rangertell examiner field trials

Hi JP,

I hope providence ha been taken so that "detuning" will not happen again, or else it could be an endless story.
On the other hand, that would explain the apparent success of ebay business

Hi Fred,
I asked the Factory rep to personally test the replacement Examiner or have someone at the factory personally test it before sending it. I was told They will send a unit that has a fixed trimmer cap.
I presume this means the trimmer cap is adjusted at the factory to work for average users, and is somehow fixed so it cannot be adjusted to a different value.

Also, this time I will take precautions, such as not opening the examiner. This should eliminate any possibility of causing anything inside to become detuned or damaged after the Examiner arrives.
And with no trimmer cap to adjust, this leaves only three controls to be concerned about: The sensitivity adjustment, antenna length, and calculator key codes.

For an ordinary test scenario on a grass lawn or an open field, the procedure should be simple now. Simply extend the antenna by one segment, then enter the key code for the target you are searching for. And adjust the sensitivity before starting for the best response to the target. Of course there are other time consuming details to take care of such as bringing the test target items, the testing parafanalia, recording equipment, and checking the test area for trash that could cause a false signal. In spite of the time consuming details, testing should be easier than the previous attempts because we know there is no need to suspect a difficult trimmer cap adjustment must be made before the Examiner can become operational.

Best wishes,

If, rangertell, everyone can use, in a way
precise, measurable, adjustable.
if.
better, would have imagined.
Each device, unfortunately, there are weaknesses.
many, I used the device.
Most of the money trap.
(Through radio, out) $ 1,650
who make and sell on this site, these pages frequently writes.
Do not write a word of criticism badly.
A device with work, I think if you can get.
To critics, up to a point.
What systems of land, which the technology, to treasure the most information, data, gives.
bilgisi.olan experience for the open front.
A simple flip-flop circuit, + tip dipped into the soil, better than many MFD.

In this case, you will also need fixed humidity otherwise the thing will not work.

Can you elaborate?

Yes I can, but need detailed used calculator specifications first.

I don't think the calculator has a trimmer cap on it. Maybe it is not effected by humidity?

Esteban's battery. Without humidity, this doesn't work. Here an example. Voltage is zero (or not enough for to manage the fet) without the water. Also you can comprobe that a fet can work only with few milivolts and obtain very noticeable signal. Maybe in the soil the good conductive metal show this process, in consideration humidity of the soil too.

In the diode question thread I notice that with 4 Ge high quality diodes in serie can amplify big. Maybe this don't have relation with this theme, but... sorry, I have strange ways of seeing things. I save the old parts of the experiment, you can see below the schematic.

Hi Esteban,
What was the reason why you built this battery? Was it part of an experiment different than simply building a battery?

Not only battery per se. Wish comprobe is a fet can be supplied by few milivolts. And, of course, similar battery can show metals in soil.

Interesting experiment. You found that the moisture content would determine how much voltage could be detected from the battery, which could be used to extrapolate to how voltages produced by "ground batteries" can change when the moisture content of the ground is changed.
