Aaron's (local_coins) post of April 21, 2006, titled
"Ace250 Depth Tests" caused me to ponder the
relationship between the Ace's sensitivity settings
and depth-indication scale. (See our forum board :
Detectors and Gear and forum "How to Use
Your Metal Detector".)
The purpose of these Depth Tests, as Aaron explained to me, was "to see how each reduction in
sensitivity (From 8 max. to 1 min.) affected my depth." He included a very nice chart showing results
of tests.
I wanted to refresh myself on what Garrett had to say about Sensitivity in the Ace Owner's Manual.
On page 10 the manual states "Use higher sensitivity
levels when searching for very small or very deep targets. Use lower sensitivity levels in locations where the detector is behaving erratically due to excessive metallic trash interference, high mineral soils, salt water beaches, or other metal detectors are present."
I read a post somewhere in FMD forums quite awhile
back that said the user always ran 8-bars max., and
only reduced it if there was excessive interference.
Others have settled on 5-bars as a regular setting.
My question follows: While we can speculate on what
type of targets there might be in certain areas and at what depth these targets should be, we really
don't know (type or depth) for sure, unless we have previously worked over every inch of a particular search area......and I doubt that anyone of
us could make this claim in all honesty. So, wouldn't
it be best to begin each THing session with sensitivity
set at the max. 8-bars and only reduce if necessary
due to interference, erratic operation of the machine,
etc., etc.? Who knows, that special find could be just
below a sensitivity setting of, for example, 5-bars
and you walk right over it !!
Advice and opinions are welcome !
