Statistics of the discovered currencies and others of the ranges

(Ranges and Detection)

I would like to announce my modest experiment of Holiday maker-prospector of the ranges, through small statistical study concerning the found currencies.

The current coins constitute the great majority of the detected objects. I will not speak here about the others such as keys, penknives, earrings (often in the singular) and possible jewels....

Which are French or foreign, these currencies were lost recently by the tourists. The figures which will follow, correspond to a prospection of summer on a range of the Atlantic, between 1991 and 1997, with apparatuses as different as C-Scope 990B and Clubman, Compass Coinscanner pro and Tesoro Silver Sabre More. That gives a rather good idea of the lucky finds which one can hope for. This prospection is connected rather with the style contest rather than with a more technical detection which can practise the local prospectors the winter. Those know the currents, the parts of ranges where the objects accumulate. Perhaps these statistics will make them smile, but I do not claim to be a specialist in this type of detection (nor of another besides).

For a question of time, it is the summer the only period the year when I have the leisure to practise detection, even if that of the ranges is not more exitante, it offers the merit to get a certain pleasure (to find a currency under the traces of step of another prospector) and to allow me to seldom re-enter bredouille.

I prospect approximately three hour by output, preferably the morning of very good hour, mainly on dry sand, where the holiday makers pile up. But I do not scorn the part of range discovered by the tide, to see with the top of water. This zone is less productive in currencies, but can allow the discovery of objects lost in bathes; chains,
medals....

Over the last six summers, the time spent on sand is approximately 160 hours to find 1780 there currencies which break up as follows:

That is to say a total of 3933,95 Francs. The average value of a part is thus 2 Francs and twenty and one centimes.

That gives a little more than eleven currencies in one hour of prospection for a value of 24,60 francs of the hour (to grow rich, it is preferable to make other thing).

- the currency most met remains the 10 Francs (what is happy) because it corresponds the need of the holiday maker: strong value!!! for a compactness.

- 10 centimes, 1 franc, 20 centimes and 5 centimes form large group.

- the yellow parts are more difficult to locate when they fall (and very difficult to recover when they are detected).

- the part of 1 franc is very current. It makes the happiness of the prospector, and pays the piles.

- That of fifty centimes is in my opinion more difficult to find, because of its size and its composition (all the white parts contain iron and can be stuck to a magnet) from where a certain tendency to be discriminated.

- the 2 francs seems less used or easier to find when it escapes from the pocket. What is even truer pôur the 5 francs than its size condemns not to be inserted immediately.

- Remainder the 20 francs which circulates little and with the same problem of size as the 5 francs.

- the foreign currencies are sympathetic nerves and inform about the frequentation of the range.

One finds also currencies old, they of this century, demonetized and are very often corroded. For oldest, this double tournament of 1619 watch which one went on the range at that time.

By looking at my cards, I noticed disparities according to the years and tried to find the reasons of them. I found some found four principal:

1 / Time : Detection on range the summer makes it possible to find objects lost recently. It is a detection of proximity in time. Multitude of the holiday makers the day before or before prospection day before depends the number of objects to be found. And it is easy to check that after one day of rain the number of discoveries is quite lower. The weather thus influences directly the potential of lost objects.

2 / method and the motivation : A rational method of squaring systematic is definitely preferable with a random ambulation. In the same way a constant attention will be more advantageous than the torpor of the early morning, but there, I do not learn anything with anybody...

3 / competition : It is more sévére year by year, and I realize there by crossing the caracteristic traces of step of the night prospectors. But the range is large, with each one to improve its technique...

4 / apparatuses : I put this reason in last position, because if all the apparatuses are not inevitably powerful, it is not them which make the difference. I know a prospector using an apparatus bought 500 Francs and which finds as many currencies as me (but I am not a reference.). On the other hand I found that certain models parraissent me more suited than others. The power is not of primary importance (considering the majority of the parts are under a few centimetres of sand only), but stability, a good correction of the ground effect positive close to water, a good surface of cover of the disc seem more interesting to me. But there, with you to make the choice.

Veiled, they are my observations after a few hours of prospection on the range. Make know to me your opinions or experiments of this type of detection if you practised it or if you wish to do it.
