It has a self calibrating mode, and a indicator for mineralized soil.
But in the manual ist written that you can continue when mineral ground is detected it is no problem.

Yes i have the manual here.

In air i got good result for such a small coil, must see maybe i do something wrong while calibrating outdoor.

IT works also like a cable finder (maybe pinpointer) if you hold button 2 the performance is decreased 30times.

with my wet loam / clay ground in the garden
think it is e result of uneeficient shield grid (etched pcb shield)

More probable cause is inadequate GEB. Wet clay surely has GEB somewhat skewed against the ferrites.

have tested the pre sell version last weekend
is anyone interesed ....regards

Do you have an operating manual?

indoor in air it works good but on heavy wet ground ?

is anyone interesed that i make a special test / testobjects
distance test in air etc?

Aziz,
What is your opinion on INPHAN (inductive Phase Analysis) coil configuration
"INPHAN-Spulenkonfiguration"
"E-Faktor Vermessung MTC Sonde"

Note that the relative rotation of the two layers is not shown in Fig. 3 of the patent.

Hi mikebg,

I haven't looked at it deeply. I have absolutely no idea at the moment.
But interesting and novel concept.

That's really a nice (beach) detector. I like it.
The design is based on KISS-principle. That's another reason, why I like it.
And I like the "Switch on and go" feature with no fiddling on detector.

Well done to the designers.

Seems ok.

The fact the windings are crossed reduces the null by design/manufacture.

Id guess these dont need manually nulling in production. If true would save a lot of labour cost.


Ive been toying with adding a decent AGC to a Det receiver. I like the fact they use the Rx level to adjust the Tx power - nice touch.

Simply post in the forum the operating manual. Then we will think what to test.

hello

right got the mail today from that i will be available on store in march.

maybe i get a test piece this week.

some ideas what to test, or what you want to know about it?
