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 doneĀ  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 theĀ  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.
