Some info about Tesoro Compadre Coil

[Equin]

Hi,

I decided to modify my Compadre and add coil connector - mostly because of this annoying assembling procedure (I like to put my Compadre in backpack) when you have to turn whole pole trying to wrap the cable around it. I tried to find original Switchcraft connector but had no luck, so I used regular Radioshack 4-pin audio connector. It works fine, but when I touch its metal body Compadre beeps, so it has to be grounded to avoid this noise. After grounding it works well.

Just in case I measured this original Compadre's 7" coil and data was slightly different from standard Tesoro coils published on this forum couple months ago.

My Compadre coils has:

TX: 5.64 mH, 20 Ohm
RX: 5.88 mH, 30 Ohm

RX and TX coils have common ground (RX- and TX- wired togedher INSIDE coil body), so all these discussion about "if schematic with grounded Rx is wrong" doesn't make sense

Re: Some info about Tesoro Compadre Coil

No, because the place where the two RX- and TX- are connected together is very important !
If it is in the coil body, it is not the same as being connected on the PCB !!
The behavior is completly différent !

Re: Some info about Tesoro Compadre Coil

If I am not mistaken the Compadre runs at 12khz and not 10khz like the majority of the current Tesoro detectors. This would explain the differences in the coil readings. It would also suggest that the Tesoro Tiger Shark Coils (which is also a 12khz detector) would probably work just fine on a Compadre.

No, Compadre coil is standard 7''Round which can be used with Micromax models and vice-versa.

thanks mike. really THE re-discovery... the much time repeats is THE MOTHER of a learning (c).

Could you repeat to me please the schematic of a good tesoro coil ?

thanks ! I still have some difficulties to optimize it precisely

new release of Ciklon




hi tesoro mMax lovers,
I do not have a schematic of coil. sorry! I think it's very standart planar coil many times discussed in the forum.

WHAT i CAN really:

I can give you new schematic of ciklon. it was been made of him and working. it has an autotuning GEB feature and adaptive channel. absoliutely new release!

sincerely yours, kt315

schematic of a coil




i take it from Ivan Kostin's site...

Re: new release of Ciklon : schematic don't display???

Hi,
the schematic don't display: perhaps too big file???

I have made an eliptic coil with this principle this WE !, and it is working ! Just few centimeters missing because the phase difference it 180° instead of 90° , still to be optimized
