General Description
The Nexus Standard MP is an Analogue Induction Balance (IB) metal
detector that operates in the very low frequency (VLF) range and it is
designed for use on all Inland Sites, Tidal Salt Water Beaches.
The Nexus Standard MP is benefiting from our new Super Dumping
Technology that gives it the ability to effectively suppress by means of
proper balance any kind of mineral material that exist on the ground
surface.
MP stands for Mineral Power.

The Nexus Standard MP currently may be the most efficient IB metal
detector for use in heavy mineral ground conditions and strong magnetite.
It may be used in any of the three basic modes of operation - All-Metal,
Discriminate or Turbo Audio Mode.
The Nexus Standard MP is designed to be an All-purpose metal detector,
capable of finding both small and large targets at extreme depths in normal
soil conditions. It is also designed to work with very high efficiency in all
existing types of mineral soils and magnetite (black sand).
The standard coil supplied is the 10”DD and this is ideal for almost all
searching operations.
There are 3 different search coils currently available for the MP that can be
used as accessory with the Nexus Standard MP.
DD shape search coil range.
- 13"DD at 6 kHz
General search coil designed for higher detection ratio of small, medium
and large targets in all search conditions. It exhibits greater depth than any
other DD search coil in the MP range.
Due to large search area it will find more targets for shorter period of time
compared to smaller search coils.
This search coils is best of all suitable for mineral conditions as its greater
size will result in lower mineral interference and greater depth compared to
the smaller coils in the range.

- 10"DD at 7 kHz
It could be the best general search coil that you’ll ever need. It exhibits
excellent dept and discrimination in all conditions. Very efficient in detecting
small targets at great depth. Very fast in isolating individual targets.
- 7"DD at 8 kHz,
General search coil designed for quick scan of new detecting fields and
areas. Very good for searching narrow spaces, holes and ditches. Best
suited for small and medium targets in contaminated areas.
Each coil is tuned to a slightly different frequency within the design range,
to minimise interference from other Nexus detectors. Performance values
for all Nexus detectors will be identical.
To obtain the best results with the Nexus Standard MP, as with all metal
detectors, it is essential to understand the settings and operation of the
detector.
With the Nexus Standard MP professional users can enjoy the benefits of
the deep seeking Nexus technology, .
As a general rule the best results will always be obtained when the Nexus
Standard MP is properly set in manual mode. Therefore 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 Standard MP is designed to detect the very deepest of targets and
operates near to the limits of what is achievable with induction balance.
Assembly & Preparation
The Nexus Standard MP is supplied boxed and ready for quick assembly
by simply attaching the two lower stem poles to the top one, tightening the
collars and attaching the coil to the lower stem section, using the plastic
bolt and friction washers supplied and tightened by hand so that coil is held
at the correct angle to the stem; the coil cable plug is inserted to the socket
in the control box and then tighten the knurled ring, taking care when
winding the cable around the stem that the cable is not strained.
The centre stem pole is of the same tube diameter as the top one and can
be left off in circumstances where a short stem is needed; it is meant for
use on steep sites, river banks, caves, ditches and similar conditions.
The Nexus Standard MP is supplied with a drop in battery holder that can
be used for all types of AA size batteries, (alkaline or rechargeable); a
charging socket is provided to the battery box for connecting a charger unit.
To insert or change batteries remove any three of the thumb plastic screws
from the base lid of the battery box (the battery box is below the arm cup at

5
the top of the detector stem) and loosen the fourth screw. Turn the cover to
the side. Insert the 10 batteries, in their correct alignments, into the plastic
holder and make sure that all the terminals have a good electrical contact.
Locate the battery holder into the compartment, ensuring the connecting
terminals of the battery holder are in good contact with the two electric
spring loaded terminals behind the recharge socket. Do not over-tighten the
plastic thumb screws when refitting.
If you wish to use headphones (highly recommended) connect your
available set to the 6 mm jack socket on the battery box. The Nexus
Standard MP has an internal loudspeaker so headphones are not
absolutely essential. For any headphones that have a volume control,
ensure that this is set to MAXIMUM and use the Nexus Standard MP
Volume knob on the control box to set the volume level.
Controls
The Nexus Standard MP has eight rotary control knobs and three toggle
switches (two located on the front panel of the control box and one
underneath the control box)
