Using Deep instead of General

Hi all,

Does anyone have a good understanding of when to use deep over General.

Does ramping up the gain in general equal running in deep mode?
I find the signal tone changes while in deep and i feel that i get more false signals is that normal?
Cheers
Marty

I call that switch on the front panel "the lazy mans switch". All it does is set the digital menu to predefined values for General detecting and for Deep detecting. If you want to know what the values are in both modes the GPX manual tells you exactly what they are. I prefer to set the digital menu myself so in that case it really doesnt matter which position the switch is in, your settings over ride it.
You will find if you switch it to Deep mode it inverts the signal and puts in Deep audio, thats why your tone changes. I have learned to use my own Deep settings when the ground gets deeper only, trying to use Deep settings when the ground is shallow does make my big coil more chattery and unstable, probably whats causing your false signals.

Also when using "Deep" on the front switch the tone for "FP" is 38 where as in "G" on the front switch the tone for "FP" is 50. So the combination of the inverted response and the 38 for tone make it sound much different to having it set in "G"

But you can certainly have any combination you wish in whatever switch you wish.

Very good explanation there mate with the "lazymans switch",
the thing with the GPX models is to get to know your machine better with the cause and effect
of the different settings for good/excellent performance, and sure, the pre-sets will get the newbies
running but they are by no means the best settings to use.

Its only when we start to play with the settings
"Manualy" do we get a greater understanding of the changes and benefits/losses of every little tweak we apply.

One thing installed in the GPX models i have never taken to is the "inverted" audio,MY reason for this is we have become
trained to listen for the raise in pitch/volume for a small shallow target and a "drop tone" indicating a deep/large
target, and i feel its very hard to re-train the brain to listen for the opposite response.

However i do agree with a lower "tone" setting for running a large coil for deeper gold,as also a lower
frequency setting for bigger "18" and over coils, and having the abillity to manualy set this in the GPX
models has been a great boon to finding bigger deep gold.

Large deep gold can at most times only give a faint waiver in the threshold so it is very important to
focus on your settings, and the main thing is a very smooth threshold, and doing a good GB, and if not 100%
happy with the GB do it again and again until you are happy with it, this allows not only a very smooth
threshold, but being able to notice any repeatable waivers in the threshold that can indicate a deep nugget.

One pitfall to many people tend to fall for in using lge coils for deep gold is to over enhance their settings
to get deeper performance, when it is quiet the opposite, let the larger coil do the "punching" and not the
"overdriving" of settings which will cause instability in the threshold and hide those very same slight murmors
that we need to hear....

Beepinpete, that was a great way of saying without saying what we all should be listening for, no matter what size gold your chasing, and no matter what size coil!
Set yourself up to hear, and you will hear!

Cheers.

Thankyou for the kind words mate.

You can lead a horse to water etc etc...
and as you prob know there is no defined "this is gold" target response that we can guarantee
is exactly gold.
I feel the one thing many newbies are lacking is the ability to problem solve
their own machines ability, its all to easy to keep on posting "help needed" posts and which
coil suits which detector in what ground etc etc, even a child knows not to poke the kitty in
the eye cause it scratched me last time, im not trying to be all funky here, but the makings of a
good detector operator are foremost the ability to understand the tool they wave and what works
and what doesnt work on the paddock.

maybe you can share some of your own findings and experiences/settings etc while hunting the holy YELLOW grail
as im sure the members will draw much from your help also.

As quiet a few members will know, i do like to help them get onto the colour if i can help, but i also like
to install within the hints and tips i may give some room for self reasoning, as i think this actually is more
of a help than just saying "go here and use this setting etc".....

Thanks for all the feedback on this topic, to beepinpete i understand your comments about knowing your machine but isnt a forum like this an aid to understanding your machine?
I myself have been detecting for 4 years and been succesfull and i do play and tweek my machine but as they say the more information and knowledge you gain the better. I have read the manual several times and do adjust and alter settings to learn so sorry mate if you think im not problem solving however no disrespect intended not all of us are blessed with your natural talents when it comes to understanding everything about these machines.

Cheers Marty

I used to say that you had to have the detector become part of your arm -- the feeling of being one with what was going on

Marty

Im sorry if i came across wrong man, as no ill intent was truly meant mate.

Thanks Pete,
