WHITE'S
 SPECTRUM * EAGLE
  DEEP SEEKING V.L.F.
MOTION DISCRIMINATOR
If you are an old school treasure hunter, but refuse to compromise on depth you better not miss this solid gold opportunity!

It is a V.L.F.  metal detector which operates at 6.59 KHz:  This exact frequency was chosen simply because its power band is centered within the target viewing SPECTRUM, giving it power-enough to locate low conductivity targets (nickels, gold jewelry), but also able to respond to deep copper and silver targets which are seen by detectors on the opposite end of the SPECTRUM.

This is a Phase Delay Discriminator: This is the state of the art technology which is often called "Motion Discrimination." It has a digital processor that is both efficient and has a very quick recovery timing for effective hunting in trashy areas.


Target Signature Number Assignment: The Eagle series was the first detector to give users the target signature a 'number assignment' for enhanced target definition. This was perfected by Whites simply because many hunters missed the subtle changes in their analog meter's needle position . .  which they used for more accurate target ID.
Well, this V.D.I Number Assignment is like High Definition Target Identification!

  Factory Pre-Program Mode Choices:

4. PROSPECTING
5. USER STORAGE PROGRAM #1
6. USER STORAGE PROGRAM #2

Basic Adjustments

1. Volume
2. Threshold Level 
3. Audio Tone Level
4. Audio Discrimination (Off - On)
5. Silent Search Audio
6. Mixed Mode Audio
7. AC (ACTION) Sensitivity (Sensitivity Level while hunting with coil in motion)
8. DC  (DEAD CENTER) Pin-Point Sensitivity.
9. Meter Back-light  (Not Working)    (The meter back-light is not working.)

Pro Tuning Options

AUDIO SELECTION
1.  S.A.T.     (Self Adjusted Threshold)  ON - OFF
2.  S.A.T. SPEED   (Slow or Fast Tune Speed)     beneficial for prospecting in black sand streaks
3.  TONE ID    On - OFF
4.  V.C.O.  (voltage controlled oscillation)  Rolling, changing pitch audio . . . great for pinpointing!
5.  ABSOLUTE VALUE  for pairing with aftermarket coils for target ID accuracy
6.  MODULATION  ON - OFF   (when ON the distant targets are more faint, when OFF all targets sound alike)
 Turned "On" is deeper if you can hear OK)

G.E.B. and TRACKING OPTIONS

1. AUTOTRAC   ON - OFF   (Computer monitors coil sensitivity and adjusts according to changing mineral conditions  for max depth
2.  AUTOTRAC VIEW   (Watch autotrac's activity, to see if speed should be adjusted)
3.  AUTOTRAC SPEED ADJUST
4.  AUTOTRAC OFFSET  Detector can have speed slowed to correct "after-the-fact" in a prospecting "Follow the Pay Streak" function. (this is for following black sand streaks)        
5.  MANUAL GROUND BALANCE    (prospectors can choose slightly positive for getting tiny sub-grain gold) 

DISCRIMINATION PROGRAMMING

1. EDIT NOTCH WINDOWS  (To open or close windows you select) A target window that is closed will reject any target seen behind that notch window.
In the upper quadrant there are +95 windows
In the lower quadrant there are  - 96 windows
2. BLOCK EDITING   For rapid editing  (great for searching for a known target quickly close all but wanted window)
3. LEARN TO ACCEPT
4. LEARN TO REJECT    These are for opening or closing a window waving a sample
5. RECOVERY SPEED   Adjust the recovery speed (Faster or Slower) based on coil size.
6. BOTTLE CAP REJECT    Makes rusted trash items sound nasty

DISPLAY ADJUSTMENTS

1. Visual Display  You can turn ON or OFF the target number value and the target ID labels.
2. V.D.I. Sensitivity  Under sever electrical or radio interference areas, a detector's system can become unstable which could also make the meter unstable.
3. Ground ID (D.C. Phase) This can be used both the read target depth when pinpointing, but also to measure a reflective ground signature.  This can be useful to test for a bad coil.

SPECTRUM OPTIONS

1. GRAPH ACCUMULATE  repeated passes over any target will sample and accumulate the data shifting onto display.
Graph accumulate is perfect in dealing with iron stained ground which creates a tell-tail signature smear. (rusty trash)
2. GRAPH AVERAGING does not accumulate signature data but instead displays the best data average.
3. FADE RATE    Speed at which the screen display will refresh after displaying target information.

SIGNAL CONTROL

1. HIGH TRANSMIT POWER  For normal hunt conditions where your signal is not bleeding another hunter
2. LOW TRANSMIT POWER  For group hunts where you wish to maintain friends!
3. FREQUENCY SHIFT   Where you have another detector or radio bleeding onto your detector (Find a clean channel)
4. PRE AMP GAIN   The most misunderstood! The detectors ears. Buy nature metal detectors hear to much! The range goes from 1 to 15 and the factory default is "1" and very often that is too high!

Target label assignment: This is a interpretation of the number assignment to words such as "Quarter" "Half" "Dollar"

Push button ground cancel: Ground cancel is simply tuning the search coil (antenna) so that it is not so sensitive that it reads its own reflection from the ground.
The other side of ground cancel, is making sure the coil isn't badly "de-tuned" causing it to not see far enough into the ground.
This is called 'ground balance' because you are finding that perfect balance between coil sensitivity and soil conditions.

Ground Balance Alert:  This Detector will warn operator if ground is not suitable for accurate ground balance (metal present) and can also alert user if the mineral presence is extremely low.

Auto Trac: Once the detector coil is ground balanced (erasing the ground's signature), an automatic tracking function monitors and adjusts the coil for changing ground conditions. The beach hunter or prospector understands, where on rare occasion, this feature could tune out small gold chains or tiny gold picker nuggets . . . . so, Auto Trac can be fixed in a locked position!

Coil Overload: If you are ground canceling over a hidden metal object, the detector alarms you to look for a better spot to tune.
