Primary Interest:
Metal Detecting
Just curious as to where you have your disc. On your atp pros set at? I usually have mine at 35, is that to high? Also I notched out I think it was 45 and down but why was I still getting hits at those numbers? Iam sure I heard a tone as well showed a number ?

I run mine in Pro mode with no discrimination. I like to hear everything and I just ignore the iron. You are not supposed to hear anything discriminated...but you are always supposed to see anything the machine finds...regardless of discrimination.

Hope that helps some.
 

What I do is experiment and try different things and then mark what I have had hits on then go over it with another setting to see what happens. I hunt usually hunt in pro zero with metal disc set at about 31 and iron audio off unless I hit an iffy signal then I turn on iron audio to ck it. I try a lot of different things to learn my detector better.

Everytime i get the upgrade bug my ATP seems to produce more. I am not sure after watching hours up on hours of U-tube videos on all brands and grades of detectors you can't do much better than the ATP unless you want depth and like the Spectra V3i where you get a lot different screens to help you see if it's worth digging.

There is no shortcut to finding the best setting, I have even noticed in some places I have to fine tune the ground balance and sensitivity for max results
 

I run mine in zero discrimination, iron audio set at 35 to 40. Below is how Garrett Detectors Read Canadian Coins:











Here is how the Garret ACE should read Canadian Coins....


PENNIES: Depending on their year and length of time in the ground, expect
them to read one notch before the penny icon to a couple of notches past the
penny icon. You have to dig dig dig.


NICKELS: Again....what year and length of time in ground. They will either
show up at the penny icon or nickel icon. They tend to give a smooth signal on
the nickel notch, not a rough sound like the sound of a pulltab.


DIMES: If 1968 0r older,(silver)they will read clearly in the penny range.
Newer, they might not read at all if freshly minted and recently fallen on the
ground. (not to worry, my buddies non-Garrett machine does the same) If they
have been in the ground, say for several months, they tend to bounce around
pulltab and coin. If you dig the plug and loose the signal, chances are that you
got a clad dime. You now need to find it in all metal mode (pinpointing) to find
it and remove it.


QUARTERS:1968 or older read in coin range, usually smack dead center under
the quarter icon. If new, again, might be missed. If in the ground for at least
several months, expect it to bounce around penny, quarter and pulltab icon.
Again, once you make a plug, you may loose the signal, so you have to use
pinpoint mode to find it and remove it.


LOONIES and TOONIES ($1.00 & $2.00 coins) give a strong signal under the
coil at penny or quarter. Garrett machines like these coins. If you get one
under your coil, you will surely dig it!
Summary on Canadian Coins:


If you hunt in coin mode and notch out the nickel and pulltab, you will still
get nearly all of your Canadian Coins, with the exception of a few nickels.
"BUT", you might also miss out on a gold ring too. So, based on your goals and
available time for a hunt, choose your programs carefully.


Some other makes and models of detectors will not read or barely read our
Toonies, Loonies, & nickels. I know from experience from hunting recently
hunted playgrounds, and that's what I usually found...nickels, loonies. toonies
and some other clad. I suspect that Garrett engineering designed their machines
to detect these one and two dollar coins, as I sent them one of each several
years ago. I am also hearing from others using the recent Garrett lines of
detectors getting the same results.


AT SERIES METAL DETECTORS




Because nearly all detectors are made in USA, they read U.S. coins with great
accuracy. When hunting Canadian coins, you need to slow down a bit, and if you
get any signal at all, you should go over it in different directions.....to see
if it will read and bounce around in the coin and pulltab range.


These readings explained below are found using the AT Pro in PRO Mode, Zero discrimination, Iron disc set at 40 with the iron audio turned on. The same results will be found on the AT GOLD In Disk 1.


PENNIES


Older pennies, up to the middle 1990's will read in the penny icon, or with a VDI in the 80's. Now the newer strikes, can be made of metal or zinc plated with copper. These are harder to ID as pennies, especially when the copper coating begins to wear off. But, expect them to read as a steduy VDI reading of 74 +/- about 2%. Others will read in the high 70's and lower 80's. The key is where the VDI numbers read MOST of the time. If you decider to NOT dig pennies for whatever reason, expect to miss some silver rings and 10K gold rin




NICKLES


They usually give a softer sound with a VDI reading at 50 +/- 2% and remain there. Square pull tabs give a harsher sound and often times reamain at 53. Gold is common in this area +/- 10% with a consistent softer tone.




DIMES


Older silver dimes, (pre 1968 ) or older will read as silver and read in the lower to mid 80's. However, if they are beyond about 6 inches in depth, they may start to read as junk. Use your common sense rule that if it is deep, it is probably old. Now freshly dropped dimes will read loud and allow the VDI numbers to bounce around the 60's to the 90's. With the IRON AUDIO turned on, they will grunt (low iron) and give a nice loud sound in the 80's -90's. Dig them, as they might also be a quarter. Older dimes tend to fluctuate in the 40's to 70's with the odd spike to the 80's.






Quarters


Pre 1968 quarters were silver and will read in the 80's consistantly. New fresh dropped quarters give a loud signal, with a VDI bouncing back and forth between 30's - 70's. You will eventually learn their distinctive audio. Older (not silver) quarters tend to bounce back and forth around the 70's to 80's. They also give off a loud signal.




Loonies


Give off a very loud audio bouncing back and forth 70's to the 80's.




Toonies


Give off a loud signal in the 70's and can sometimes give off a spike to the 90's.








Some results will vary if detecting to sanded tot lots or areas with higher soil mineralization. The soil in my areas is basically low to moderate. Good luck, and if you discover any other good tricks for detecting Canadian clad, please comment.
 

I also hunt in Pro Zero Mode, Iron Disc at 30-35, no notching at all. I do an auto ground balance periodically during my hunt. I will also bump the auto GB down a couple of points manually. If I am getting a lot of chattery noise, I will bump the sensitivity down a notch until it settles down. Hope this helps...
 

Wow thanks!! A lot and I mean a lot of good information guys! I keep forgetting that the atp pro is setup to identify American coins a lot better then our Canadian mixed up metal coinage. But with the looks of what the weather is right now outside I think my hunting is pretty well done for the year :(

The AT PRO is full of surprises run no discrimination on the beach get tone but no ID or DEPTH than can show ,I decide to dig and see what is going on here at 9 IN an old coin side 0.7 IN . When a coin or anything that is to deep the at pro can't show any id but dig .that detector don't shout for nothing

They say if you ground balance your AT PRO on wet sand salt water sand you can loose sensitivity to gold WRONG I find part of a gold chain signal loud and clear solid 51

I'm already having hunting withdrawal looking outside and watching the snow hit the ground :(

hey sask ..you need to come down south for the winter....It gets gold here in upstate south Carolina....but we have very little snow and the ground rarely freezes....when it does its only an inch or two

Now ur just teazing cause I have already about 2" of snow on the ground :( and just waiting for the -35 weather to follow , but hopefully that cold won't be here for another few weeks

Actually the iron discrimination is good for trashy area that have lots of unwanted iron trash other than that zero mode and listen to the iron tone
