School me on iron and Tesoros :help:

[BusDigger]

New owner of a DeLeon, hunted with it once (yesterday at 3 different locations). I'm not displeased at this point, just trying to learn. I'd ran in both AM (light hum on threshold, disc from 4-7 at times) as well as in Discrimination Mode (both super-tuned, an experimented with both threshold & discrimination settings. What I was trying to eliminate was the constant chatter from iron, as well as the "lift coil" text or symbols. I mainly prefer to hunt sites where buildings once stood (but are long gone) or around existing older structures.

When set in AM Mode, I found myself constantly having to watch the screen because of the non-stop iron signals. After switching to disc, and notched-out everything below foil, it was non-stop chatter from all the iron. This occurred at all 3 sites. I don't think I will ever get used to that humming in my ears, but also wonder about all that chatter in disc mode.

Am I missing something?
Something set incorrectly?
Or is it just what it is?
Did I buy the wrong model?
Or are they (Tesoros) all basically the same in regards to iron?

I didn't want to spent that sort of cash for something which functions in this manner, when I have a cheaper detector that seems more stable (for lack of a better term) in the same fields. Matter of fact I'll likely use it tomorrow if the new site(s) cause the same reaction with the DeLeon, unless someone can explain it's operator error, and that's quite likely

Thanks!

usually if you cut the sens back where it sort of levels or stops chirping and falsing that will usually do the trick or might be in some bad ground to that will make it go crazy to, but try at first cutting the sens first and the threshold back a little as well only other thing you might be experiencing some odd ball EMI probs thats the only thing that i can think of to do and i've owned 5 of them

Larger iron targets will make mine beep once when the coil is swung fast over them, but when i go back an do a slow sweep to check the target the id will show iron and zero. The only time I've used mine in AM was when I was trying to help get a target pinpointed so I can't offer any help there. The lift coil message is when there is a target either on top of the ground, just barely in the grass/buried, or a large target such as a coke can or large piece or iron, the machine is trying to tell you its circuits are being overloaded with the coil that close to the target. Other than that have to agree with amcjavelin, back of the sensitivity and see if that helps any, I've never had any real problem dealing with iron but then I don't hunt old homesites either. For most of my hunting I run the D superturned, threshold all the way over and sensitivity all the way into the red unless I'm getting some chatter then I back off till the machine quites down, disc set to pick up nickles then just watch the display and numbers when I get a beep to see if i want to dig or not. Hope this helps some. Jimmie

Smitty,

I have the Vaq (beep and dig) and I have problems at old home sites that are littered with iron scraps. Most of it is near the surface so it gives an overload signal. In addition to that, much of the iron had plating on it and along with the rust, it disseminated into the earth around the iron object. What you get is the halo effect with an alloy that will help trigger the disc. If you remove the object from the earth and wave the coil over it, you will notice that it doesn't react the same as when it was buried. I once had a Cortes, it drove me crazy because it would false all the time even on small objects. So its probably not the operator I think the Cortes circuitry is very similar to the Deleon. I tried all kinds of settings and nothing helped, it may just be the nature of the beast. My Cortes had a preset GB in disc mode and that's where the problem likely was. The problem with that is I have mild soil where I live but find that I have to re-adjust the Vaq often in different locations. Good luck with your searches, I seldom do old home sites because of the high grass and the trash removal required. Seems I could spend a summer digging out the debris in one yard just for a chance to find a couple old coins. I'm not that patient.

Near my house is a small park that was a farm way back. The soil where the farm house was is loaded with deep rusty nails. I suspect there is silver coins below the nails. All 4 of my detectors give me iron signals there, just iron signals and shallow coin signals. If I was trying out a new detector I wouldn't go near that iron infested area because its impossible to get a deep coin signal. About 200 feet from the house I found 2 NJ coppers and another large penny, almost no iron was in that area. I think you gotta start out in a cleaner area to find out what the Deleon is capable of.

another thing that might help you at these sites is a smaller coil when i used my deleon the first coil i would start off with is the 4" coil get all the good stuff from that depth and work up bigger and that seemed to work good to and as the others have said there is alot of big iron that will over power the cicuitry a bit so start small weed the good stuff out best you can listen to the tone as well very abrupt sounding signal is loud and and sometimes chopped where the a coin is smooth or repeatable usually unless its a nickel sometimes can decieve as almost broken up a little bit.

Thanks for all the replies! I may just have to try to continue dropping the sensitivity it sounds like. Generally there's no EMI concerns, as there's no power on or near (overhead/underground) the sites we hunt. Yep, I was aware of the overload function (I've read the manual a few times). And correct, the DeLeon is supposed to have the same circuitry as the Cortes (which was one reason I decided on it). These sounds (crackling) are similar to radio static, only one "crack" at a time.

I'd had a couple aluminum cans (deep) show a solid 95. I understand no detector is 100% spot-on, just mentioning this for others new to these machines.

Thing about these old sites which are now in crops is, over the years things get strung-out as the fields are worked. This is one reason I wouldn't switch to a smaller coil, it'd take 2-3 times the amount of time to work a site.

I may just start-out with the 350 since it doesn't have that problem, use it for a quick once-over, then go back with the DeLeon....maybe save the "practice" for yards and other cleaner areas.

I'll know more after tomorrows hunt, and will update.

Thanks again for the help!

ok so your workin in a field sorry about that i thought you were in a wooded area where an old homestead use to be and all remained was the cellar hole ok do almost the oppisite of call size and run try running your sens about half way and see what happens from there.
