Bogus Residential Coin Hunting Question

[ggossage]

This may be a difficult question to answer...it is for me.

I do a fair amount of hunting in yards. Those of you who hunt yards know you never know what you're going to get when you put your coil on the ground. My question though is for hunting a particular type of yard with activity dating back to let's say the 1880-1890s (typical for my area).

Often when I hunt yards there's a fair amount of newer clad and trash...That's a given in many yards. Now I pose this to you; if you end up in a yard with a fair amount of clad: pennies (memorials and zincolns), nickels and dimes and you don't want to spend all day plucking clad and clearing trash because you are either short on time or you really really want to outshine your hunting buddy with the Minelab (Hi Josh!) and want to focus on quickly getting to the wheats, indians and silver an inch or two below the clad. What is the best way to use the Deus to quickly decipher the signals and only go after the deeper signals?

In my scenario, let's say I've spent a few minutes in a yard and it appears the conditions are the same throughout the yard (EMI, iron, foil, pulltabs/bottlecaps, coins and depth) and I discover that clad is at the 3-4 inch level and I suspect the silver, etc. is at the 4-6 inch range (targets mostly range from 0-6 inches in my area).

What is your advice for program settings and operating methods that will enable me to cherrypick quickly, but not so quickly that speed would make me miss the goods?

Now, if I might guess at an answer (and feel free to jump in and correct me), here's what I would do as a person who's owned the Deus one week for a total of about 15 hours of use.

I want to be quick but I still need a little depth.
So I want to discriminate and perhaps notch.
I also don't want to waste time with the Deus' pinpoint mode, instead drawing an X over the target or wiggle back. (Or perhaps I do want to pinpoint to give me some idea of depth?)

Disc 10
Notch 0-30 (will lose nickels, gold and jewelry I know--but I can always go over it again if the yard reeks gold!)
5 Tones
Freq 4K (if EMI, try 8 then 12)
Manual GB set 2 points higher than ground and GB notch 85-90.
TX 1 or 2
Sens 80-85
React 3 or 4 since targets are not that deep.
Silencer 0 or 1
Iron Level 0
Audio Response 2 or 3

I really want coins to pop and be able to easily distinguish trash as well as quickly determine coin depth. Program settings are my secondary concern in this case--depth is more important here. What do you think? Thanks in advance for your advice.

get an ace 350... it is a coin magnet

What the deuce? You're in Deus!

Check your horseshoe. It'll give you a depth indication.

I wouldn't disregard shallow coins. I've found silver and IHPs in 3-4".

Ah yes! I forgot about that! Thanks!

My intention is to cover ground semi-quickly, then go over it again if there's time. I know what you mean though; I've found "keepers" at shallow depths too...for whatever reason; soil movement maybe. But some yards you can just tell with a little time, that the new and the old are distributed uniformly. Thanks Simon.

I don't see anything wrong there. Notching to 30 will cost you very, very little stuff that's worth digging, but you'll skip all kinds of junk. It should let nearly all jewelry through just fine, also nickels. (I dig nickels all the time while notching up to 35.) 4kHz locks you at tx 3, so don't worry about what to set that at. I have little experience with rx at 4 (I don't like what it does to the tones and depth), but rx 3 is probably a very good idea if you're not digging deep holes.

In fact, if I were cherry picking a site like that and only wanted coins (and would come back later for relics and jewelry and such), I'd run my notch much higher than that. I'd also notch out 95-99 or so to knock down wraparound. You'd only be hearing coins, some jewelry, a few bottle caps and large aluminum like that. One could cover an awful lot of ground very quickly with so few signals to evaluate. My girlfriend keeps a program like this saved for when she's in a bad mood and doesn't want to dig any trash at all.

If you do notch aggressively like this and you're considering another frequency, make sure to set up an entirely new program for that frequency with the notches adjusted as necessary to account for the different target values.

Dave, thanks for the very informative response!

I keep forgetting that 4K hardwires TX-3, so maybe I should use 8K so I can reduce the TX if I need to....I suppose that's yard dependent. If I don't have a problem with 4K and EMI, or too much power, then I'll stay there, otherwise I can use 8K.

Good points about notching--I might be a little more cautious about the high end notch and maybe allow myself 97-99. I think I've read where some halves can pop in at the 96 range?

Great tip about notching and different freqs. I think I read that same thing at metaldetectingworld. Andy's book will arrive early next week, so I'll be able to understand a little more soon.

As a noob, I definitely appreciate your feedback!
