How too tell which coil you have on your machine

TARGERT ID STABILITY

IRON MASK SETTINGS

XT 70 SET-UP

How to change from Coin/Treasure mode to Prospecting mode is done by pressing the Mode Auto Button.

Target ID stability is activated by holding down the MODE AUTO button for 3 seconds it may be turned own or off by this method.

BEACH GROUND is activated by holding down the GROUND BALANCE button for 3 seconds which will turn on the beach icon it may bet turned own or off by this method.

GROUND BALANCE (NORMAL)
Ground Balance (Normal) is suitible for inland use and operating when the beach icon is off.

(Coin / Treasure)
An unbalanced detector in Coin & Treasure Mode will blank continuously (if a pattern rejecting -8 is used) or detect -8 continuously (if a pattern accepting -8 is used).

(Prospecting)
An unbalanced detector in Prospecting Mode will produce a continuous 'warbling' sound that differs from the sharper sound of a real target.

Iron Mask default number is 5, which is best left there if you jump from Coin/Treasure mode to Prospecting mode to check & see if you have located a Iron Object then go back.

Use Tracking Ground Balance on the Beach if targets are located far apart.

Some times on the Beach you may have to reduce the SENSITIVITY settings below 15 which is the Default for the Beach.

Tiny ferrous junk targets might be detected when the Sensitivity level is set too high for the beach. Decreaseing the Sensitivity of the X-terra 70 may stabilise it, reduceing false signals and interferance, and assisting in differentiateing between signals caused by soil mineralization and metal targets.

To test your soil conditions:

One of the ongoing common mis-conceptions is that the Ground Phase Number(Ground Balance)represents how much mineralization a particular soil
matrix contains. The mineralization of course referring to minerals that cause poorer performance of a metal detector, and not a particular quantity of an inert material.

The Minelab X-Terra X-70 has a hidden feature which allows you to make a reasonably accurate assessment of your ground conditions including the iron(Fe3O4, black sand) and/or the conductivity(salinity) of your soil. To clarify, you can quickly measure in relative terms how magnetic or connductivity of your ground is. You can then jot those numbers down and compare them to any other X70 users in the world.

As a matter of fact a database or registry could be set up to compare your conditions to that of others. Therefore when an X70 user states that they have "high mineralization" which is hampering operation, it can easily be verified whether such is the case.

The procedure is really just an extension of Auto-GBing the X70. So don't become overly concerned that it is terribly complicated, it isn't.

Procedure in Normal GB mode with GB Tracking "OFF" and Sens=20:

A. Auto-noise cancel in the area you will hunting with the coil held 3 feet above the ground and parallel to it.

B. Locate a target free area of soil.

C. Engage Normal GB & remain in the GB screen.

D. Place coil on the soil. Do not press the coil against the ground! This will distort the coil shape and give an inaccurate result. Simply allow the weight of the machine to lightly keep it against the ground.

E. Press the Auto GB button and raise coil about two feet above the ground before Auto GB has completed. If by the time you reach the apex of pulling the coil up to two feet it doesn't complete, then pump up and down from just above the ground to two feet high as accurately as possible. Recall that Auto GB signals with a tone when completed.

F. While still in GB mode press and hold Patterns button to get the numbers. The numbers are six digits in length but read out in three groups of two
that will repeat if the Patterns button is held down. Therefore 99 99 99(almost a million) is the largest number possible and 0(00 00 00) is the smallest.

Forty-six thousand would appear as the following sequence, 04--60--00. Make a note of the numbers which we will call the "IRON NUMBER"(Magnetite...Black-Sand).

G. As a reference, numbers in the thousands are mild ground, medium grounds tens of thousands , and hot hundreds of thousands. For clarity:

1. 0(zero) >> 10K mild ground.
2. 10K >> 100K medium ground.
3. 100K >> 1M hot to scorching.

Procedure in Beach GB mode with GB Tracking "OFF" is done the same way as the method above:

The same as above in normal GB except that your are measuring conductivity. Great for Ocean beaches, salt flats, & dried up lake beds etc. I would also take three samples in the exact same spot and average them to get an average number, using either of the above procedures.
