Camera again. The first picture should be of the Face plate Top left, toggle switch..all metal / discrimination.Down to frequency shift.Down to Ground Balance. Red button is pin point button.Big dial is discrimination setter.Up from there is sensitivity, and, above that Threshold..Second picture shows Dave's battery pack modification, as well as the new position for the Black Widow phones to hook into..This would not be a detector to steal, and show up where Tesoro guys hang out..............If it gets above freezing, may take a walk , but no making holes in the frozen turf, cordially Nad
