THE PREZ SEZ Hi all; well here it is, it’s officially fall. We entered the autumnal equinox yesterday, Sept. 22 at 11:44 AM. That is the time of the year when the center of the sun crosses the equator and day and night is of equal length. Hence shorter days and longer nights until December 21, when we again begin adding a minute or so to each day. This is also a time of the year when we need to exercise a little extra caution when metal detecting in or near a wooded area. Beginning early October various hunting seasons open, resulting in people being in the woods that could mistake a detectorist for the game animal he or she is stalking. I strongly urge any of you that might be in or near the woods detecting, to wear at least a “hunter’s orange” cap or vest or both. Don’t forget our Fall Hunt is to be at Boobie and Carolyn’s on October 12 and that we are to bring our own eats and drinks to this event. If you wish to bring a dish or dessert for everyone to share, that is wonderful but not required. Please remember to bring any coins or prizes you wish to donate, to the hunt, with you to the meeting at the Penn Bistro on Thursday, October 2nd. See you all there. Happy hunting, be safe and may God bless.

Water Hunting Season Yes the water hunting season is just about over. It has not been a banner year for those of us that seem to live for only that part of our hobby. I know of some who went on a long 1200 mile trip and came home with only a few trinkets. There were those who made many-many trips to several lakes in Western Pa and came home empty-handed. Yes some of us got a few gold & silver trinkets, but not like years past. My wife and I with another couple went on a four day hunt to several lakes and came home with only a few clad coins. Three of us went on our annual Labor Day excursion and came home with less than $10.00 in clads between all of us. The weather has been damp and cool this summer, the adults have not been in the water but to get wet and than lay on the beach. So I guess it is time to break down the water detectors, clean them up and remove the batteries until next year. 8^( Yes you read it correctly ‘wait till next year” It will be here soon enough

Minutes of the September 2008 Meeting
The September meeting of the BCDC which was held at the Penn Bistro on August the 7th was called to order at 7:15pm by the club President Red Craft.
There were 12 members present.
The minutes of the previous meeting were read by Secretary Harry Niemeyer and approved as read.
Gary Waddell read the Treasurers report, which was approved as read.
Boobie gave a report on the website and the progress being made on developing it. We decided to keep the forum even though there seems to be little use of it at this time.
The hats and a few tees have all been paid for. If you want to order more you can contact Curt or the lady who makes them.
September the 6th Chuck from Treasure time will be visiting here on his way to his hunt in central Pa.
There was a decision on the fall hunt. It will be at Boobies place on October 12th. It will be a brown bag affair, which means bring your own food. Please bring any donations to our next meeting. Donations can be anything you wish to donate. It does not need to be metal detecting related.
We discussed the Christmas party and it will be on our December 4th meeting date. There will be a drawing for gifts. Gifts must be at least $5.00 and no more than $10.00. Everyone including children must supply a gift to get a gift.
My notes say $1.50 for drinks and $13.50 for dinner, these amounts are subject to change. This will be a buffet style dinner. Several ideas for the food were discussed and a veggie medley was mentioned. I am sure the Penn Bistro will have an excellent spread for us.
Ralph Hague won the 50/50 and donated his winnings back to the club.
A motion was made and seconded to close the meeting around 9.00pm
Please bring your fall hunt donations to this months meeting
Will metered detectors find coins deeper than non-metered?
The use of a meter on a detector is no longer any indication of its depth capabilities. When metered machines were the top-of-the-line machines, engineers matched the detectors with the best possible circuitry. With the advent of more cost effective digital signal processing and LCD displays, there are a number of units available that are inexpensive and have meters. While these detectors have acceptable depth, there are plenty of other machines that have better.
The main thing to remember is that a metered machine will give an accurate audio signal on a target much deeper than an accurate meter reading. Air tests are a good indication of the ability of any display-type detector, but once the target is in the ground, there are several variables that may come into play affecting the reading. The most common is the fact that pulltabs and gold rings fall into the same area based on the mixing of alloys. The orientation in the ground can also cause some confusion for the detector. If you choose to get a metered machine, dig any target that gives a good audio signal regardless of the meter reading. You may dig up more trash, but in the long run, you will find more desirable targets.
Is a crystal-controlled detector better than one that is not crystal-controlled?
Most manufacturers use crystal resonators in their machines because of the tight tolerances of the resonator. If the part is listed as 15.7 kHz, all parts will be exactly that frequency. The downside of these super tight tolerances is that the detectors are more likely to crosstalk with each other. In other words, the transmit and receive signals from two or more different machines will start interfering with each other.
Tesoro detectors use an LC or tank circuit to generate operating frequency. A capacitor and an inductor are paired together and create a naturally occurring efficient frequency. Variation in the capacitor and inductor cause slight variations in the operating frequency, which reduces the likelihood of crosstalk with other Tesoro machines. The variation is small enough that it does not affect the performance of the detector.
Are multi-frequency detectors better than single frequency types?
The tank circuit described above generates a sinusoidal or SINE wave form. The SINE wave is efficient to generate and has no harmonics.
Two frequency machines may combine a pair of SINE waves but are more likely to use a square wave. Multi-frequency machines almost always use a square wave or modified square wave. Square waves are rich in harmonics and take more battery power to generate. Harmonics generated by a square wave can be counted as individual frequencies and can be used to give more information as to target type and depth.

This article shows you an
easy way to refine
your scrap gold or old jewelry. Once you finish this process you will end up
with .999 pure gold bullion. This at the current market price is over eight
hundred fifty dollars per ounce. Just follow these few
easy steps any you will learn how to refine
you old gold in to .999 pure
bars of gold
First you need to
get the gold that you want to refine. It could be old rings, necklaces,
earrings, or anything that is made of gold that is no longer wanted. Once you
get the gold it will be tossed into a hot acid bath of something called Aqua
Regia. Aqua Regia is a mix of Nitric acid and Hydrochloric acid, usually in a
volumetric ratio of one to three. Next you would add the gold carefully as to
not splash the acid, remember to always wear gloves, safety glasses and
protective clothing, as you would not want to hurt yourself in the process. The
Aqua Regia is left to sit overnight and the next day.
Then you pour off
the acid. The acid is what contains all your gold. Once you pour off the acid
you will want to collect anything that is left over. Only good metals will not
dissolve so what you have is most likely silver. Rinse the pieces that are not
dissolved, at this point you are also able to recover any gem stones that were
in the jewelry, diamonds etc as the acid does not harm good stones. These can be
sold or reused. Next you must neutralize the nitric acid
which has
partially been done
by heating the acid but is best done by adding Urea/ Uric acid...and yes its
urine and yes urine does work.
But urea fertilizer
is more sanitary, and then we add Sodium Bi Sulfite to precipitate the gold out
of solution. It falls to the bottom as a nasty brown powder and it's not the
nicest form of gold to look at. That is rinsed several times and filtered. Then
after the gold is filtered it then will be heated by a torch. The final result
is a pool of gold once melted. The gold is allowed to cool for a short time and
then tossed into water, once the gold cools down and is not steaming its safe to
pick up and hold. Congratulations you have completed the process and made gold
bullion.
I found this on the internet and have no idea if it works or not. I would add that this may cause some fumes and should be attempted under proper conditions.
