For use with Coils:       9" and 11"

This is a two tone program that worked a treat when tested on in ground targets out in the field, why use more than two tones, even if you have 3/4 tones your going to dig all but the low iron tone anyway, so where's the point, just leave the low iron tones, and dig the high tones, if you get a mixed high/low tone, scrape some soil away to get closer to the target, also check any iffy signals at 90 degree's, another trick to suss out an iffy signal is to approach the target with the front of the coil, as the front of the coil comes up to the target and it gives a low tone, you can be pretty sure it's an iron target, and if that doesn't help dig it out. Just to add to the above, you may prefer to set the "Iron Volume" to 0, which then gives us a one tone program, it's just personal preference, either way performance is the same, please choose the correct software version

1.        [Discrimination]................. 4.8                  [Expert]................ 2 Tones

[Tone 1]......202Hz (Low Tone) = 0 - 5.0       [Tone 2]....710Hz (High Tone) = 4.8 - 99

2.        [Sensitivity].......... 86                                   [Expert]    TX.......... 2

Set sensitivity according to ground conditions and local interference levels, ideally it should be set high enough to cause the machine to become erratic, then back off until stable, if you have to reduce the sens to 80 or below, then it's best to reduce the TX to 2, then increase the sens to suit.

3.        [Frequency].............. 17.606                      [Expert]........ Frequency Shift

This program was devised to be used exclusively at 18 Khz, but can be set to 12 Khz if you have problems identifying iron.

4.        [Iron Volume]............... 3   (or personal choice.)

Iron Volume can be set to 0 this will eliminate the "Low Tones" without loss of  performance.
5.        [Reactivity]................ 3                                 [Expert].......... Silencer -1

( Reactivity on 3 and silencer on -1 will give the best target separation on sites with high iron contamination )

6.        [Audio Response]...... 4                                 [Expert]........ Audio  Overload 1

Reducing audio response to 3 will give better definition of the depth of a target, also reduce Audio R if a high setting distorts the audio.

7.        [Notch]............ 00-00                                     [Expert].............  Notch Setup

I wouldn't be tempted to use the notch on ancient sites, as you risk eliminating good targets.

8.        [Ground Balance]. Pumping         [Ground Notch].............. 87 - 90

If the machine starts to chatter, reset the GB by pumping the coil again over a "clean" piece of ground, If you cannot get the machine to settle try using manual mode, get the ground reading by pumping the coil, then add 4 digits, enter this figure into the machine in manual mode
Don't forget when turning the machine on to have the shaft extended and the coil well away from the ground or any metal object, when first switched on the coil is calibrating, the light will give 20 long successive flashes, keep holding the coil in the horizontal position until the coil light settles down to one flash every second, you can then lower the coil to the ground.
