Description

About Fisher Research Labs CZ-21 Quicksilver

Your CZ-21 QuickSilver is an all-purpose metal detector engineered for land, beach, salt and fresh-water treasure hunters.

Leak-proof
Submersible to 250 feet.

3-Tone Target-ID
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.

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.

Two Search Modes
A silent running, slow motion Target-ID Mode and a hot, Auto-Tune Mode for All Metal searching.

V.C.O. No-Motion Pinpointing
Tap the pinpoint button and the audio tone increases in pitch and volume as the center of the coil approaches the target.

Big-Target Alert
The CZ-21 circuits may overload on large, shallow targets. A distinctive bell tone immediately warns you that the target is too large to identify.

Faint-Target Audio Boost
As you increase the volume level past “5”, strong target sounds remain at a fixed volume while faint, deep-target sounds continue to get louder.

Quick Manual Ground Balance
Tap 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 conditions.

Separately Sealed Battery Compartment
Protects the electronics from accidental flooding.

Searchcoils
The CZ-21 comes with 8″ coil. All coils are permanently attached.

Balanced, Comfortable and hip-mountable
Cushioned armrest, soft foam grip and a control housing that slips off the handle and onto your belt.

Salt Water Compensation
Salt water is electrically conductive and therefore induces a strong signal in the searchcoil. Unlike most other metal detectors, the CZ-21 uses Fourier Domain signal analysis to cancel the salt water signal. Under most conditions you will not experience any false signals from salt water. When working in the surf zone at high sensitivity settings you may hear an occasional “whisper” which is easily ignored.

Easy-to-Use
Just pick it up, set the control on the red circles and start searching in a “coins-only” mode. Or for maximum performance, adjust the controls for your own specific situation.
