons. First it may explain the poor performance of this machine on the wet salt sand. Beach mode does not help. But also 18 kHz is suspiciously close to that used in the Fisher F19 (19 kHz), Fisher Goldbug (19 kHz) and Teknetics G2+ (19 kHz). All of which have been cloned by the Chinese over the past few years.

The controls on the MT12 resemble those of the Fisher machines and the "ground grab" (ground balance) is exactly the same terminilogy and function used in the F19 and Gold Bug machines. Could it be that the firmware in the MT12 is the same as that used in the Fisher machines and the Chines clone machines such as the Tianxun TX-850?

Of course it could just be coincidence and the machines all use similar features etc
