GENERAL DESCRIPTION

The Nexus Coronado is an Analogue Induction Balance (IB) metal detector
that operates in the audio frequency range and it is designed for use on
Inland Sites.
The Nexus Coronado can also be used in salt-water contaminated
conditions, such as tidal beaches.
It may be used in either of the few basic modes of operation; All Metal,
Discrimination, Voltage Controlled Oscillator (VCO) or VCO plus
Discrimination.
The Nexus Coronado is designed to be a general-purpose metal detector,
capable of finding both small and large targets at extreme depths.
The standard coil supplied is the dual 6" Coronado Silver search coil tuned
at 8.5 kHz +/-0.5 and it is ideal for general searching operations. There are
number of accessory search coils available designed for optimum
performance when searching for the tiniest targets in difficult conditions or
larger objects and hoards.
To obtain the best results with the Nexus Coronado, as with all metal
detectors, it is essential to understand the settings and operation of the
detector. Considerable experience in metal detecting is not essential when
using the Nexus Coronado and it is relatively easy for beginners in the
hobby to learn to use it. However all users will need to practice and
experiment in order to obtain the best possible results on any particular
site. All sites and soils are different and settings that will give good results
on one site may be less successful if used elsewhere. The Nexus
Coronado is designed to detect very deep targets and operates near to the
limits of what is achievable with induction balance.
Each Nexus is hand-built so that there may be minor cosmetic differences
between individual units. Each coil is tuned to a slightly different frequency
within the design range, to minimize interference from other Nexus
detectors. Performance values for all Nexus Coronado detectors will be
identical when the same search coils are in use.
