- Page 2 ASSEMBLING YOUR DETECTOR 1. On the lower rod assembly, remove the mounting screw and thumb nut from the rod tip. 2. Insert the rod tip between the mounting ears of the search coil and align the holes of the rod tip and washers with those of the mounting ears. 3.
- Page 3 ASSEMBLING YOUR DETECTOR Your detector is standardly equipped with 9X9" and 12X12" new SEF PRO coils. These coils have better sensitivity and depth, better pin-pointing, keep perfect balance even in high temperature range. For getting acquainted with the detector’s operation we recommend you at first use the smaller sized 9X9"...
- Page 4 AUTO MODE OF OPERATION First we’ll introduce the easiest mode of operation of the detector. Further in the instructions we’ll call it AUTO mode. The important thing for this mode is that there would not be necessary to make manual ground adjustments to the different ground conditions.
- Page 5 AUTO MODE OF OPERATION IMPORTANT NOTE: When operating on very heavy and wet grounds, especially if using the bigger sized coils (12x12 inches) while passing the coil over an open hole in the ground, even if there is no metal in it, is possible to hear false signal, as if in the hole there was a metal target.
- Page 6 MANUAL MODE OF OPERATION The AUTO mode of operation is the easiest one, but it does not give you the best performance as sensitivity and depth of the detector. In the chapter below we’ll introduce the Manual mode of operation. This mode of operation is recommended for very experienced detector operators.
- Page 7 MANUAL MODE OF OPERATION adjust control the threshold tone won’t change while lowering the coil to the ground. At this point the detector is balanced for the area and ready to hunt. If you rotate the GND adjust control further clockwise, you’ll pass this point of balance.
- Page 8 MANUAL MODE OF OPERATION especially for smaller targets, after finding the exact ground balance point they rotate slightly clockwise the GND adjust control until they receive an increase of the threshold volume when raising the coil. This is a difficult way of operation, because it is possible to appear false signals caused by the curved ground balance.
- Page 9 DISCRIMINATION The disc control is enabled when you switch the all metal/disc. to the disc. position .The fully counterclockwise position is marked in red - nugget. In this position you won’t have any audio discrimination of metallic objects. You should know, that in heavily mineralized ground tiny pieces of gold can sometimes look like iron to the metal detector, and small iron pieces can look like gold.
- Page 10 NUGGET HUNTING The easiest mode of operation for nugget hunting is the Auto mode (see the AUTO MODE of operation chapter). Have in mind that the disc. control should be in the nugget red zone(Figure 7). In this position, as in the AMD zone you won’t have audio discrimination of the metallic objects in the ground.
- Page 11 BEACH HUNTING For beach hunting we recommend the operation of the detector in its AUTO mode of operation. Lets start with the beach hunting on normal dry beaches. These beaches are easiest for searching, and allow the highest increase of the sensitivity level, even switching to high of the high/low switch. Of course, if there are no strong electromagnetic fields nearby.
- Page 12 CONTROLS The sens control is often thought of as a depth control and it is, but it can also be used to make the detector more stable if interference caused by ground mineralization or electrical fields are experienced. The sens control works in conjunction with the adjustments of the high/low switch.
- Page 13 FALSE SIGNALS AND SOLUTIONS A false signal occurs when something sounds like a good target, but it is not. These signals are produced by undesirable or discriminated targets like large pieces of iron, hot rocks or by electrical pulse-type electromagnetic interference.
- Page 14 SEARCHCOILS Your detector is equipped with the latest generation NEW SEF searchcoils (symmetrical electromagnetic field coils). The Standard SEF coils are the best performance coils. Compared to the Double D coils they have better ground balance, more stable operation, better depth of penetration, better pinpointing, more accurate target identification.
- Page 15 BATTERIES Your detector is standardly powered by 4 Ni-MH batteries, size AA (R6),1800 mAh, which allow you to use the detector for 20-30 hours. The time of use depends on how many signals your detector will locate and process and whether you use headphones. The use of headphones will increase the time of battery use.

- Page 17 MAINTENANCE Your detector is a high quality electronic instrument. Though ruggedly constructed and designed to withstand the normal treasure hunting demands proper care is essential. Operate your detector as recommended in this instruction manual. Remove the batteries from the detector if you are not going to use it for extended period of time.
- Page 18 AIR TEST RESULTS The table shows you the results of comparative air tests between your detector with the standard 9"X9" searchcoil and other VLF detectors of leading metal detectors manufacturers. Please, note that with the 9"X9" coil your detector significantly exceeds as sensitivity all the other tested detectors.
