Being I'm a Hillbilly from West Virginia I'll start this off by saying,
[size=large]"Metal Detecting Code Of Ethics"[/size] (well a starter list anyway)
* I will always check federal, state, county and local laws before searching. It is my responsibility to "Know The Law"
* I will respect private property and will not enter private property without the owner's permission. Where possible, such permission will be in writing
* I will take care to refill all holes and try not to leave any damage
* I will remove and dispose of any and all trash and litter that I find
* I will appreciate and protect our inheritance of natural resources, wildlife and private property
* I will, as an ambassador for the hobby, use thoughtfulness, consideration and courtesy at all times
* I will work to help bring unity to our hobby by working with any organization of any geographic area that may have problems that will limit their ability to peacefully pursue the hobby
* I will leave gates as found
* I will build fires in designated or safe places only
* I will report to the proper authorities any individuals who enter and or remove artifacts from federal parks or preserves
Now, here is a list of some common terms,
All-Metal: Any mode or control setting allowing total acceptance of all metal types, iron, aluminum, tin, nickel,
gold, brass, lead, copper, silver etc...
Audio ID: Circuitry which produces different audio tones (pitch) for different target's conductivity.
Black Sand: One of the most extreme components of non-conductive, negative ground minerals. Magnetic.
Also called Magnetite (Fe304) or magnetic iron oxide.
Cache: Any intentionally buried or secreted hoard of valuables.
Conductive Salts: One of the major mineral types which make up the positive ground minerals. Wet ocean
salt/sand will produce a positive response due to its similar conductivity to metal.
Conductivity: The measure of a metal target's ability to allow eddy currents on its surface.
Depth: The greatest measure of a metal detectors ability to transmit an electromagnetic field into the ground.
De-tuning: Method of manually or automatically desensitize a metal detector so that it may locate the center
of a target.
Discrimination: Circuitry which ignores or otherwise indicates, a specific target based on its conductivity/
phase.
Drift: A loss or increase in threshold caused by temperature, time, or battery condition.
Eddy Currents: Small circulating currents of electricity.
Ferrous: Descriptive of any iron or iron bearing material.
Frequency: The number of complete alternating current cycles produced by the transmit oscillator per second.
Ground Balance: A state of operation in which specialized circuitry can ignore the masking effect ground
minerals have over metal targets.
Hot Rock: A rock which contains a higher concentration of mineralization than the surrounding ground.
Matrix: Refers to the total volume (average) of ground penetrated by a metal detector.
Menu: Series of listings and prompts on a visual display designed to aid the operator in feature selection.
Metal: Metallic substances: iron, foil nickel, aluminum, gold, brass, copper, silver, etc...
Microprocessor: An electronic component that can be programed to perform certain electronic functions.
Mineralized Ground: Any soil containing conductive or magnetic components.
Mode: A condition of operation selected by the operator for specific functions.
Motion Mode: Any mode that requires loop movement to respond to metals.
Non-ferrous: Not of iron, any metal that is not iron.
Non-Motion Mode: Any mode of operation that doesn't require movement of the loop to respond to metal
targets.
Phase: The length of time between eddy current generation sustained on a metals surface and the resulting
secondary electromagnetic field effect on the loops receive winding.
Pinpointing: Finding the exact center of a metal target.
Reject: An indication of a target non-acceptance by silence or a broken sound.
Sensitivity: The measure or capacity of a metal detector to perceive changes in conductivity within the loops
detection pattern.
Signal: An audio or display response alerting the operator that a target has been detected.
Stability: The ability of a metal detector to maintain smooth predictable performance.
Target: Refers to any object that causes an audio or display indication.
Visual ID: A feature which creates a visual indication to aid in identification of a target.
VLF (Very Low Frequency): A metal detector that operates in the 3-30 kHz frequency range.
This should help get you started.

You should head on down to the 20th Century Tales section of this site and post a few! Everybody is pretty great here and will help you out and want to read about what you are finding and doing, so welcome, and go find something!
