Detailed instructions for use are in the User's Guide.
[. . . ] They are designed with lasting quality in mind, high technology, and above all, value for money. The only way to realise this value is to carefully study and understand this instruction manual. You will then be able to obtain all of the advantages designed into your detector. It is also strongly recommended that you experiment with the detector's operation in air, with various test samples, in order to learn to identify and understand the detector's capabilities and responses. [. . . ] Where there is no ground effect or outside interference the SENSITIVITY control can be operated at higher levels. But when the signal becomes unsteady or erratic, the Sensitivity level should be reduced to obtain a clear, steady tuning threshold. Only when the tuning is constant and steady will the detector operate at the best optimum depth penetration.

Ground Exclude
The G2 GROUND EXCLUDE selling is designed to cope with even the most
severely mineralised sites. This setting is marked in red as it is most
frequently needed.
However, you may need to select either G1 or G3 under the following
circumstances:
Select G2
Lower the search head to the ground from approximately 50cm away.
If the meter needle remains central and the threshold tone stable then search
in G2 after selecting the desired automatic discrimination.
If, when the search head is lowered, an increase in sound is heard and the
needle deflects to the right, then select G1.
If alternatively, a decrease in sound is experienced and a left deflection of the
needle then change to G3.
It is as easy as that.
When operated, this control acts as a memory re-tune bullon as described
under Tuning (pA). It also indicates which Meter Console mode is engaged
by lighting a red LED over any mode which is on.
Auto Tune maintains the threshold set by the tune control and is particularly
useful in the first 30 minutes of searching whilst the machine is warming up
or in adverse ground cOAditions such as the beach.

Meter/Audio Discriminate
The levels of Discrimination or Rejection are identical in both modes Meter and Audio (Discrimination c;an be defined as the ability to give a different type of signal for ferrous junk or worthless objects than the signal given by a non ferrous object). Both these Discriminate Modes are set at such a level, so that depth penetration to coins etc. is good, and discrimination against most iron and silver foil is achieved. A precise level of discrimination is selected to give maximum discrimination, without affecting sensitivity to coins, etc. Pull tabs, large silver foil, or large iron will not be rejected, because the levels of discrimination required to reject these also reduce the depth penetration to certain non-ferrous metals and thin section objects. It is not possible to reject a valuable object with the PROMET 3's AUDIO or METER DISCRIMINATION Modes, if the object is in range. Each time a signal is heard, listen for any peculiar characteristics it may have, determine over how large an area you get a detector signal, and try to "outline" the object before you dig. Listen for the sharpness or dullness of the signals and determine the magnitude of strength of the signal. After digging up the object, compare the object size, shape, depth and position in the grouno with signal information you received before digging. After careful analysis of many digs, you will learn to "read" the hidden target before digging.

The Importance of the Right Approach
Treasure hunting can be a profitable and rewarding hobby, if approached in a patient and diligent manner. Time spent researching to locate a worthwhile site for a search can be time wasted if your search is hasty and erratic. To achieve maximum results it is important then, to decide on your approach to any particular site in advance of the actual search. Tactics will be decided by the type of site - it is more profitable to scan a small area thoroughly, than to conduct a haphazard search of the total site. However, when the site is too far away for you to make several return visits a plan should be adopted which gives maximum site coverage, at the same time as indicating the most likely area for detailed search. Your detector alone is not a guarantee of successful treasure hunting. Any detector needs an operator and for the best results the operator needs the right approach, attitude and technique. Too many beginners neglect the importance of pre-planning and research before using their detector in the field, and patience and technique during the actual search. [. . . ] Usually this point centres around the quantity of coins in a hoard, or whether the find is in a container. Obviously, if there are a hundred or so coins in a pot, they were almost certainly deliberately concealed. If, however, there are only one or two coins, it is more likely that they were lost accidentally. If the objects are declared Treasure Trove, the finder has no need to worry, for he is rewarded with a cash settlement to the full market value of the find. [. . . ]
