[QUOTE="RedDirtDigger, post: 92778, member: 2964"] Between the period of the Minelab 2000 to the 2200 lots of prospectors used large DD coils in Victoria in spots where the ground was very noisy. Some diggings that turned up the deeper gravel with lots of iron minerals were impossible to use a mono on. DD coils definitely had a depth advantage because the monos were swamped with noise. Its changed since then but i am sure there is some ground where some forum members are finding deeper results with a DD???. The SDC may have put another nail in the DD coffin for shallower gold in very noisy ground anyway. RDD [/QUOTE]
