The Gold Jewelry Numbers inland searching


This is an accurate video when it comes to digging gold jewelry inland as opposed to beach hunting. One comment to this video question the need to dig all targets when hunting gold jewelry. I will just tell the guy who made the comment to just look at the AT Pro VDI chart. Notice that there is no single VDI number or close by numbers that can accurately indicate gold jewelry. Gold jewelry values shows all over the VDI chart. That is the reason you have to dig all signals in an area that is likely to have gold jewelry like parks. Hunting ocean beaches is a completely different story. There is less junk on an ocean beach and junk on an ocean beach means different things on the lower beach and upper beach. Light junk (pop tops, tin cans, fishing lures) on the lower beach (wet and in water) means you are not going to find jewelry at that spot. Heavy junk like lead weights, nails, old corroded coins indicate you are likely to find heavy gold and silver jewelry. On the upper beach light junk like pull tabs, foil and tin cans indicate people activity and thus likely that you will find gold jewelry lost from the sun bather. So on inland hunts, you have little choice but to dig all signals above 35 on the AT Pro to be sure not to miss the gold. You may dig a hundred or more junk finds before you strike gold.

Compare Garrett 9×12″ Concentric Coil with Stock 8.5×11″ DD

Ok, just viewed an air test of the Garrett 9×12″ concentric coil vs the Garrett Stock 8.5 x 11″ Double D coil. He used the two coils on the AT Max. The test was done  on an individual’s metal detecting channel on Youtube. Full disclosure requires me to let you know that I like most of his videos and being well filmed and an accurate representation of the metal detecting hobby with little or no hype.

Now here is where I fault his air test. The air test shows the concentric coil delivering better results on deep targets. Well that is a given due to the different coil designs. The DD coil will deliver a full 11″ swath at max depth whereas the concentric coil (using a cone pattern) will deliver only an inch or so swath at maximum depth. So now lets figure in the hunting time looking for deep objects. It is 11 to 1 ration in favor of the Double D coil. So a 2 hour hunt of a specific area with the  Double D coil will turn into to a 22 hour hunt using the concentric coil.

On the upper beach or volley ball court or areas where the targets are only 2″ deep, then the coils are basically equal. On a search for deep coins or jewelry, you could not possibly consider using a concentric coil.


Garrett Pro Pointer AT refresher notes

We sometimes just think the pin pointer a simple device. In fact we should remember the Garrett Pro Pointer AT has more than just an off and on switch. Watch this video again and see how you can apply the features to speed up your target recovery time.  One of the things that I use the most is using the pin pointer to determine the size of the object by tracing the outline of the target on the ground. This works for your targets that are 2-4 inches deep.

Hunting Trashy Parks with the Garrett AT Pro

The reason parks are never hunted out in terms of old coins is that the average metal detectorists does not swing slow, does not use small coil, does not clean out all the junk in the hole, and does not dig deep deep targets. When the average metal detectorists hunt in a real trashy area, they find the display jumping around like crazy as well as being overwhelmed by all the many tones.

Set your AT Pro set on Pro Zero (other detectors in the all metal mode),  iron audio on, notch out 65 and below. Swings slowly to tease out the high tones. Do not rely on the display numbers. Notching out 65 and below will eliminate the display and sounds of  all the pull tabs and foil and other undesirable junk. We are looking for coins, not gold rings.

You should dig out all the trash out of the hole to eventually get just the high tone target.

If you are getting a high tone, there is a high tone target mixed in with junk. You cannot go by the display, since it jumps all over the place. The same goes for the tones, they jump all over the place. This is why you notch out 65 and below, to eliminate some of the distracting noise. If you hear a high tone, there is a high tone target in the hole. Once you think you have removed all the junk, swing your detector back over the hole to see if you are still getting a high tone. A lot of coins are found at the 4-6″ level, but the deeper signals increase your chance of finding a coin since the average park hunter does not dig that deep or clean out the junk. Notice that when you clean out the junk and pass your detector coil back over the hole, the high tone will be a lot crisper. When checking the depth of a target in a hole with junk or other targets, they can throw off the depth indication reading in the display. The AT Pro depth indicator tends to be more accurate on a single target. I rarely look at the depth display, but listen to the relative volume of the high tone.

Go to the park on the weekend and just observer where the people are located. In my park along the river, I see people playing volleyball, families having their picnic lunches at the concrete tables. The most desirable tables are along the river under the trees. The people are wading in the shallow part of the river near the rocky shoals close to the river bank. There is one trail up river where the majority of the fishing takes place and beside that a youth soccer field that is in use on the weekend virtually all day. So these are the areas of the park that I hunt once or twice each week since it is within 5 minutes of my home and I need to take a break from writing and do some swinging.
