Depth experiment on ACE 250 and GTI 2500 - **UPDATE-**

[khouse]

You can run higher sensitivity on the smaller coils because they see less ground. The 4.5 inch sniper will beep a dime at 6 inches plus because you can usually run the sens wide open. The larger coil you have to run a lower sens.

I run my sense at one just below max on the 12 inch coil. What everyone seems to be doing wrong is your not digging the lower signals like foil,pulltab,or even nickle. once youve cleared the trash from an area the 250 with the 12 inch coil can see really deep. Your tector no matter what brand will pick up on the closest/biggest metal around, so if you have a can at say 10 inches and a dime at say six inhes which do you think the tector will register first. I know you thought your descrimination setting would take care of that nasty ole can for you, well sorry the 250 isn't a miracle machine like the fisher F-75 which clatms it can see right through a can to the dime underneath.

Btw if you dig those lower signals, you'll be surprised what you'll be finding hiding in amongst the trash.

tman, if your area is like mine most of the parks have been hunted over and over and over and over for about 20 years. Silver is very scarce. I've only dug two silver coins in any of the parks in my area. I have to do a bit of research and go outside the area to dig silver in parks or schools. Out of the way small towns are best for me.

If old coins are your thing private property, (with permission) is the best source nowadays.
If jewelery floats your boat then water tectins the way to go, or any place people get or got undressed on a regular basis.
CW or another war get your blood boilin then woods with histories is a best bet especially if they are first or second generation growth.

I live in an area where I'm blessed with all three.

When you go to bury the test coins place an anple supply of saly warwe in the hole and fill with dirt letting the dirt get wet from the mixture of salty water, heck that will age it like is had been buried to 2oo years for signal purposes in less tan 2 days time. It works I invented it and use it. bill

Here in Florida, where the soil always has sand in it, it doesn't always seem to be too conductive in the drier seasons. I do the same thing with either a LOT of plain salt, or both salt and saltwater every time that I put in a ground rod for electrical equipment (as I'm also an amateur radio operator. That reacts like a wonder to the copper and the sand in the soil for a great ground. Hence, what it all comes down to is that the salt content affects the conductivity and the halo effect that comes from a coin or other metal being in the soil for a length of time. Burying the coin (or anything for that matter) along with saline or salt by itself, will intensify the natural effect of the corrosion that takes place around the object in the soil. And yet another reason why I use salty water when I do electrolysis.

hey man if it is Depth that you are seeking from a Garrett machine, maybe you could try the Garrett Master Hunter with the 2 Box TreasureHound Depth Multiplier. I have heard from others, targets have been found up to 3 feet!! If you want to dig that deep! From what I have seen out there, this machine with the depth multiplier is the best deal for under $1000!

Cheers

It takes two men and a strong girly man to lift that add on two box unit. Well, that is exhagurating a bit but it is much heavier than I want to mess with. It's designed for cache hunting of large objects however and wouldn't be so hot for coins I suspect. By the way where can a guy buy that saly warwe? Monty

 

[melvin_it]

Hi Monty,
Your tests on Garretts are very useful to me, thanks a lot! Now I've buried some coin (Eurocents) in the yard and wait to see what happens... I recently learnt something on how anciently buried finds may be detected much better. My ACE found a medium piece of lead in a roman context at more than 12". I was suspecting it was lead but didn't told nothing..and workers were diggin and diggin (not only the spot but around it too) and they started lookin me badly ...!! It came out at last and one thing really surprised me:in air the ACE was unable to find it at more than 9 - 10".

I'm learning a lot new, amazing things on this art..


Bye. M.

 

[Larsmed]

Today I just found a tin cup at atleast 10 inches with my ace 150. Cant wait to see how deep the F2's will go!

I have a question regarding your experiment: Frist, were you useing the standard coil 6.5x9?
If you had used the 9x12 coil wouldn't you have gotten the coin buried at 10inches?

I think this would be a good time to start a test garden. Unfortunately I live in an apartment and don't know anyone around here who would let me do something like that in their yard.

I think if you did another garden now, planting a number of coins at different depths starting at 4in.....5in.....6in...7in......8,9, and 10, and letting them sit until say....April or May, this would give the coins plenty of time for the metal to enteract with the soil. Then I would try the different coils and the different machines. BTW if you have some gold rings or even a small nugget or two, that would also be of value to everyone logging on here. Hope you have the time to do something like this.

Everyone I know lives the apartment life. I suppose I could go to a park somewhere and plant something but my luck another detectionest would find it.

Regards
Robert Roy

Robert I was using the standard coil the first time I tested it on freshly buried coins. The last time I was using the ACE 250 with the larger coil and the coins had been in the ground for some time. Either detector will find objects much greater in size and deeper if they are big objects. The 2500 will give a default signal. I got that signal at an object over 10" deep according to the display. It was the door off an old cook stove. The ACE will just show the object as being over ...what's the max inches on the scale (can't remember without looking). Must be oldtimer's disease? And both detectors will indicate the object is over in the silver range if it is heavily rusted even though it is really iron or steel. I can pick up an aluminum beer can at a foot deep in loose sand at the beach as an example, but I have learned to figure out that it is a beer can or soda can instead of treasure. Remember, my test was only done on coins. Monty

You may want to try the whites coin ID. I have seen some tests and it outperformed, the ace 250. I am going to get another model soon, my ace is just not finding coins very well. ..Probably a whites 5 ID.

Monty is a BRAVE Man!

I know how deep I have found some of my targets out in the field but just for fun I decided to plant some deep coins and see if I could find them with the ACE 250 and the large coil and my GTI 2500 with the standard coil.

I buried a wheat cent and a silver Roosie dime at a measured 10 inches.The soil was barely damp and we don't have a mineralization problem here. The air temp was about 73 degrees and the relative humility was about 70%.

I first tried the ACE250 with fully charged batteries and ran through all the various preset discrimination modes, sensitivity at my usual 4 bars. Nothing, not a peep, not a hint of anything being in the ground but dirt! I kicked the sensitivity all the way up and then backed off two bars so it would stabilize, ran through the identical set and nothing again. I then held the pinpoint button down and tried it again but could not detect either coin. Disappointing but not surprised. I once detected a silver dime at 9" in a controlled hunt, but only that once and never again. I do have several finds at 6" and that seems to be about max.


The GTI 2500 was even more disappointing. I was using the standard coil and ran through the discrimination modes but no sign of a target. I switched to all metal and sensivity of 12 and just barely got a faint tone. It was not of sufficient strength that I would dig it in evary day use. I was really disappointed because of the almost thousand dollars difference in price of the two detectors and no more depth than I was getting with the "Cadillac". I have detected and dug steel targets from that depth with the 2500, but they were all in the iron range.....and large, very large!

So, from my results I would have to say my beloved Garrett machines are not the deep hunters I thought . Now I am not going to get rid of them because of that, at six inches or less they both are killer machines. For those of us who put much stock in depth, I would look elsewhere. Monty

Hats off to you friend! You are brave indeed even making a post like this.

Be warned, you could start a rare trend of truth in depth reports

With depth reports we hear this, that, and the other thing. Coin gardens don't lie.

I like you 10 times better for doing it. 8) You've got salt man 8)

 

[warsawdaddy]

I sold my 2500 this past july.Still have the Ace 250 and will keep it.But I also have the Minelab,the Fisher,the White's,the Tesoro(2ea).The little bit of detecting I've done,it seems like they are all about the same and that's probably more me than the machines.But because of Chas Garrett,I'll always have one of his units.I like that man.

 

[DFXDon]

Monty Your tests sound normal to me I ran the same kind of tests in my test garden a few years back and my DFX was unable to detect too Ten inches on newly buried coins are very hard on any detector in a few years of benign buried and the magic of corrag en sets in and both of your machines will have a better chance. Time will tell

 

[robert roy]

Hi Monty:
I have never picked up a target at 10inch with my Ace. With my MXT yes but not the ace useing the standard coil. The most depth I have gotten with the Ace 250 standard coil is just around 6inchs. Don't know anything about the Garrett 2500.

Gosh, Larsmed, I don't understand you not being able to find coins with your ACE 250. It has certainly proved itself a thousand times over as a coin hunting wonder. If just coin shooting playgrounds, parks, etc, I always use my a ACE and leave the heavy artillery at home. You either have a faulty unit or are having a hard time learning to use it. I have hunted places with mine that simply did not have any coins or at least not many within the limited depth of my ACE. When I first got my ACE I went back to a school yard that I had been over very methodically with another brand of detector and found several coins I had missed. I was really surprised. You gotta be missing something. Monty

Michigan, I call it as I see it. Always have and always will. I, like many am not stuck in a rut about any one brand of detector. Whatever it takes or whatever brand does the job for me I am going with it. Sooner or later when $$$ aren't so short I will try some of the other top of the line machines and when I do and if I like the results I will say so. I have to admit that some of the fault with my 2500 isn't the machine but it is me. Others report very good success with it and I have had some success with it also. I just don't get out as much as I would like to learn even more about operating it. Monty

I am hunting more demolished housing sites now and the ace seems to false all over the place due to the iron in the concrete ...So now I am wondering if a sniper will help me to find the treasure among that trash or if it will help at all at these sites...Because I know these type of sites could hold lots of goodies

If the sniper wont help, i will get a Tesoro. I need another detector anyways!

Larry

 

[stoney56]

Razed sites are well known for their trashy residuals including bits of copper pipes and pieces of alum. siding. A sniper coil would help in those situations no matter what detector is used.
