Here's a suggestion:
On page 224 (TX Circuit) it is mentioned that R21 (10k) could be replaced with a multi-turn preset in series with a 4k7 resistor. This will allow the TX frequency to be adjusted, which will then change the sensitivity. If you do this test with a new set of batteries, and make the TX adjustment so that the meter does not have an offset away from zero, then the voltage regulator may not be required. Alternatively you could add both the regulator and the TX adjustment preset for greater flexibility.

Hi Dear Master Qiaozhi
Is that you solve the problem ? for the totem works in all countries of the world.
Maybe you're right for your setting.
I also 2 years before I encounter this problem. but I solve this problem . I found a good method to cancel the effect of the compass.
I suggested a frequency that varies between
30 to 75 kHz adjustable to calibrate LRL in any
region of the world in a split second if this problem is encountered .
Dear
Morgan I am with you when you go down on the earth to locate a treasure fled the frequency goes completely .
Directory you can watch here is my little video with a mobile phone by a friend during our experiences of my LRL .

look here is 59KHZ and Goes 1KHZ and 0KHZ when touch Ground

But in compass rest and also increases
Note: I am against the electronic swivel but my friends think otherwise hihihih
but even as it rotates. this is a first experience for 3 years beginning
Thus a buyer of my LRL has found gold and silver together in a tomb . a near distance a bit long 600 m and a depth of 1.80 m
Dear Qiaozhi to help
Goldmaxx to cancel the detection of the compass using a capacitive or resistive potentiometer to find the right frequency in his country.
I do not know his country to help . because I can define the frequency by my caluculs . and the experience of my buyers LRL . I want to thank Williams for his LRlman table definition of frequencies .
And thanks for
FrancoItaly for their attention to the effect of the compass. but it must neutralize adjustment of frequency.
Waiting for your good news dear
Goldmaxx
