Going Field Hunting where a Ft stood in 1813, Adice what mode for F75LTD2

[nalc472]

Going hunting in a field that had soy Beans in it. Used to be a 1813 fort there. Using the NEL Tornado coil. Any idea what would be the best mode and settings

Depending how rough the bean-field is I would start with PF (Plowed Field). If it has been surfaced to smooth and you can run the coil close to the soil I would just use the default setting. Set the discrimination very low - like 5 - and ground balance frequently. I like three tones with high nickels (3H). You might try Boost Process, but that would depend on where you had to set sensitivity. If you can get it up into the 90's without a lot of falsing try Boost.

Just my thoughts. I'm sure everyone has different preferences.

 

[nalc472]

if you could take a e-trac or F75ltd2 field hunting which would you take. I am chosing the F75LTD2 because I believe it can go deep in a field situation with the tornado coil. If I can use Boost process I should really go deep

When hunting these old sites I use a disc of zero, otherwise it can (and will) sqew TID's on non-ferrous targets into the ferrous range. You'll get used to the iron sounds and then when anything that's non-iron squeeks in, investigate it. I used to run my disc at 4-7 when I had the standard LTD, but with the LTD2 being so quite and stable, I find that zero works much better. I also tend to run mine in BP mode, with the sensitivity at 99, BUT it depends on the ground. If it's mineralized or in a pasture with a lot of animal urine, BP mode with high gain can cause some falsing, so PF mode, or even DE mode and then set the gain as high as it'll go without false positive signals.

Earlier this year I found an 1836 bust half dollar in an area with a fair amount of iron that was pounded, and my friends had written it off. I gridded the area, went very slow, and dug the half at 9" + deep, it was a good, solid signal, but I think I only heard it because I was going slow. I was using BP mode, 99 sensitivity and zero disc with the 11" DD coil.

I also took some friends to another site a month later, a site that my other friend had written off as "worked out" and I had one of my best days of detecting this area - four Phoenix buttons, 1700's crusifix with the chain, 1864 indian head, a rare 1834 quarter reale from Sonora, Civil war eagle button, and a bunch of other nice buttons and relics. My friends were hunting with a T2 and a XLT and darn near got skunked (I think they got a couple of buttons was all). At this site I was also using BP mode, 99 sensitivity and zero disc with the 11" DD coil and going slow. Some of the finds were deep, and not five star, 4-way signals.

I plan to go back to these sites over the winter with my Racer and see how it does there, I'm sure there's more to be found

Good luck and HH,
Brian

I believe this site has never been hunted. The fort is as described:

The fort was a square building of sixty feet front, built solid, and pierced with loop-holes for firing from. The upper story -rather the roof -projected over the wall of the main building, so as to overlook the sides. There were four block houses in a line, extending about 300 to 400 feet, in which the families of the country congregated and lived when danger of an Indian raid was feared. It was at this time the extreme frontier of the country was in that direction, and was garrisoned the greater part of the time, for three or four years, by the rangers. It was suppose to garrison 40 to 50 soldiers.

Excited to hunt. Never know what I might find

did your friend know how to use is t2

Here is my fort research. You can see the 60 ft wide and 300 feet back. It matches the size of the un plowed area

OK, not to argue, but isn't the whole purpose of the F-75 platform supposed to up-average the TID's if iron is present?
Confused here.

 

[nalc472]

went to the site Sunday. It still had standing corn. Maybe next couple of weeks

 

[nalc472]

going back next week to hopefully hunt. will let you all know what I find

 

[nalc472]

Went to the fort 2 days ago. Found 3 flat one piece buttons. One is datable to about 1810-1830. Figuring out the lay of the land. Found the three buttons in the same area of about 50 ft. Will go back to keep working area. Have no pictures to post. Cannot find my cord to connect to my camera

 

[nalc472]

going back to the fort tomorrow morning. Hope to find some coins.

 

[indy durtdigger]

Good luck!

 

[nalc472]

back from fort site. Found 7 more flat buttons and a 1820 large cent that was drilled to wear. Oldest us coin I have ever found.

 

[still looking 52]

Now that's an old coin, Abraham Lincoln would have been 11 years old when that coin was made. How deep was that penny? You would think something that old would have settled way down by now.

 

[nalc472]

Here are some of the finds from the fort site. Two other buttons not pictured. These were all found using the Tornado coil on the F75 and the E-trac. My buddy was using the F75ltd2 and Me the E-trac.

Pretty cool indeed
