About Your - Fisher CZ-20 Quicksilver Operating Manual

ABOUT YOUR DETECTOR
Your CZ-20 QuickSilver is truly an all-purpose metal detector
engineered for land, beach, salt and fresh-water treasure
hunters. Here are some important built-in features:
1. Leakproof: Submersible to 250 feet, headphones
and all.
2. 3-Tone Target I.D.: A low tone for iron; a mid-tone
for pull tabs, foil and most gold rings; and a high
tone for U.S. coins, silver rings and some gold rings.
3. Visual Target Response: Two bright, red LED's flash
over targets, varying in intensity according to
target signal strength.
4. Depth: Patented Fourier domain signal analysis.
Two deep-seeking, ground-compensating VLF
signals (one at 5 KHz and one at 15 KHz) provide
twice as much target information for accurate
analysis and identification.
5. Two Search Modes: A silent-running, slow-motion
target-I.D. mode and a hot, wide-scan autotune
mode for all-metal searching.
6. VCO No-Motion Pinpointing: Just push the
pinpoint button and the signal tone increases in
pitch and volume as the center of the coil
approaches the target.
7. Big-Target Alert: Ordinary detector circuits
overload on large, shallow targets, identifying them
as good targets. But not the CZ-20. A distinctive bell
tone immediately warns you that the target is too
large to identify.
8. Faint-Target Audio Boost: The lower range of the
volume control is like any other that you've used.
But as you increase it above mid-range, strong
target sounds remain at a fixed volume while faint,
deep-target sounds continue to get louder.
9. Pushbutton Ground Balance: Just push the
pinpoint button and lower the coil to the ground.
Then set the ground control just below the audio
tone and you are precisely tuned for on-site
