Rate my Discrimination pattern

It's been a long time since i was out previous to Sunday there. So kind-of forgotten a lot of stuff. Was using this pattern, basically the default nails pattern but a bit more. What are peoples thought? Would you do something different and why? Many thanks.

P.S. Yes sensitivity is at 1, because I'm playing with it in the house.

whats your sensitivity set at looks way too low :-/

:-/ Ummm what are nails ? Would I do anything different ? yes call a dealer and trade the lunch box in for a Deus .............only joking ;))

Good to see your back OooO

Have a look at this video, I recommend the settings used, speeds up the explorers recovery time and running it flat out with no discrimination is the way to go. If you like it a little less mental you can put a tiny pixel on the top left of discrimination, but I find even that causes the "nulling out" and every time it "nulls out" on your swing, your potentially missing targets.

Yeah, thing is, I like a really slow, quiet type detecting experience. I cant abide lots of noise and like a relaxed style of detecting (even if that means I miss some targets). Unusual I know, but its my style. (I would rather get 5 signals in a day and two of them be good than get 500 signals a day and 10 of them be good). I guess for me, metal detecting is a way I wind down, relax and get away from it all, its partly about just wandering around and enjoying the views. Im not a "serious" hunter who must irk out those faint signals lying next to Iron. The actual setting on the detector are factory set all be it with Deep ON.

Just wondering about the descrim pattern really. I never dig junk iron with that but want to make sure im not missing wee half hammies or anything.

Thanks.

In my humble it goes to far to the right at the top. You are getting into missing "big" high conductors as the target seperation is fallible.

Personally I can`t see the point of any discrim ,barring you wanting peace & quiet, I would run in all metal & listen to the iron, if you use headphones with volume control it can be managed.

Nulling misses targets and a multi frequency, multi tone machine works better with everything functioning.

7.5/10. =))

Thanks, thats suefull info.

I did previously have it slight less discrimination (smaller triangle). But I sometimes found iron clipping up just here

So notched out a little more.
But I will remove some discrim and see how I go. Thanks.

I would use the smaller triangle & your ears/tones for the iron that falls outside, even removing a spit of soil will allow the machine to do it for you.

And if you go down the "small triangle" route then you might as well not lose any detecting "time through nulling" and detect in all metal. ::g

I use just 1 pixel of Disc top left. I do get caught out by rusty nails occasionally, but only the bigger ones when they're lying flat in their backs.

I can`t see the point of even a sigle pixel of discrim as the null/recovery means you miss more potential "near iron" targets.

Better to hear the iron then pick up the "dodgy" signals nearby.

However its purely personal. ::g

I'll give it a go JCM.

Do you dig many iron nails?

I totally agree JC - some fields I search are absolutely littered with small iron, causing the almost constant "nulling out" It was only recently that I realised whilst the explorer is "nulling" it won't pick up any other signals. God knows how many hours I wasted before I realised this, all that time swinging and not hearing anything. In my view the explorers biggest downside is the slow recovery speed, even in all metal you still have to keep the swinging slow, but when you get a good target in all metal and full sensitivity there's no mistaking it. I'd rather have a a noisy time and be sure I'm not missing anything, finds are rare enough over here on the IOM without me making it harder for myself by using discrimination. The only other downside when running in conductive tones and all metal, is listening out for the high silvers (the big milled) as the high silver tone is similar to the high iron tone, but you've just got to watch out for the "flutey" high tone rather than the "sharp" high tone. The smart find window does help, but I find it really slow in reacting - does anybody else find this too? I really only use it for checking the dodgy signals.... if it flicks into the top left iron section for more than 50% of the time over the target then I leave it, I still occasionally dig these just in case, and it's not been wrong yet (i.e if it does flick into the iron section, it IS iron!!)...I've never really used the "Digital" display with the numbers as I can't make head nor tail of it and the numbers are just constantly jumping around anyway.... :D

Interesting you should say that. I asked minelab this same question and they said it makes no difference to recovery whether your nulling Iron, or sounding off on it.
Think about it, the machine hits iron, makes its calculation that it is indeed iron and sends a signal to the speaker to either, make a noise (no descrim), or make no noise (stop threshold). It doesn't affect the machines ability to "recover" at all. It's not as if the machine is shutting down when it passes Iron when its nulled, it just switches the speaker off briefly rather than on.

The recovery speed is dictated by the speed at which the detector can process one signal to the next, not what signal goes to the machine speaker or headphones (which, incidentally happens at near light speed). Common misconceptions and all that.

I will counter with different iron tones & cursor behaviour.

Some just squeal in top left (on the SE).... shallow iron bits.... they are the "its iron" ones.

Others have a better tone but the cursor "holds" to the left about halfway, generally deep flat iron or iron chain loops.

Then you get dual signals.... iron with a "mumpphhh" those are the ones that are non ferrous very near iron. Often the cursor will try to pull away into the centre of the screen or towards the bottom right.

Holding the coil above these "dodgy" signals and shaking it side to side can enable it to lock on to the non ferrous, as can removing a spit of soil. Its so difficult to type descriptivly but so easy to demonstrate in the field. =))
