I hate to preface this by stating the old saw about DD coils having a "blade shaped" detection pattern. Perhaps in the mid depth ranges they do but this question goes a bit further.
When I tried out the T2 a couple years ago for iron hunting my setup was strictly PF mode, disc 21-22 and senstivity in the 70's. With those settings the T2 needed a lot of overlap to pick out the

iron or "nickel type" metals have been with the ID Edge. Simply dig everything that bounces iron/non-ferrous or gives a semi-repeatable non-ferrous reading. The 6" concentric coil works very well but, the stock 8" coil should not be ignored.
I have never used the F75 but have used the T2 and while the DD coil is very good at unmasking "co-located" targets a bi

In my ground using the stock coil, target ID on the MXT was inaccurate beyond 6" and TID averaging on iron co-located targets is not up to par compared to any of the Fishers. Best used as a beep-dig machine and very good at that. The MXT ranks right up there as a dry sand or fresh water beach machine due to its sensitivity and great small iron disc range. Tiny bits of foil give an audio si

that FTP is working on the next best thing. The only question is, will it be a specialized (ie: relic detector) or an all purpose machine.
Something that goes WAAY deep in mild ground ala Nuatilus yet can be used elsewhere would be real nice.
With todays technology regarding ground handling it would be real easy to have a built in feature that tells you just when you can use the "t

Got a question for ya Tom,
Why do some detectors handle wet iron better than others? Can the reactance/skin effect actually oppose current flow?
My experience using various detectors has the results so "all over the map" that I can't make heads or tails of this effect!!
Simple question but I bet the answer ain't!

In my experience iron ID is improved as well as co-located targets giving better.. more repeatable "hits".
Nulling the iron is A topic for another post.

By clean dirt I meant balancing at the hunting site over a metal free area.
Multi freq detectors can use the different channels to help minimize the effects of ferrimagnetic minerals and by reducing the response to maghemite the effects of iron/rust are also reduced. What I am suggesting is single freq with two sets of data points to help determine the magnetic/conductive characteristics o

How about a dual GB system based using the nominal "clean ground" balance setting and a fixed (ferrite?) GB balance point which would give two sets of data to more properly analyze and eliminate magnetic minerals/rusty man made iron?

freaky thing but it can/does happen. something just a bit different about the skin effect on a particular item and how the phase analysis is done. Just my opinion
An aquaintance of mine found a large silver ring and the ID Edge I had at the time read the darn thing as iron. go figure??? Saw certain combinations of non-ferrous co-located items read as iron on the Coinstrke as well.

for the info on the F70 and C$. Thinking back to when I had the MXT I believe the Relic mode had the tone break follow the disc setting. Never used it much as I preferred the C/J mode for its iron range adjustment just below 2 on the dial. Very informative audio on low conductors when set in that range.
Yup the C$ will trump the CZ in several situations. Shallow fresh water wading over expo

I to would like you opinion on that Tom. A true threshold type sensitivity adjustment from what I understand should not lose a mid depth target that gives a decent response even when turned to minimum... as with the 1270, X5 and T2. The Coinstrike was one of the first detectors to seperate the sensitivity and threshold functions but, what we don't know is what Dimitars thoughts were on how

in an older park fully expecting to retrieve a Buffalo nickel. What I got instead was an IH penny that "should have" given the tab/zinc bounce. Of all the odd TID recoveries I found with that old CZ5 that one stands out the most in my mind. Kind of like your Barber dime experience which I'm sure you will alsso never foerget.

Hi Tom,
It's almost impossible to add anything additional to your post information wise that may benefit someone because you covered so much very well.
I can only add this, even with the DD coils you need to overlap, overlap and overlap some more in high iron infested areas. Just as with concentrics these new DD coils most definitely have a small sweet spot at depth for hitting co-locat

1270 is - 15 years ago
like a hyper 1236 around nails and the big iron gets through no matter what. It's do-able at low disc in small iron but man what a headache from the noise. As far as coins go, the 1270 needs the bigger coils to hit the deep dimes (and the 10.5" will hit em deep). It's hottest and at its best from about zinc on down.
The volume and sensitivity controls interact in ways that n

can compare the 1236X2 to a Cibola or Vaquero and it compares more than favorably for hunting in iron. Gotta disagree with Tom D on this one, the 1236X2 is super at picking out targets in iron. Set the disc to just click on small nails and hunt slow, the good beeps come thru plainly through the noise of the iron.

In fact with a "perfect" sweep it will give a very accurate ID on the non-ferrous target equal to what it reads once the iron is removed. The Edge and T2 make for a great pair to hunt an iron site with due to the difference in frequency, coil types and circuit design.

Yeah I agree you are a "nutcase" LOL
I sure wish I could hunt like that at my iron infested sites. It would take days to get thru even a small area!! I look for any indication of non-ferrous and usually dig stuff that bounces iron/low foil but you are talking pretty extreme detecting with your settings and mindset!
Yep hunting the old iron you gotta try fast vs slow sweeps comb

Hi Tom,
What kind of initial "hit" did you get that caused you to stop and check the IH out or were you taking the time to check out every small sounding hit even if it was a low iron TID?
Did you happen to hit it well centered on the first sweep or was it somewhat of a miss-sweep??
When sweeping from different angles could you always work up a non-ferrous indication using mono

Its a lot different than the 1266 around nails and iron. It still calls some deep iron as non=ferrous but mostly only the weak signals from tiny bits of rusty wire or small rusting away nails. Most big iron is easy to ID from the audio response alone without having to size it which is very handy and a great time saver. To put it simply... a great "audio only" detector!

Ron,
I agree it should read no audio response. Also when they say it is iron that is where careful resweeping of the target to see if you can get a fairly consistent tone or ID may result in some good finds.

A dealer told me that the sensitivity control on the 21 operates in a more linear fashion than previous machines. In other words, air test results increase gradually as the sensitivity control is turned up to near the max setting, rather than the big jump seen between 4 & 6 of previous CZ's.
Nickel is still high tone.
Time will tell how it does.

Thanks again Tom.
What I meant on the foil was that the sensitivity was around 70, not the TID reading. That was close on to proper in most instances.

I had mentioned this audio difference I noticed to Dave in an email and he also said that there were things done in this range (21 vs 20) that most would not see.

Did the X-70 user have the tracking turned on? I have seen much better performance around most types of iron with the tracking on. Case in point, an on edge dime at 6"+ near iron, properly GB'd but with tracking off signal was only good from one direction of approach. With tracking on it was nearly a walk around signal with the double beep coming in at times. Also, unless you a

Hi Tom - 16 years ago
Have you had a chance to do a head to head comparison of the X-70 to the CZ's in your sandy soil down there? Just curious how they compare in your conditions as on low mineral fresh water beaches up here in Michigan the 70 is a deeper keeper for coins. I know conditions vary so your low mineral ground may not equal mine.
Thanks
Tom
