I don't post here like I once did but rest assured that there is no other forum that compares to the wealth of information for Explorer users that can be found here on Findmall.
With that said, after reading 5 pages of post concerning all metal (wide open IM ) verses discrimination and hearing targets sound off during a null ... I decided to post my 2 cents worth.
Nulling is simply the result of a software driven discrimination process controlled by the amount of discrimination being used.
The higher the discrimination, the better the chance for nulling between ferrous and non ferrous targets that are co-located.
The detector still hears the discriminated out target but turns into a defaulted null sound to your headphones.
Granted ... good targets within the nulled targets will sound out when hit at the right angle.
Wide open iron mask allows for a much quicker re-set time between co-located targets and you never hear a null ... but it takes quite a while before the brain just ignores what can drive most others crazy. So ... wide open IM is not for everyone but neither is disc, I tend to trust what I hear and let my shovel do the rest.
Whatever works best for the individual is all that matters. I prefer to hunt with a wide open IM screen and hear it all, I'm used to it and can cover more ground that way.
Since I mostly relic hunt, iron is my friend, when hunting LARGE open fields or I'm way out in the woods and suddenly come up on a bunch of iron ... it tells me that PEOPLE were there and to sloooow the hell down and investigate the area more.
The old timers (me included) used to discuss the MInelab Wiggle here quite often, the process doesn't care if the detector is in all metal or discrimination mode ... all that matters is that the user can approach a target with shorter and shorter coil sweeps until the coil mimics a WIGGLE motion right up on the target. This was discovered many moons ago when trying to WORK up a weak signals on the edge being detected and we found that it worked quite well with close co-located targets too. Many dedicated Sovereign users can attest to this as it seems that this process works best with Minelab multi-frequency detectors and I've rarely been able to duplicate it with other brands including dual frequency units.
I can't tell you how many good targets I've dug over the years that only sounded off by just hearing the threshold sound make a soft dip ... that's it... just a dip in the threshold, no screen movement, no low or high sounds ... just a dip ... dig down a few inches and the screen and sounds start producing results.
So ... my opinion on all of this is to use whatever settings work for YOU with time spent in the field detecting. There really is NO shortcuts unless you are lucky enough to have Explorer mentor as you learn.
But the bottom line is that this is a HOBBY and we are supposed to be enjoying it
Hope nobody takes this post as offensive ... it's not meant to be. I'm just an OLD guy that likes to ramble sometimes.
Good Hunting
