What do caches sound like?

[qtrs-xcite-me]

It has occurred to me that if one is to find a significant treasure it is likely to be a cache. If you have found a cache, how did it sound on your detector? In other words do they typically sound like iron or like silver? What should new detectorists be on the look out for to avoid bypassing a cache?

The reason I ask, is when I was detecting a city park playground area yesterday, I kept getting what I would call a quarter/silver high tone on my detector with a numerical display indicating a likely clad quarter but with a depth in excess of 10 inches with my sensitivity set at 40%. When I would dig down about 5", my pinpointer would go nuts with a really loud signal like I was right on top of a find, but giving the same signal wherever I pointed in the hole. Digging down about 10 " and I still did not find the target. On at least one hole, I did feel hard metal with my trowel even deeper than I had dug. The targets seemed to be oriented in a line and I suspect were part of a deeply buried pipeline or some such thing. Since I was in a park, I did not want to pursue these, but it got me to wondering about cache signals.

Thanks for any input.

Depends on the detector used.

You can also depth probe the area with long metal rods, a technique used by archeologist.
I have found that the best probes are made from the rods found in old index card files and file cabinets.

Every signal I've dug that sounds like a quarter but is way deeper than it should be has turned out to be an aluminum can. How they get so deep sometimes, I have no idea.

Depends on what it is in. IF its's in an Iron Box - Iron
If in a Old Jar with a Cap - Tin or whatever Metal the lid is
If the jar is Laying on it's Side , Depending how you swing over it, - Trash !
If in a Tin Can or Tin Box - Tin
If the Tin is very Old, Probably Bad Ground. At the Tin may have rotted away.
If in a Brass or Copper Pipe, - a Brass or Copper Pipe
If just a Pile of coins , - a Very scattered Signal that won't Lock on

Unless someone Asks for Help & Absolutely Knows What it is In, If you want to find a Cache, Consider every Signal no matter shape or Size ! From Tiny coin size to Overload .
& look in every Pipe or Box Found.


My only Cache was in an Old Tobacco Tin
I Dug a Walker and Left. a lot of Nulls there.
Next Hunt, a week later, I Hit another coin at the same Spot
& Stayed on my Knees Digging the Trash ETC

all that was left of the Tin was a Screwed up signal

Though unknown Brand, All that was Left was
Rusty Ground & The rims

These were 5-8 inches deep. Except the can in the lower left. The one was 10 inches deep. All sounded like great targets, mid 90's.

Very Deep Coins on My Explorer are Wide & Soft.
coins near the surface are tiny But Loud

I found Many Walking Liberty Halves thinking I was digging another Soda/Beer Can !

My Very deep 1877 Trade Dollar on my Sovereign Sounded like a deep Quarter or dime

after getting frustrated digging can after Can, My '76 Ike Dollar Sounded like just another Crushed can under the grass on my explorer. and was Pure Shock when I First laye'd Eyes on it.

I've had Gold come up as a Nail all the way up to a Quarter !
a tiny 18k Engagement ring a Nail.
a Very Large 10K Class ring a Quarter

DIG !
