Good tip there Ironsight I will have to try that out. I usually just hunt in Auto+3 myself. I had an Explorer2 didn't quite understand it but at factory setting auto sensitivity at 16 which is the middle of the range but factory setting and supposedly the machine would adjust it up or down I got a barber quarter on Fathersday 2001 at about 10-11" according to the almost buried depth guage on the machine. I realized later my soil is 85-87 mineralization high around here and that is why that machine was "noisy" to me to hunt with. Once I read about how to set the sensitivity according to Des Dune video manually for my soil to run it quiet it ended up being 11 then I put it in auto and detected quietly with it. Makes a difference doesn't it. I have a corner of a park that I hunted with the Etrac and in Auto+3 and it generally runs at 15-19 and as high as 21 so I should try to run Manual at maybe 26 and up if quiet and not very noisy or else it may be too high and see what may be there deeper.
Want to clarify that maximum manual sensitivity to me means the highest manual setting in a particular soil which basically stabilizes the detector with a false or two maybe every couple sweeps which for me is tolerable. Cranking up the man. sense higher than that will increase annoying falsing noise and sloppy IDs possibly leading to missed deep targets.
Having said that, in areas where i know there are foot+ deep coins i will increase the man. sens. even higher than mentioned brain filtering out the falses best i can and hunt by tone, depth gauge, ID which is typically unusably jumpy and the all important dig or not instinct in that order.
Not sure what you're saying regarding Auto vs. Manual sens. Its important to know Auto and Manual sensitivity are related but not exactly the same.
Keep in mind the eTRAC uses 3 sensitivity channels to detect soil mineralization. These channels can have different sens. numbers depending on the soil.
Auto self adjusts the final sensitivity to the 'average sens.' of those 3 channels. The left sens. bar is the reading of the highest sens. channel while the right bar indicates the 'average' of all three channels which is the final sens. setting.
In manual sens., all 3 channels are unconditionally set to the same sensitivity which is why manual sense can be noisier but deeper. Here the left bar is the user setting while the right bar indicates the suggested setting for that soil. The right bar is the sens. setting the detector would use if it was in Auto.
There are trade offs on whether to use Auto or Manual sensitivity basically quieter more accurate IDs or deepest seeking with noise.
Your choice. :thumb up:
