HOW TO PRACTICE AND FIND!
Two friends out on terrain: On the left is Nicolas, a professional prospector with his Deepers, who spends all his free time treasure hunting. Having done his research, he reckons that this is a good spot to search. On the right is Oliver with his VLF. He is not having much luck, and as the day progresses the Pulse Induction Deepers shows it true worth.
Nicolas comments: �Research shows that this is roughly the spot in 1825 where a skirmish between the army and a group of gorilla freedom fighters took place. Having robbed a bank two days distant from here on horse back. The haul included, 240 gold coins and a sack full of silver coins. Unseen and under fire, they proceeded to bury the loot, hoping to recover it later on. Legend has it, because there were no rocks, big trees or apparent markings, they were unable to recover the loot�.
Once metal detectors appeared on the market, (BFO VLF-TR-IB) opportunities for new discoveries were provided in places like this. But for a while no one has found anything new on this site. Even modern day VLF machines do not penetrate the soil to any great depth. So this was an excellent site to test out the latest Deepers Pulse Induction model due to the mineral content of the soil.
The adjustments: first you should adjust your detector to the most sensitivity possible for the terrain. I work with the sensitivity knob at maximum (maximum sensitivity and depth with Deepers), the rejection system indicates any non-desirable ferrous target (trash) up to 30 to 40 centimeters in depth, which saves me the effort of digging holes for nothing.
The swing
To investigate a terrain without losing anything you do the following. The detector head must remain parallel to the ground at about 5 to 10 cm. To swing at 2 feet speed per second. Above all, do not lift it at the end of the back and forth movement. After every swing, advance 50cm more or less. Nothing will get away from you this way. From time to time, I suggest you adjust the threshold to always obtain a slight sound and this way be able to perform a better search of the terrain. Even small pieces of metal, fairly deep, will be signaled with a strong sound or threshold blip. It is best to work with headphones, as these will help you recognize easily, any faint, deep, target signals.
Important: If you hear an echo it is a good sign and you should go over the same place slowly so as to determine if it is a good target or if it is just a mineralized rock, for example. You can switch between sound frequencies so you can analyze the sound better and do the same operation with a 90 degree angle, since some times targets are easier to detect one way than another. To pinpoint a target you have found, lift the detector head up slightly, retune the threshold, till you get a threshold tone you are comfortable with.
Lowering the detecting head, the target will respond with an increasingly louder sound. To combat this and assist pinpointing this is the basic procedure as follows. Move the detector head to and fro over the target, slowly lowering the coil, at the same time turn the threshold-tuning knob in an anticlockwise direction. This has the effect of detuning, which in turn reduces the arc of the detector head as it passes over the target. This is till the detector head is hardly moving at all and you still have the target sound in your headphones. At this point the detector head is practically touching the soil. This means the target is now directly under the coil. Practicing this technique with pre buried coins etc will enable you to quickly become expert at pinpointing targets.
The reward: After two hours of searching and digging over twenty holes, Nicolas recovered a hand full of lead bullets, some bronze (or copper) cartridges and at last the find: a beautiful gold coin from 1820 that his Deepers was able to find in a small hole and at only 28cm. deep. Nicolas said �In conclusion, this place is promising, because VLF detectors, due to the mineralization of the ground, have not been able to find anything deeper than 10cm�, (as Oliver found out with his VLF detector). The lead bullets are the proof that some possible military activity had taken place in that area. So, with a beer in hand at a nearby town, Oliver promised to return to the spot� this time with the latest Deepers model.
