Field2, advice on reducing high-tone iron

[pa-dirt_nc-sand]

I’ve been hitting some old cellar hole sites with Field2, recovery speed in the middle, iron on and power around 20, otherwise stock. I’ve had some luck over my last 4 hunts with some nice old coins and relics, but I would like to reduce the quantity of plugs that end up being square nails. (Some rust encrusted, some large 4”, some small nails, some nail frags or balls of rust)

I usually start by digging any target that bounces into high numbers (examples 16-17 or 24-25 or 32-33) with a tight tone at least in one direction and pinpoints accurate and small. If I start digging too many nails, I start hunting for these signals but looking for ones that stay consistent in all directions. Lately I’m digging a ton of nails with this set up and technique.

My 600 has the software update. Should I revert back to the original software? Should I mess with the iron bias settings. Looks like Field2 is stock at 0. My ears are starting to hear the slight difference between a falsing high tone and a good high tone. (Clearer signal, only bounces one number, with the iron on you don’t hear the more muted iron signal transform into a high tone)

Any advice appreciated. (I realize no detector will totally disc iron correctly 100% of the time, but with my typical 45 min max hunt time I need to be as efficient as possible with my target selections)

next time try flipping over into 5 or 10 kh and see if the vdi numbers jump way up i've found that most of the time iron signals jump higher, haven't tried it yet with square nails that have copper content though.

Thx! I’ll give it try. Sounds like a super quick way to ID an iffy high tone as falsing iron.

You could try breaking the halo then swiping the target again instead of removing it all together. This helps often on falsing iron.

That's if you're suspecting a false signal

Are you using AM and listening for accompanying iron tones? Not a fan of iron bias, you run the risk of masking a keeper non-ferrous that is in the proximity of iron.

I’ve experienced that. Getting a good hightone signal, digging a quick scoop and it dropping to 15 or iron or not consistent anymore.

Yes, I’m engaging the horseshoe button when at this type of site. The iron tones and what pinpointing reveal give clues. More hours on the nox will help translate a forced high tone from a true high tone.

Yeah, if I suspect iron I'll stick my shovel in the ground and give little pull then re swipe. Definitely a time saver, lol!

thats actually a really good idea, how have I never thought of that ? Thank you

High-V, what is your dig not dig criteria when you get a potential silver dime signal at the old trashy parks you hit? Consistent specific numbers? Depth? Tone? Other?

Depends on how much time I have at the site. It is really a case by case thing with me and is heavily driven by how my day is going. By that I mean what I have dug at that site that day. I'll dig all partial (e.g., one way) high tones at first then adjust as my brain adapts to the sound quality and it becomes clear that I have a a high probability nail based on the 10 or so I have already dug. I focus on the concentration of keepers and then go low and slow in that particular area until the signals dry up. So it is hard to give a generic dig-no dig checklist. Hope that makes sense. Not trying to be vague.

For me personally, it's a combined tone, VDI sequence (which seems consistent on the EQ) and most importantly is how the target pinpoints vs the actual signal response. If the target is a faint high tone and it pinpoints strong you can be certain that's a nail that is being detected and definitely more shallow than it seems. I dig a ton of iron still even if I suspect it to be so simply because I am still learning the EQ. I'm usually right on my guesses though lately. To me, it's the only way to learn.

V,
I would never characterize your info-packed postings as vague, and I NEVER pass up ANY of them,

He's definitely an asset on the forum. Tons of knowledge. Not afraid to share either!

Thanks. I just want everyone to have as much fun as I am detecting.
