Looking at the Ground channels most of the
ground and some of the smaller ferrous items will
no longer be displayed when comparing them with
the Delay channels.
On the metal classication pictures stronger
signals which generate a conductivity reading will
produce mainly a single colour dot corresponding
to the delay reading on the display of the DEEPMAX
Z2. Neutral ground will cause a purple indication.
Dierent nearby metal objects lying in close pro-
ximity will give dierent colours in most cases for
better selection. See table of metal classication
indications:

The LORENZ DEEPMAX Z2 is practically service free.
The electronics control box and the other compo-
nents should always be kept clean and dry. This is
particularly important for the plugs and jackets,
which should never be stored when being wet. The
electronics control box is water and dust protected
but it should be avoided to immerse the unit in water.
All search coils available for the LORENZ DEEPMAX Z2
are waterproof up to the connector which is not wa-
ter proof. All the connectors should be kept dry and
disconnected from the Z2 unit when not in use.
The LORENZ DEEPMAX Z2 is ruggedly designed. All
necessary electronics components are placed on
two printed circuit boards. The main circuit board is
covered with a special plastic to protect it from rapid
temperature changes and humidity.
Dierent components like the front panel, circuit
boards and connectors can easily be exchanged if
necessary.
FIRWARE UPDATE
When planning to update your Z2 with a new rm-
ware version please refer as follows:
Turn OFF the Z2 and connect the optional USB
cable to the Z2 and the computer.
Push simultaneously in the order 1 ZERO, 2
MENU, and 3 OFF to turn on the Z2 and to start the
data transfer function which will be indicated with a
single USB icon coming on.
Select a new rmware version provided on our
website at Service and proceed as described in the
instructions on our website.
It is strongly recommended to have charged
batteries and not to disconnect anything while data
transfer is in progress.
