Separation in Iron

[Canewrap]

The old GMT 1650 had a reputation for being a great detector when hunting in an iron infested site. Is there anything today that has that kind of separation, perhaps with a little better depth? Like 8 to 10 inches on a target?

But you will have to remove alot of masking iron to find the good stuff. No detector that I have heard of can see a coin buried deep directly below a carpet of rusty iron nails. A good operating orig. Bandido will work wonders at a site like that, beep & dig, don't need a meter in a situation like that. MHO.

Gmt is a great MD I say stick with what you got. HHH.

When you say "8 to 10 inches on a target", I assume you mean coin-sized targets, right? If so, as you know "8 to 10 inches" on a coin-sized target, is the power-house machine's depth range (ie.: explorers, CZ6, etc....). And no, NO machine that see through and around nails good, is going to do that at the same time, WHILE attaining power-house machine depths on those coin-sized targets (hub-caps perhaps, but not dimes, pennies, etc....)

It is the very nature of the deepseeking coin machines to excel at depth, with the downside of lacking on the target-averaging (ie.: see through) and target separation (ie.: see around) dept. So a machine like the Bandido that Hombre talks about, or the Silver Sabre, or the Shadow X2, or any other number of 2-filter machine will do great at seeing through a nail or two, to get a conductive beep on the coin underneath them (assuming you don't have your disk way up to pass tabs, etc...). But no, they will not do this while still going "8 to 10 inches" on a coin.

When you are hunting in iron infested areas, depth isnt necessarily the most important thing. Here is some interesting information. I have tried this test with all of my detectors and it is a eye opener

I can tell you from tests that the Tesoro I use is better than the teknetics delta and the ace 250 for defeating the iron masking. I know some will not like to hear this but, seeing is believing. I did some tests and that's what I found.

Just being honest.

I do still have my delta and it's great , both the ace250 and the delta are great machines, and I really would advocate people buy them. They just did not do so well in my tests.

What Tesoro detector did you use and what coils were you using on the 3 detectors? What was your disc settings for your detectors. I made the nail test board. I tried my Tesoro Lobo ST with the stock elipical Double D coil and the my Son's ACE 250 with the stock concentric coil on the nail board, and the Ace gave a better response. I disc out nails only with both detectors. Maybe the difference was the coils?

I just placed one dime under a rusted nail.

Cibola, sens around 6,disc just above iron.
Ace was 4 sens , and disc out iron, all other notches in.
Delta 4 k ,sens at 8 stock,disc above iron.

All stock coils.
I tried to make all settings how I would normally hunt ,and all similar modes.

I have a vid on the delta vs the cibola. I will post.

Here is the video , the ace bounced around very similar to the tecnetics. On all detectors the nail by itself was not making a sound. I did not sate this in the video, and the ground was cleaned before the test. I did not get a chance to record the ace, I sold it after the test.

Well I just did setup like your nail and a dime. I ran the ACE 250 over first with iron disc out. I first swept the coil along the nail and then across. The display bounce like you said, but I most likely would have dug this signal just because it sounded good enough that could have been coin. With the ACE 250 giving me a bell tone.

I then took the Lobo ST with Double D coil with the nails disc out and swung the coil along the nail I got no signal. When I swung the Lobo's coil across the nail I was able a really good repeatable signal. I defiantly would have dug.

It seem to me that a concentric coil will get some type of signal no matter which way you swing the coil over the over nail and dime and the Double D will not. I would geuss if you wanted to detect in nail infested sight that a 4 to 6 inch concentric coil would be ideal.

Left4Dead have you tried making one of those nail boards it is an eye opener. I tried the Lobo ST and I could not get a sound on the dime until I unmasked it by turning down the disc to accept nails. I was able to get response with the ACE, but I am tinking that if the ACE had a Double D coil it would never have gave peep.

I like my MXT by Whites for iron separation it will pick out the good stuff! In my test garden I can pick up a 1960's copper penny loud and clear at 12 inches and can lift the coil higher off the ground a couple of inches and still pick it up! I posted the Whites video part three 1:15 sec. into the video they answer your question. HH

The mxt look like it works great in this test. And I'm sure it's an awesome detector. But at 4.3 lbs it 2x heavier than delta4k,cibola, and still heavier than the ace250. Also it's quit a bit higher in price. I would expect this put of a detector that costs that much.

I love swinging the lighter detectors.
