Finally got to take the D2 for a walk in the park today for about an hour. I have had it for about 4 months and just now got to try it out. In all the years of detecting I have never owned a dd. I took it to an area that I have hunted numerous times with many different detectors and I was amazed at how many coins I was able to find in short order. This area has been used for carnivals and fairs since the 20's and I have dug lots good targets and they still keep coming. What I noticed right away with the D2 was a lot of EMI from a nearby radio tower (I assume). Never was an issue with the concentrics. I used frequency shift to minimize it and finally ended up running the rx down to 5, am 60 and disc at 75. Although these are lower than I usually run at this sight, I was still digging coins and the usual light bulb bases left by the carnies at 4 to 6 inches. Nothing old though this time. One target read a very loud and solid 85 at 5 inches in the lower frequency but it seemed to big to be a coin. At 5 inches I found a pull tab, at 14 inches I actually did find a hub cap. I think this coil can really go deep but it will be a challenge to use on a trashy site. I will probably stick to the 9.5 or the 5.3 Eclipse in the park, the D2 in cleaner areas. All the targets seemed larger than they actually were compared to the concentrics, so I didn't quite get the pinpointing down, but that will come with practice. All in all I am glad I have it and am looking forward to putting it through the paces.
