Sensitivity question...

[Anonymous]

I was just wondering something while wandering around listening to the iron today....
If I set my sensitivity to Auto 22, keeping in mind that in Auto the machine has a 'mind of it's own'... will it only fluctuate to the upper limit I have it set at? -or- If conditions warrant, will it override my setting of 22 and raise to say 30?
I know about it possibly overcompensating and the resulting setting may be drastically reduced in certain conditions but am curious as to it going the other way.... or do my settings in Auto not matter at all?
Any ideas?
Thanks
Tom

Thomas, no it won't override the 22. In auto you might aswell run 32 unless it gets a little chirpy in heavy iron from the detector no resetting quick enough.

Hey Tom,
In auto it will adjust the sensitivity UP or DOWN. Drop the sensitivity way down to 1 and switch between semi and auto. Auto will be much deeper.
The general consensus seems to be that in Auto mode the explorer will drop the sensitivity too low in trashy areas. However many hunt in auto almost exclusively and still do well.

Hi Chris,
I hunt almost exclusively in Auto and I do well. I've tried manual at different settings [usually 22 - 30] and go crazy with falsing. High 'Manual' settings also seems to give nails and other iron a trailing high pitch silver tone which fakes me into believing there's a coin down there with it. If I do use manual then it's usually set between 12 and 22 depending on stability.
My question should have stated:
If I use Auto, does the maximum manual setting matter? Say I'm in a perfect site. Ground conditions are excellent. I manually set the sens to 3 - I assume Auto will disregard my 'idiot input' and crank the sens up to 32....
Trust me, I make life so complicated sometimes.... <img src="/metal/html/lol.gif" border=0 width=15 height=15 alt=":lol"> I wonder how I ever get out of bed in the mornings...
Thanks for the response Chris
Best of luck in your hunts

Hi C.
This site is soft loamy soil, lots of sand and old rusted iron. No electrical interference ['ceptin solar -if ya believe in such things <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=""> ] but I can't get more than maybe 22 without a whole lot of extra chirps and irratic threshold. I tend to go with Auto and let the machine do its thing. But if I set sensitivity at say '3' I assume auto will over ride that dopey setting and crank itself up to whatevers stable for the conditions. [??]
Same site different day... I have to drop it to around 12 to 16 to keep it stable. <img src="/metal/html/confused.gif" border=0 width=15 height=22 alt=":?">
Gotta send the machine back to Vegas this winter but like I told Chris in the previous response
I like to make life waaaaay too complicated... <img src="/metal/html/grin.gif" border=0 width=15 height=15 alt=":grin">
Thanks for response bud and great finds on the main forum!!!!!

Hey Tom,
If you explorer is going crazy in manual but not Auto it means the explorer has dropped the sensitivity below that setting. If you can run stable at 12 manual it means in Auto the explorer has turned it down to that point, possibly even lower.
If I understand life correctly, the explorer in Auto strives for stability, and will lower the sensitivity until it gets it. In trashy areas it can often mistake all the targets for noise and drop it farther than most would like. Not sure if this holds true for all trash or only iron.
I'm not sure how far from the set point the sensitivity gets changed in Auto, some have said 12, others 16 or more. I played around abit listening to noise levels and guessed around 12 also, but a it was a fairly subjective test.
So if you are Auto 32 and it varies 16 you would at worst be equivilant of manual 16, at 24 to could go as low as 8. Actually heard once that if it is set higher that 16 it will vary between 16 and 32, less than 16 it will vary between 1 and 16. I'm not sure which is true.
But I do know it doesn't vary full scale. If you are in Auto 32 I don't think it will go to 1. I have found places to noisy for Auto 32 but was able to get it to run stable at a lower level.
So to answer you question. It doesn't matter hugely where you set it.

Just a thought,
maybe it might help if the Explorer 111 when it comes out. Displays the sensitivity setting it is selecting in auto, it would be a good visual idicator to the type of ground your detecting on, & a comparison to what you think is the ideal setting in manual could be made.

I have seen and tried a few things with my Explorer and I will not run semi auto 32 anymore unless completly trash free, maybe semi auto 29, but not 32.
I had a chance to detect where a old sidewalk was being torn up and run semi auto 32 and it run so smooth I couldnt beleive it. I like to check signals on a dime in many places, so I threw down a dime on the ground and got no reponse on it, so first thing I thought I left my probe one, but it wasnt. went over the dime again and I couild get it if I was touching it, took it out of semi auto and it just chattered and nulled, so I droped the sensitivity to 25 and went back to semi auto and now i could get the dime even beter with lower sensitivity and could get a good 3 inches of depth from it. Manual was too noisie so I dropped it down to 16 manual and got a good 4 inches on the dime and semi auto the same.
There was so much nails and other trash there that the higher semi auto was over compensating the sensitivity to run a smooth threshold I lost all depth on a good target. I may be wrong, but feel the higher you set the sensitivity in semi auto the more it will over compensate to run a smooth threshold and loss of depth. I have done several other test like this in the feild in trashy area where i will put a dime on top of a null and notice the higher I set my sensitivity in semi auto the more depth I lose and around 23-25 manual or semi auto are about the same.
I now run semi auto at 23-25 and if it is running to quiet I will switch to manual and if still very smooth I will up it in manual untill it will be unstable and drop it a little. If switching to manual from my 23 semi auto and it is unstable than I know I have to drop my sensitivity a bit or switch to semi auto. I have had areas where I can run 30-32 manual and others where 16-18 is about as high as I can go.
