Search coil size and coil type can be some of the most important considerations! I have a smaller-size coil mounted on each detector model I use, and a few models have a mid-sized coil, such as a 7" round Concentric or an elliptical 5X9½ DD. I don't have any detector wearing a larger-size coil unless it is a specially application. All of my smaller coils range from 4" Concentric on a Fisher F44 to a 5" DD on a Tek. Omega 8000 and T2+, and 4.7X5.2 DD on a Nokta CoRe and 5" DD on a Nokta Relic, plus 6" Concentric coils on my Tesoro Bandido II µMAX and Silver Sabre µMAX. I've relied on smaller-size coils for 98% of my hunting since about late '72 so why change?Quote
Junk and Disorderly
I would have said it was more about the coil size than the detector, some specific detector are better than others, but for me when i hunt in thick iron or trashy sites then only a small coil will do the job and i mean small in the 4-6'' size. If i suspect that decent targets are around then i will clean the site out of iron with the small coil and then use a slightly bigger one, then rinse and repeat using slightly larger coils.
If you use a stock or larger coil in a iron infested site then 'nulled signals' will be the norm, so for me it would have to be more coil size than the detector, on some of my old roman/saxon sites i use my faithful old T2 and 5'' coil or even my old Tesoro with the 4'' coil. once i happy that alot of the really troublesome iron/trash is out of the way and i want depth but still get in between iron that is deeper than i use a Nexus MP with the 7'' coil on.
Other folks may tackle this type of detecting scenario differently, but for me its all about the coil size.
For decades I often look for or search for dense iron contaminated sites in good-target potential sites for the same reasons ... others tend to stay away from them. Yes, I search the outskirts of ferrous debris as well but especially since '83 I usually grab the best detector I have on-hand for handling dense iron places, then keep the Discrimination as low as I can tolerate, use a smaller-size coil, and hunt slowly and methodically to pull whatever I can out of the ferrous debris. It is a real challenge. I used to use BBS an FBS models, but also had other devices better suited for when I was hunting nasty iron overloaded places.Quote

I will be following this one myself.
My tendency is to hunt around a place until I hit iron, then slow down and hunt in the area BUT... I often find myself just skirting the outskirts of it, instead of going headlong into the iron.
I have played with a few machines that have the reputation for being great iron unmaskers but still no where near an elite level for hunting in it. I have two such places on my own property like that, in which a machine like the CTX/eTrac or Sovereign will null the entire time the coil is within a foot of the ground.
Note how many of us are paying attention to search coil size. That's important, as well as how a particular detector handles all trash, especially rejected or Discriminated trash to be able to recover and provide a fast-recovery after dealing with nearby harsh target rejection.Quote

For me it is recovery/separation speed and coil size. Hunting with the Deus or Nox I can turn the recovery speed up to help get in between the iron signals better. At some point the iron saturation level beats the current detecting technology and it becomes an impossible situation. That is the point that it becomes necessary to just dig it up and sift through it.
And here we had a simple response pointing out one of the two all-time best detectors I have ever used for serious Relic Hunting challenges in dense nails and other ferrous based junk. Naturally I am a bit biased because I own 2 Nokta FORS Relic and 2 Nokta FORS CoRe devices, of which I haven't found any make or model to best them in side-by-side comparisons ... from any manufacturer.Quote
D&P-OR
For this situation ("ugly iron")----the Fors Relic with 5" coil is the best I've come across.
It can be fun, when you're in the mood, to get real serious and hunt in the terrible iron debris, but with the right detector and search coil ... and if you like the unit and it's performance .... then you can maybe enjoy some success. Like you, I know the Equinox can handle some bad iron conditions, but I just don't like the audio. Same goes for the Deus. I do like the performance of the Racer and Racer 2 in iron plagued sites with an 'OOR' or 5" DD coil, but prefer my CoRe and Relic models. We're all going to have our likes and dislikes but for anyone planning to dive into some really tough iron junk, pick a good, functional detector that is proven to do OK and be sure to affix a smaller-size search coil on the working end.Quote

High conductors are much easier to pull from iron than low conductors, you can use 14 KHz machines to pull high conductors pretty easy. Low conductors require higher or multi frequency machines. The machine also has to have fast recovery speed, But I'm going to have to agree with junk and disorderly that coil size is very important.
I love hunting iron laden spots because most people avoid them. My two favorite detectors at the moment for iron are the XP Deus with the 9" HF coil and an old Makro Racer with 7" concentric coil. I know the Equinox is good in iron (and I do have one) but I really don't care for Equinox in heavy iron even with a small coil, the audio just doesn't do it for me. The Deus has the best audio in iron of any machine I've ever owned, it has a way of blending the audio of a good target with iron and makes it easy for me to pick out the good stuff. I just wish they would make a smaller coil as the 5 X 9 isn't much better than the 9" round.
The Makro Racer with either a 5" DD or 7" concentric works the best for me in the real thick stuff. I'm talking bed of nails with nails literally every 2 to 3 inches. The one thing I don't like about the Racer is the overload, I have to cut the gain to 55-60 and swing the coil 2" about the ground in these areas, but boy can it pick out good stuff in the thickest of iron.
What I want is a metal detector that can see through iron. I'm not talking about laying a nail on a coin and being able to pick it up, I'm talking about having a coin 4 inches below a bunch of nails and being able to pick it out.
