Hey Ernie,
I would approach a super trashy area like this:
1. Go for the easy stuff first by going over the area with some serious discrimination. Make a coin program by rejecting all targets, and then learn in only silver coins and pennies. Put sensitivity on 17 manual and don't worry about depth or nulls. Use the 7.5" coil and overlap swings 50%. Go slow. To determine how slow to go, lay out some pennies and pulltabs about 3 inches away from each other on clean ground. Alternate the pennies and pulltabs. By slowly sweeping over them, you can determine the maximum speed that will allow you to hear each individual item. Activate the FAST mode. When you come across a repeatable signal, it is probably a coin. But before you start digging, switch to iron mask -15 so you can listen to and memorize the sound of the signal. I think it is important to use heavy discrimination before you switch to iron mask. The reason is that iron mask can cause you to waste time by making you listen to and ponder hundreds of signals when you could be cruising around getting all the easy stuff first with your coin program. Once all the easy signals are gone, you are then forced to start spending loads of time considering iffy signals. At that point, it is time to switch to IM -15.
2. After you have high-graded the easy stuff, it is now time to go after the coins that did not show up through all that discrimination. Go to iron mask -15, and use the same sweep speed and the 50% overlap. Each sound you come across that falls within the coin pitch range should be examined. When you hear the first hint of coin pitch, get over the target and do some rapid little 3-inch sweeps over it in order to develop the signal. Check it at 12:00, 2:00, 4:00, etc. If you find that the signal becomes consistent (repeatable) at a certain sweep angle, you need to dig it. Expect to find alot of rusty iron objects. Go over the area in a couple different directions since many of the hard-to-find coins only show up over a limited swing angle (maybe only at 4 O'clock.)
3. Some guys (like Bill W.) are expert at IM-16 which I think is the ideal setting for trash since you hear every signal and no nulls. For now, I stick with IM-15 in order to minimize the number of rusty iron objects I dig.

I've been hunting lately in -16 IM, ferrous sounds and it makes the going alot faster in iron infested (HotRocks) areas I've tried -15 and it seems to slow the machine down so I went back to IM -16 it probably depends on the area UR hunting in.
Some very good points you suggested Mike!

I don't consider myself an 'expert' such as Mike Unruh said I was... <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt="
"> But, I would approach sites in much the same way Mike has talked about. Use some discrimation to get some of 'easier' coins. I use the stock coil almost exclusively in trashy areas and have done quite well. I don't own the 7.5 or the 8 inch coil that are available so I can't tell you from personal experience what's 'better'. I have heard both the Sunray X-8 and Minelab 7.5 are both good in trashy areas. I mostly hunt in IM-16 with ferrous tones. But, FERROUS tones are only advantageous around iron trash IMHO. If you hunt where there are alot of pulltabs and foil I would suggest using CONDUCT tones. Which you use depends on what kind of trash is in the majority. Most of the sites I hunt are near 200 years old and usually have alot of iron trash. I would suggest if you can... is find a place such as a farm field that was previously a school or church that you can dig without having to worry about grass, etc. Then you can dig your 'iffy' signals and learn what the Explorer is telling you. Learn to go by tone ALONE and use the LCD as a reference but not as a definite answer. Sometimes around iron coin will hit anywhere on the screen and have a good coin tone to them and not be anywhere on the LCD where coins should be. I have had coins hit one the upper left, middle upper portion, straight across from nickels, and lower right of the screen. If it wasn't for the proper tone I would have walk right by these coins. The first thing you should do is get the common trash (especially iron) that you encounter doing your outings and place them close to coins and see how the Explorer reacts. This in itself did wonders for me on what the Explorer was telling me around trash. What I would also do is make your sounds menu your back button. This is done by going into the sounds menu then hit the 'detect' button. Now every time you want to switch between ferrous/conduct tones just hit the 'back' button on the Explorer and you can switch between the two tone selections. Now you can get a 'second' opinion with the Explorer sounds. Believe me the Explorer can be frustrating in the learning stages but it kicks butt once you start learning the sounds and what they're telling you.
