Detector(s) used
TIME RANGER CZ3D ACE 250
I read someones post that said running high sensitivity would cause a loss in depth . I thought the reverse was true ??

I also read that a deep coin would null a lot of times because of depth . If this is true when my machine says deep target & nulls it could be a coin .

Your thoughts please .

Depends on targets and conditions.

Ever notice you can understand the words of a song better on the CD instead of sitting on front of the speakers at a rock concert? Or trying to read a book a 75 watt bulb is better than a 250 watt bulb when the lamp is right above you? The right amount of sensitivity is better than too much or too little. We're using inky dinky gozillionth of a watt transmitters and power is not the name of the game. Finesse is.

Too much sensitivity makes the soil itself look like a bunch of good targets to the detector. It gets all excited and gives false signals, so you don't know the good from the bad. It also overreacts to iron, and can discriminate out better metals because the iron overloads the processor.

I have read that the Sovereign GT will null on deep coins.

Too much sensitivity has the electronics "see" the minerials in the foils field easier and it could hide a coin. A lot depends on the amount of matrix. If you slow down the sweep too much, the detector will null out on a deep coin.

The Sov. GT requires a slower sweep speed to process the info it gets from the coil and doesn't null out on a deep coin but assigns a lower tone to it. Read CJC's books on the Sovereign GT and Excal.
 
Another thing that comes into play is the operator. Short of actually overloading the receiver circuits, running super high gain (noisy as hell) will generally give better depth and sensitivity to small targets.. it's just tiring to listen to. This is how many a nugget hunter runs the ol' detector. ..Willy.
 
also it will pick up "peripheral" targets on the fringes of the coils detection range(choppy interference)
which i find distracting

Can you give me a little more information on some of these books? Although I have become a little familiar with my GT, I never pass up a good opportunity to unlearn my mistakes and get some tips from the Pros ;)
