SENSITIVITY SETTINGS IN NAIL BEDS

[Wild Colonial Boy]

Is it smart to lower sensitivity down to 15 when detecting in nail invested sites?

what do the experienced advise??

If that's what it takes I'd try it in park1. I don't mess with advanced settings much so cant help with iron settings. stock park1 has iron bias but park2 doesn't i believe so switching tween the two might help.

What are you trying to find in that iron? If shallow targets, I'd raise the recovery speed and work a bit slower. If you need deep targets, I'd lower the recovery speed and work even slower. I'd also keep the sensitivity up as high as I could without it falsing.

Thank you, I have read on other detectors, with lower sensitivity on nail beds, that are 2-6" thick
make hearing good non ferrous targets better ,
the added amplification higher sensitivity gives only exaggerates falling and high tones from coin shaped like iron

just wondering if any equinox users have tried this

Iron sifting (lowering sensitivity) in action here http://www.treasurenet.com/forums/equinox/586902-iron-sifting-advice.html#post5912627. It works!

As you can see from the responses here, some folks are loath to back off on sensitivity, but it really can help keep thick iron from overwhelming the detector, and some nice, typically shallower, masked non-ferrous targets can emerge from the muck when you do this. It takes some patience and determination to stick with it, but it can produce results. Just another tool in the toolkit. In other words, I would not solely hit a site with a sifting program, but something to try when adjustments in recovery speed are not helping you to unmask keepers.

when it gets out of the sick house, and I remove the bandages going to go back over 2 spots that i haven't pulled anything from close to foundation as its an orchestra of iron , Gonna concentrate on an 8x 10 square and go slowly , I have all the patience in the world when theres a chance to unmask keepers. its funny I had some time yesterday and decided to reread through Manual and they advise it also on P-17
Thank you

My advice on keeping the sensitivity high was for deep targets. If you lower it too much, you won't even get a response.......good target or bad. I'd rather hear whatever it is and filter it through my brain.

My concern is not depth , my nail beds are shallow with alot of iron masking and falseing on bent nails and square nails with round swells of encrustations

I was just wondering if anybody actually put in to practice or tested what the manual advises in two different pages



& also as I read tests on tests with other machines

I'm just guessing here but are you asking about the Nox

I hear you, I prefer to hear it all too, but when you are dealing with a bed of nails situation (the OP's scenario), depth really is somewhat irrelevant and the close proximity of iron can mix with the non-ferrous target signals and overwhelm or distort the detector audio and target ID. Lowering sensitivity helps the masked targets to pop out of the ferrous muck.

Haven't tried it yet with the Nox but when using the X-Terra 705 in heavy iron nails I like to notch out the most offending iron number (ie the one that pops up consistently). Then using the amount of nulling in the threshold as a guide, drop the sensitivity accordingly to reduce the blanking to an acceptable level. You can use other clues but this works the best for me.

On the Nox, instead of using the horse shoe all metal accept feature you will have to accept all iron numbers using the notch accept/reject which can be done ahead of time.
The nice thing about this method is that you can ride the sensitivity, raising or lowering it based on the amount of threshold blanking you are currently getting as you work along.

Thank you Tom

I will give that try also

I just had to run 15 in a section of a lake I was hunting.

[Wild Colonial Boy]

How did it go?
