Had a chance to hit a historical place next to a river.The ground is very black and was pretty frozen. The Exp.II was jumping all over the place, making it unusable. Almost like electrical interference. I turned the sens. way down, tried adjusting iron mask and noise to no avail. Are there any thoughts or settings for black sandy soil? Was it the snow on the ground?

Snow should have no effect. Did you do a 'noise cancel' before detecting? How low did you go with the sensitivity? Black/mineralized conditions can be a challenge. Have you used your Explorer enough to try 'ferrous tones' while reducing your iron mask all the way (i.e., hunt in all-metal)? In this mode, iron will give you low tones - consider digging the higher ones. Also make sure your batteries are all good and in tight.
Good luck. I'm fairly new with my SE - the people on these forums have been a great help.

I would think by the way you are describing the ground its mineral composition makes it impossible to detect..Have an old coal breaker real close where I got permission to hunt and will bring any detetor to its knees because of the above. Unfortunately now and then we do find such areas and time to move on...
Went to an old homesite I had hunted before with my EXP II and started to work the field behind it, like I had done in the past. Trouble was my stinkin machine wouldnt settle down for anything unless I lowered my sensitivity to almost single digits. Fortunately I had another brand machine with me that seemed to do much better. BUT before I switched to the other machine I tried EVERYTHING I could think of and had no luck getting the machine to settle down. I dont know WHAT it was that day, but it does happen from time to time. Dont write the site off just yet though. Give it some time and go try it again. You'd be surprised what a difference even a single day can make in a site sometimes.
I would first clean the coil.
I would start the machine a few yards away from the river bank, lower the Sen. to about 10. Go to iron mask and open to 15. Set sounds to Ferrous. Find your clean spot on the ground and noise cancel. Now with this done I would move the sen. up gradually until it starts to act up. Then back it off 2 or 3 clicks. Now start moving toward the river while searching and see how the screen acts. If you find its quiet enough to hunt I would raise the Sen. a click at a time until you find it starting to get nervous Then put it in auto sen.
You know...sneak up on it.

Last fall, it was a corner lot. Big maple trees up by the road. I turned on the machine and it sounded like I was evedroping on a CIA coded message. There was no way to quiet it down other than running the sensivity down around 10. So I walked into the back of the lot... presto everything went to normal. Now here is the wierd part, I walked back up to the road and there was no interference. Then in about five minutes it started again, lasted for a few minutes then quit. This happened probably 10 times while I was there. Not sure what was causing this but I would like to know.

My yard is the same way....somedays the detector works great other days or at different times in the day the detector will go crazy...I also noticed that the TV will have lines on it the same time,so I have decided it is a CB with to much power or maybe a ham operator somewhere.I dont see one close by but sure it is man made.

This is pure speculation because I don't know for sure but I believe the law enforcement & fire dept. have radios that are a little more powerful than average. Could have been that. I know the minelab gold detectors actually pick up transmissions from aircraft. I have been several places when out of the blue I'll get strong interferance & will have to wait until it stops. All I can think is that it's radio chatter....I was at a local lake away from everything by a couple miles when I started getting interferance like I was getting rapid fire target signals...looked around & saw a park ranger about a quarter mile away. Noise cancel didn't work...I waited a few minutes & it stopped....
