Differences between Heatkit GR1290, GD1190 and GD1290

Aug 23, 2015· I am new to this forum Hope someone can clear up my confusion about the three Heathkit metal detector models, the GR1290 the GD1190 and the GD1290? Does anyone know the difference, like operating frequency, etc.? Also, are there modern kits available for a super VLF metal detector? I can only find 40 years old schematics and descriptions.
