first try with LS

[glenns]

Went out for two hours this morning and one hour this afternoon. I dug 3 half horseshoes and 30 square nails. My first question is how to seperate the nails as over half pastede the reverse discrimination test as did numerous flat pieces of rusted old steel cans. The site is an old calvary site right after the civil war 1869-187? Not discouraged just curious. I normally hunt with a 2500. any help appreciated

I would choose small areas and clear out all the iron first, or at least thin it out. Then, use the 1500 wand notch out the iron and go over the site again. It's a lot of work, but there should be lots of surprises waiting there for you. A PI is not recommended as a machine to hunt an iron infested area.

I've found the LS to be a pretty good Relic machine, even around Iron. I concentrate on the very faint Hi-Lo's in hard hit sites, these will be your brass buttons, copper, small lead (pistol and some larger cal bullets) and even small Silver ...usually ... but some you'll have to convince into a good reading and can start as a Lo-Hi. As far as the Iron goes, even VLF's love those half horseshoes, and if the cans are Tin, gonna be hard to avoid as a Relic hunter, but after some practice with this machine, she'll start discriminating for you. If the shoes and cans are shallow strong signals, try raising the coil as to not overload the system to get a proper signal.
On those nails, often they can give a solid tone in one direction, turn 90 degrees and sweep, a double beep is a good indicator its a nail, might have to pull a plug for better investigation. Also I've learned to recheck signals with the toe of the coil to investigate, what was a Hi might change to Lo, then follow it up with reverse check to final your decision.
To me, learning the good Lo-Hi's in conjunction with the tell-tales of reverse Disc has been the challenge. I've started investigating the Lo-Hi's out in the field, by turning up the disc to see where they fade out to learn the characteristics of the targets I'm looking for, and the ones I'm not. Also to see if the Lo tone changes to a Hi as Disc is increased to "3" or "4", is a good indicator of target I want to dig, of course after following up with Iron check.
After a good bit of hours with this unit, your gonna find a couple other tools, like sizing the targets, modulation, and Threshold nulls etc....

But this should get ya rolling,

Thanks I'll try that. I have hunted this field for about a year and half and have found lots of relics and 12 coins from the 1800's,mostly with a 2500 and a 1350, but thought a ls might help
