OK...first off...When entering a new forum, it pays to read the posts already there, at least the last 100 anyways...most of the time your question can be answered in this way, or by searching the forum for keywords, such as "fast tracker".
To more possitively answer your question, if you live on or near a historical landmark, or site, your in very good luck...I would say you chances of old coins and relics is much higher this way. the Fast tracker is a capable machine, but do not hold the assumption of most new detectorists, that every time you go out, your gonna strike it rich. Go out with NO expectations whatsoever, and you will NEVER be dissapointed...I do not hunt to get rich, or to find silver and gold on every outing. I hunt for the simple thrill of not knowing what I might dig up next. Check your local laws...Make sure that where you plan to hunt is not gonna bring a rain of trouble down upon you...Stay away from Private property (unless you get Written permission to hunt there). Monuments, memorials, State and Federal Lands are usually bad places to detect (check first) Authorities can confiscate everything you have with you at the time they catch you (detecting gear, your car, etc.). You can also face Prison time, and very hefty fines. In my city, the tresspassing charges are $350 at a minimum, and or 90 days in jail. School yards and playgrounds are normally safe spots to hunt (but again, common sense dictates that if a tot lot, or school is in use by many children, their parents may not look kindly on someone weilding a strange device, and carrying what appear to be potential wepons lurking near). Research research research...90 percent of metal detecting lies in research...look up your local history, over a wide range of years...do google searches for "your city, state" and civil war, or revolutionary war, etc. Look at your area on Google Earth, and search for open fields or large orpen areas you may hunt, then find out who owns that property and if you might gain permission to hunt there.
Have never heard of anyone finding a grave with a detector, but I can imagine it HAS eben done...Stay FAR AWAY from grave sites...It is usually frowned upon by the public, and in many states, digging within so many yards of a graveyard is a Felony. The caretakers of the yard DO NOT have the right to tell you it is OK. Burial plots are PRIVATE property...
read the manual for your detector 10 times over, and practice with it while reading. Bring the manual with you (a copy of it) on your first hunt. You do not know how frustrating it can be to have to go home to figure out what a particular button or sequence of buttons does if you do not remember.
Follow our code of ethics (I am sure it is printed on your manual somewhere...Usually near the front, or on the rear cover)...
learn to dig proper plugs...Always fill in your holes, and strive to leave the ground as you found it...When your done, you should be able to look back in the ground you covered, and not be able to tell you were even there...
I hope these words help you in your new "Addiction" (It is far more than a mere hobby)...Never be ashamed to ask any question...The only dumb question is the one that remains unasked...
I do not want my warnings to scare you away from the hobby...I am a straight shooter, and tell it like it is...This hobby has brought me much enjoyment, but you MUST use your brain at all times...The one question I ask myself all the time is, "Am I doing the right thing by hunting here?" if I say no, I pack up and move on...
Happy Hunting,
