[QUOTE="mbasko, post: 229022, member: 4485"] Yes but as Lee says in the right ground. The SD2000 & SD2100 were in fact supplied with mono coils but you will find most in Australia would have found the DD to offer more stability in a wider variety of conditions thus they became coils of choice for most SD users, not so much that the SD was designed specifically for DD's. And in saying that there were a lot who swore by the supplied 18" mono dust bin lid on both & the 8" mono on the 2100. Being new to detecting & IMO a DD will serve you better until you are more comfortable with the detector Ben but if a mono is all you have & you find it ok where you detect don't sweat on it. A mono can give better sensitivity to small gold & more depth but if you are suffering with ground noise then it's pretty inconsequential anyway & a DD may be required. Like Lee I also used a mono coil on a SD2200D which I found ok in a some places but not all. Both the standard Minelab 11" DD & Coiltek 14" DD pro elite ran well in pretty much most places. I used to be pro on using a mono all the time but over time have come to realise there is definitely advantages in using a DD where conditions dictate especially on, but not limted to, older machines.
