Minelab 8 inch coil

[JHM]

It's hard to take it off once you put it on. Since I got it I've found 8 silver dimes and a ton of wheats in one of those "cleaned out" areas. One thing that works well for me is to run in all metal. When I find an iffy signal next to junk, I switch to coin-jewelery mode and check it. Most of the time, it will cut the junk and let the coin sound off. I also like high-trash with auto sens. Seems to be working in this trashy area. Thaught I would pass it on.

How do you compare it with the 10.5" coil, if you have that one? Sounds like you've got a great coil there, that's working wonders in the trashy areas.

The 10 inch is good in cleaner area. I'm mainly hunting in trash right now. I like the DD design better than concentric. It's just my preference.

Hi JHM, the DD coil covers the ground more completely than a concentric coil, with a single sweep. The entire length of the strip between the DD coil, covers the ground. So overlapping the sweeps is minimized. With the DD coil, it takes a little practice to pinpoint accurately. Like yourself, I love the smaller coil for trashy ground, and I'm happy to hear that you find detecting in trashy ground, not as overwhelming as some might think. It does take practice though. When I first started detecting with the Quattro, I began in the worst ground possibly, for a beginner. But because I lived on the goldfields at that time, and I knew it was going to be productive, I just had to perserver. I remember thinking "what the hell is all that noise?". But I got out each day, before and after work, and kept on with it, fiddling with the settings. I even took Andy Sabich's book out with me, and many a time, I read it over and over, between detecting. I would did everything up, first in coin/jewelry mode, then began to use All Metal mode. In no time, I started digging relics, and learned to diferentiate between a good signal, and iron siganls. Then the negative readings, and the low tones that come with them got me confused. But the key to learning the Quattro I found is to dig everything, until you start to put the pieces together, so to speak, about the tones and signals, the high and low pitches, the irratic and even sounds. Everything tells you something, and on the goldfields, you can't rely on the numeric readouts entirely, unlike on the beach, where the readings are more true to the targets. My favorite setting on the goldfields, with loads of trash, is manual sensitivity between 12 and 14, on High Trash, but sometimes I've been able to up the sens to about 16, but not often, as the detector sometimes does get a bit erratic. Hope you continue to find lots of keepers JHM!

I used to only use low trash. But I have went over spots I hunted in low trash with the high setting and found more coins. I've had some problems with those one way signals but I'm getting better at it. Sometimes I will switch over to coin made and recheck the signal. This seems to help.

Golden, that's interesting what you said about your settings on the goldfields. My first thought on that would be: "I'll bet she had to set the sens down a bit because of the hot rocks". Let me know if you think that's why, because I would think on a normal, reasonable beach, you could run a higher sens setting, but I keep hearing all this stuff about hot rocks, and I'm totally uninitiated, because I've never detected any goldfiels, yet. Just curious, as usual. Not trying to give you a hard time, but I'm sincerely wondering about that? Marc.
