Six inch DD coil?

[Onus]

I hunt in some really junky areas so I bought a six inch double D coil from Kellyco. Can someone give me some pointers about the difference in the double D and the regular 11" coil on the Safari. I haven't had it out yet, just waiting on the weather. Onus

I may never know! But if I find out, I promise to share! Onus

They are both "DD" configuration and the 6" will separate targets in trashy areas better than the Pro.

Ok, so now I have the 6" DD coil. As a test run, I went to a local kiddie park that I have hunted a thousand times in test runs. I know it is loaded with junk and crap targets. I did find 4 zinc pennies and the little coil was capable of separating them out from the other junk. They all gave a high pitched repeatable tone and read 34 on the numerical scale, but showed up as just barely in the silver zone on the linear graph. After finding the first two I was able to call the remaining two. The coil did not seem to do too well when swinging too close to the various steel anchoring posts on the sand pit. I turned the sensitivity way down to around 8 and could only get about 8 inches before the post set the detector off. The darn steel posts showed as silver but not coin and when I moved in to about 6 inches or less it changed to an iron overload. At first I thought that there might be a coin up to within a foot of the posts and just to be sure I dug 3 of those signals down to black hard dirt and found nothing. I had read where a detectorist had been finding overlooked jewelry up next to the iron posts, but not with this set up. Well, first time with this coil. If anyone has experimented and found different please chime in. Onus

Sitting here watching the snow fall, only snow of the year but starting to accumulate. It's 31 Centigrade here now but supposed to be 63 by day after tomorrow! Anyhow, I've been doing some rereading of Andy's book and air testing on my Safari. I am on the chapter about ferrous and conductivity. I've read it 3 times and still can't figure out the difference. I have the 6" DD coil installed and was air testing in Coin first and it showed c for conductivity. Ran a series of objects across the coil and noted the detector's response. Then I switched to All Metal and the little icon showed an F for ferrous. Ran the same objects over the coil and got the same readings as C. The tones sounded the same to me also. According to the book the tones should be different, but they don't seem to be on my Safari. I ran the machine on all factory settings, low trash density, auto sensitivity, threshold 8 and hit the noise cancellation between every object. And one thing I have noticed is that in auto sensitivity, it always remains in the max position. Also, my 14k Gold wedding band came in at 31, copper and it showed a ring icon. I thought it was supposed to come in around 18 in the gold range? That don't sound right to me? Comments please? I was consistently able to get a good clear tone on all objects at about 7 to 8 inches. So the depth looks good. Onus

don't use the safari but on my soverign and large man's ring read 173 which is in the zinc cent range.

Hello everyone. Just got my six inch double D coil from Kellyco yesterday. I got up early this morning a headed for the local school. The school was built in 1956 so I wasn't looking to find much as far as old coins. I put my Safari in all metal with the sensitivity at 18. After 2 hours I had found 8 Penny's and a dime. Three of the Penny's were wheat's. 1940 being the oldest. I am very pleased with the Safari so far. All 9 of the coins came in at 37 on the reading. Until next time, good luck to everyone.
