The LORENZ PULSE 5 is one of the newest

developements in the field of Pulse-Induction Metal

Detectors. It is probably the most sensitive and

stayable metal detecting device of it's kind presently

available. The LORENZ PULSE 5 is the result of many

years of research and developement. A lot of efforts

have been put into making this new product and

especially in the new metal classification facility

offered with the LORENZ PULSE 5.

The Pulse - Induction principle is specially suitable

for searching at depth. The performance of this

electronic device is unaffected by salt water, most

types of soil or temperature changes. The LORENZ

PULSE 5 is therefore a reliable tool to locate metal

objects at great depths even under the worst

environmental conditions.

The LORENZ PULSE 5 is a high quality specialist

Detector and it is designed to be used with both,

small or large coils. Large coils offer extreme depth

capabilities for big metal objects because of the

strong and deep going magnetic field produced.

Small coils are preferably used while searching for

small objects like single coins or Gold nuggets.

This model offers a great range on non-ferrous

metal objects in general. A very simple operation

is guaranteed by four controls of which only one

reset button will be necessary to operate during

work. At the same time this detector model offers

a number of features which are new for a Pulse-

Induction Metal Detector. Quality electronics and

very special designed electronic - circuitry produce

benefits in terms of easy of use as well as sensitivity.

The LORENZ PULSE 5 gives a visual indication on

the meter for every metal being located. This

conductivity meter reading helps to classify metal

objects. The target classification circuitry is only

weakly  affected by the size of a metal object and

therefore identifies small coins as well as large

pieces of metal. The Detector also emits an audible

sound by way of either a speaker or headphones.

Detection depths achieved (in air tests) are almost

the same in the ground and therefore considerably

higher than those possible with standard Pulse-

Induction or Sinewave VLF - TR Detectors.

The LORENZ PULSE 4 & 5 Metal Detectors are

recognised as representing the highest quality and

newest developements in professional metal

detecting equipment.

We as a manufacturing firm always try to keep the

highest standard on our products, therefore

alternations of the design, specifications as well as

the availability subject to change without notice.

1. Safety information

For reasons of safety it is advisible to read this

operating manual first before turning the Lorenz

Pulse 5 on. Special attention should be paid to the

following notes.

Check out, if the plug-in type recharger supplied

with the Lorenz Pulse 5 fits with the AC mains of

your country. The AC plug of the recharger is inter-

changeable and therefore can be used at any

countries mains. See chapter 7 for more detailed

information. The supplied recharger will work at

AC voltages of 90 V-264 V (see lable).

Damaged connecting cables or searchcoils should

no longer be used, because of possible electrical

shock.

To avoid short circuits, wrong polarity or electrical

shock only spareparts and accessories offered by the

manufacturer of the LORENZ PULSE 5 should be

used.

When digging for metal objects war material could

also be found. Precautions should be taken in advance

especially when big objects have been located.

Special kinds of mines could be triggered by the

strong magnetic field produced by the searchcoil.

Please understand that we as the manufacturer of

the LORENZ PULSE 5 can't be made liable for any

kind of damage caused by or in conjunction with our

products.
