the Nox recovers so fast if there is a target near iron you will hear the non-ferrous tone

"the Nox recovers so fast if there is a target near iron you will hear the non-ferrous tone"

Hello
I am new to metal detecting and I just got the nox 800 and have been trying it out for 2 weeks now

the line above has haunted me since I got going, all I have recovered so far is nails
which gives a positive signal from 11 to 18 and flashes in the 30's sometimes and repeats a 30ish id
and tone is medium

I choose to dig them as I know Nickels come up at 13 to 16, I have increase iron bias up and down but it still the same
I switch into to all metal to listen to the grunt, but the ground just grunts everywhere anyway on old house sites

on my last trip, I choose not to dig these signals, and concentrated on numbers 20's and 30's that were steady and repeated themselves

still got nails , larger square headed and a few in the hole.

going a bit gray in the head , and hoping to see some light at the end of this learning curve tunnel

"the Nox recovers so fast if there is a target near iron you will hear the non-ferrous tone"

I am open to all suggestions and will keen to try anything at this stage, and any videos, or links to other postings are very welcome as i know nothing

the advice I got so far is "get to know the tones" "iron Bias", "don't use Multi Lower frequency" "use 20khz only"

but nobody has explained why

I know the lack of experience has a lot to do with it based on all the positive reviews from guys detecting old sites they cleaned out with other machines, and now finding a whole new pocket
full of things
 
Keep the iron bias at 4 or above and give it time, you and it will start to click.
 
4? 2 maybe..... which gives a bit more info on iron. Try using the AM button and lowering your first bin to 2. It will give a soft iron grunt that you really wont notice. That will move a lot of those digit readings to the iron range. Then you can always flip back and forth if you want. I dont know what sensitivity you are running...... but try it as 20 and work from there. The other day i dug a gold ring in the salt water and i heard iron as well. Ended up getting the ring, a fishhook, and tiny iron chain all in the same basket. Also..... recovery speed lengthens the tones... increase it if need be. HOT isnt always the best settings. The machine reacts more to iron..... and EMI.... and has to process more soil.... which includes more junk targets.

The lower your Iron Bias the better separation you will get if a coin is next to iron.
The higher your Iron Bias you will not be able to hear the coin next to the iron.

In my test bed in the back yard I have a coin next to and below the level of the undug iron. If I increase Iron Bias I cannot hear the coin at all.
 
I have never found a nickel above 13. Most fall between 11-13.

The old trick of using a cross pattern over a target is true with this machine. Another trick that might help you is to cut the outline of the plug out and and recheck the plug. If Iron with halo it will have been broken and no harm to the ground.
 
OK Amergin....BRAND NEW to detecting are you? If so,before you even worry about the brand of machine or coil you’re using,there are BASICS to detecting which will help you to avoid digging bad things,especially if you are a coin hunter. One of these “basics” is that in order to “qualify” the target in question,it must repeat as you swing back and forth over the target and it must do the same when you turn 90 degrees and do it again. This technique will knock out the majority of nails masquerading as a coin.
Now...go try again with this technique and see if you can improve your keeper count. Don’t go for the difficult or “weird acting” targets that MIGHT be coins right now. Just dig signals that repeat clearly in the coin range and repeat clearly at 90 degrees.
You have to start SOMEWHERE to understand what a “good signal” even sounds like.
 
Thanks! So basic! And, myself, I am new, and really needed this! No matter how basic this may seem I am sure that I have been overlooking this! How many have overlooked basics, and needed to return to this?

IDXMonster, Thanks! I am sure this will help me!


Only a few days ago, with my V3i still in the learning process, I dug a nail, and a nail, and a nail. It was all the same nail! In increments of the same 'old nail'! Perhaps, it was a close VDI to a quarter. And, it was a nail!
 
Nails usually hit 17-19 for me and turn 90° they may shoot up but iron bias at 2 does away with the filthy things!
 
Idx gave you good info,its tough out there and youtube days are hard to come by.stay at it,learn everything you can and even bad days are nice just to be out swinging trust me I know.ive had great silver,cw relic days and days where I cant even get a Lincoln but I enjoy it at the end of it all,may get flustered some too!
 
Dew, Thank you for taking the time to help me see through the fog, congrats on the gold ring what do you mean by " in All metal bin to 2"
 
When learning to detect as a beginner or even learning a new detector as an experienced detectorist, jumping into a nail infested site will cause you grief. It maybe best to start out in cleaner ground and get some experience learning the tones and the settings. You need to dig a lot of clad in a park or cleaner home sites and get proficient at it. Once you have some time behind the detector, you won't be so overwhelmed by all the signals.
 
Find some good open ground. Take a handful of targets ( quarter.dime.zinc penny ,gold ring, pull tab} and take turns digging and burying each target. Also take along a nail to throw in . An hour of this and you'll be ready to go !

My suggestion of 4 or above for iron bias was due to him being new to detecting, with iron bias at 4 or greater he should be getting very few iffy iron nail signals and could then concentrate more on the solid coin signals, and once he is more confident with the machine he could go from there, but in my haste I failed to explain myself. I find that if I run iron bias at 2 or less I occasionally dig small tek screws and the like that disguise themselves as good targets, so as a starting point for the original poster I still recommended a higher iron bias until comfortable with the machine.
 
Tried a test today with the Nox, with the iron post in the tot lots, i put a dime next to the post and swung the Nox, i would get the iron sound of the post but not the dime, kept moving the dime out until it would pick it up, it finally saw the dime at 5"away from the past. This really bothers the Nox with big iron. Used standard settings with park 1 and park 2
 
The big coil doesn’t work very well close to the play ground equipment . Wait till the new 6” coil comes out and you’ll see that you can get much closer to the metal bars and you should be able to detect that dime . I use my deus with the 9.5 x 5 coil and I can get within about 1 1/2 away from the bars and still be able to tell if there’s another target there . My opinion, the big coil is good on the beach or open areas . And until that smaller coil comes out for the equinox , I’ll use the deus in the tot lots and really trashy parks.
