Greetings !

#1..Does the Compadre (5.75" coil model) have a concentric/coplanar coil ?

#2..Does the search coil include a TX, RX and a Bucking coil ?

#3..Can anyone provide a photo showing inside this coil and how the windings are arranged ?

Thanks,

the archive does not have a data on the coil but there are other data on tesoro coils.
i believe it is Tesoro concentric
Tx 1,5 5.7mH 22 ohms -- Rx 3,4 6.2mH 22 ohms

Tesoro Compadre Coil Type and Windings.

Hi !

Sorry I'm late reporting this; I called Tesoro on 5-19-2018 and was switched to Vince Gifford for answers to my questions and his answers are colored blue below.

Question #1...Does the Compadre (5.75" coil model) have a concentric/coplanar coil ? His answer was "Yes". (See definitions below.)

DEFINITIONS:
Concentric...having a common axis...Coaxial.
Coplanar...Lying in the same plane.

Question #2...Does the search coil include a TX, RX and a "Bucking" coil ? His answer was "Yes".

I've included attachments below to give visual and textual aids to help make the above definitions and understanding a "Bucking" coil easier. Vince prefers to call it a "balancing" or "tuning" coil.

Also, I want to thank Carl Moreland and George Overton of Geotech Forums for the attached paragraphs and the Fig. 5-20 photo which are shown in their co-authored book Inside the Metal Detector and also available to the general public as a pdf document on the Internet at :http://www.geotech1.com/pages/metdet/info/coils.pdf

The "Concentric Coplaner" photo I picked up somewhere else off the Internet, but don't remember where at the moment.

Hope this was interesting to someone.
