Goldmaster V-Sat & Goldmaster III, Goldmaster 4B and GMT
accessory
search coil. Elliptical 4x6 inch "DD" design provides
superior
performance in extreme ground, better sensitivity to
physically smaller
metal targets, performance in extreme trash and
physically smaller foot
print for working around obstacles. Longer
but narrower detection window
compared to similar sized search
coils. Finds the good stuff in areas
littered with trash.
