SE and Deep Iron

[DFXer]

I need a little help here!

While detecting on fresh water beaches with streaks of decomposed iron mineralization, when do you dig an "iffy" iron signal? I've dug a few strange deep iron sounding signals and come up with pennies. It makes me wonder what I've passed over at other times. I hunt in all metal with ferrous sounds, reasonable sensitivity and a slow sweep speed.

I'm asking this question because I'm going over a hard pounded beach with slow deliberation and I'm finding a few surprises in the form of jewelry and older coins. I know that there is more down there but the audio signals are being distorted.

Thanks,
Paul

Distorted audio and visual is normal for deep targets, especially in mineralized ground. When in doubt, dig.

If it is not solid iron cursor location then dig. Audio can sound like iron but cursor location will be different, usualy the conductive hieght is more accurate than the ferrous location, left or right. The digital #'s are usualy useless when it comes to deepies.

A larger coil may bring some of the ID's up a bit, but with the mineralisation, it can have the opposite effect too. You are detecting at the peak range of your machine, just remember the screen is more accurate than the tones. Tones are for speed and screen is for accuracy (if it can be called that). That's why it updates sooooo slow. You will start to see patterns emerge that will repeat over and over producing like targets that you couldn't have found otherwise. What an exciting time for you ahead. Pay very close attention to your cursor movement, there are clues there and once you figure it out, it opens up another couple inches of depth for you, like a hidden key to a treasure.

Rich, thats the first time ive heard anyone say the screen was more accurate than tones. In most cases the tones are updated by the DC side of the coil and have no coorlation to the screen filtering updates. Thats why you get such wrap around at depth and some good targets show up on the negitive side of the screen. Maybe im out to lunch ... again.

No, you are right on Dew. The TID is the first to go on deep targets (on all machines) and the Tone is the only reliable source of information when hunting deep. Bryce (IL) brings this to light on just about every post of his deep finds. Read today's post on high $$ Indians.

Guys when I get to the edge of my SE's depth, I am not listening to a tone anymore, I am hearing a blank in the threshold in all metal and then looking at the screen to see if the cursor bounces towards silver or not, and if it does, whether it follows a pattern, or if it's just a one time occurrence. If your machine is still giving a tone to you, you could probably go a few inches deeper. It can only be accomplished in manual sensitivity pushed to barely stable. When I say barely stable, I mean not by holding the coil off the ground and checking for stray signals but holding the coil to the ground and listening for stray signals. Many times a sensitivity that seems too high with the coil in the air settles right down when the coil is near the ground. i only do this in sites that have proven to have "deep" coins. naturally, if you did it in a local park that you were unfamiliar with, you would dig a whole lot of deep garbage.
