How do YOU set your sensitivity ?

That question has alot of variables, the coil you use, the ground you are in, EMI (Electro Magnetic Interference)
For me, I use the SE w/ the 10 x 12 SEF and can usually run it at 26 semi-auto or better.
Friday evening I was at 32 semi-auto and it was very stable.
Now if I am using my 6" EQ2 I can usually max the sensitivity. I rarely use a Manual Sensitivity because I am very happy with the depth I get in Semi-Auto.

Do a search on Youtube for DesDunne1 and you will see a very good suggestion for setting sensitivity. By doing this you will better understand how important it is to be sure you are not pushing the sensitivity too high. I personally think that having it just a little bit too high will have a reverse effect on the Explorer's ability.
For me I start at 26 semi-auto, after a short while if I hear thumping and erratic behavior I will start to lower my number with the coil setting on the ground until the erratic behavior stops. If you don't do this it will be very hard to find anything.
Don't let a low number scare you into thinking that you are not getting good depth. If you have a stock coil or an aftermarket of proportionate size you will still have very good depth at 20 semi-auto. One thing I suggest is make sure your gain is at 8 or higher, 10 will ensure you don't miss out on the really deep ones. Now if you move out of that area away from any overhead power lines then go ahead and try and push your number higher.
One of the ways I can tell what kind of depth I am getting is just by looking at the depth meter when I go over junk targets.
Hope this helps,

Those are two different things.
As far as Sensitivity:
I let the ground conditions (mineralization in the ground) dictate what my settings will be set at.
If I can get a semi stable threshold at 29 Manual then by all means I will run it BUT, if conditions only dictate that I can run 18 Manual then that is what I run.
How do I determine that?
I like to run it up until it gets chattery then back it down until its a steadier threshold. I can deal with a Lil chatter but, too much is not good.
I try to always run Manual but, that is going to keep you there at that given amount of Sensitivity where as Auto allows the circuitry to adjust to changing ground conditions.
Why, do I do that?
I can tell allot about the ground conditions as the chatter increases and decreases. At that point I can easily raise or lower my settings as I see fit.
Is Manual the best way to go? Well, that is open to debate as some would rather let the machine pick the Sens. but. I would rather know more about the site and then adjust accordingly as ground conditions change.
As far as EMI:
That is what Noise Cancelling helps to rectify.
I try to use Noise Cancel every time I arrive at a new site. I often forget but, trust me you will know if you have any EMI and will quickly reach for that Noise Cancel button..
Then, if that fails (which rarely happens) I will often switch and see if another Channel is less prone to to that EMI and quieter. On rare occasion that works but, not very often.
I deal with interference problems quite often as I hunt with another EX user often so, switching channels or noise cancelling is almost always a given if hunting close by.
Also one thing to keep in mind is if you rely on the screen to give you an ID on a target you need a threshold before one hit to another for it to ID properly on the screen. To high of a Sensitivity can result in no Threshold so, keep that in mind.
That is why to high of a Sensitivity can be a serious problem for those that rely on the Smart Find cursor placement as to dig or not.
You might also check out the "Explorer Classroom" for great information on settings and advice.
Remember you will set your Explorer for what suits your needs, hunting conditions, what you hunt for, and etc. so, what might work for "one" is not a given for the masses.

I just got my Explorer SE last week and have a few days use so far. I don't want to high jack this thread but according to the manual you can set the sens and use semi auto and the machine will try too maintain that setting but adjust for the site.
So why not set it at 32 and let the machine compensate?
Could you expand on the thumping sound, I'm pretty sure I've heard that.
Thanks

The thumping sound is caused by EMI, the manual is right if EMI is not present. If you are around power lines you can start off with it set very high in semi-auto but shortly into detection your Explorer will become erratic because it try's to push the sensitivity too high. This is why you must back it off. Watch the video and you will see Dese need to back it off to 10 or 12 which to me is extremely low, much lower than I have ever needed to. The newer coils handle the EMI very well.
I completely forgot to say always try noise cancel, sorry it's such a habit of mine that I totally forgot. If the EMI is too bad though a noise cancel will not fix it, only by lowering the sensitivity will you remedy it.

Sometimes you can over-analyze bud. If you're hunting in conductive tones and some iron mask as most people do then you will get some nulling no matter where you set it at. I think Bruce hit it pretty well with his post...just switch to semi auto. It will also make your machine seem more stable in high EMI areas.
Its a quick and easy switch...and even if your machine is nulling you will still hit good targets.
Back to your question at hand...yes I judge my sensitivity level by the amount of falsing...but not by the amount of nulling... for the reasons I explained above.
Semi auto will still go deep as I have seen Bryce hit many 10"+ coins over the years at semi auto 26.
