Whites 6000 Metal Detector Coinmaster Technical Discussion. Electronics Related

[inductor]

hello,


i am looking for any information \ documentation on some older whites metal detectors.
i have a few units that i am trying to recondition and have found it hard to find technical information.


for example: digrams, the tuning pots on the circuit boards, wiring schematics, coil compatibility, pin outs, modifications, etc.


the machines i am working on at the moment are the 6000/D, 6000/D S2, 6000/Di S3
they all work, but there are a few issues i would like to figure out.


the 6000/D S2, 6000/Di S3 both have hip mount modifications which seems to be the main issue i am confused about.
the coil will plug directly into the machines or the arm rod, but will only work when plugged into in the arm rod socket.

there are also issues when interchanging coils between the other machine 6000/D. plugging coil direct will not work.
i have 2 whites coils marked (dark blue 624-0179 and light blue), but they don't interchange i am not sure why. they work on their own unit only

dark blue 624-0179 coil works on 6000/D S2, 6000/Di S3 with arm rod
light blue coil works on the 6000/D

i was able to get the light blue coil to work with the 6000/D S2 but the response and air depth was very poor in compassion to the dark blue coil


so i am mostly trying to understand the coil differences ,wire pin outs and connection differences. (red, black, white, green, shield) they connect differently with the arm rod
6000/D S2, the arm rod seems to connect from the detector to: red, black, white, green, shield, to its coil output socket is red and white to same on coil plug and black, green goes to a push button. and the rear of the output socket has black, green, shield tied together.

to simplify: red and white > red and white of coil / black, green > push button (not connected to coil or rod socket) / black, green, shield of coil all connect together behind rod socket.


any advice would be much appreciated.
i have some technical and electronics background.

thank you

i would also like to have further electronics technical discussions, if there is anyone interested in the subject

also: wanted : Whites 6000/Di PRO SL

Thank you for sharing these documents!

[inductor]

holy crap.. THANKS!
this will taker some time to go over, and has now overloaded my cranium

in the meantime if anyone has time to chat about the post please let me know.

[inductor]

from what i can see, if anyone can confirm?

RX is red and black
TX is white and green

its still very hard to see the construction and wiring inside the coil



but it seems the hip mount mod may work like this
coil red to socket red
coil white to socket white
coil black, green and gray all bridged together behind the socket

black and green wire to socket from detector to push button

so it makes sense that the
rx coil loop is red to black
tx coil loop is white to green

but what is going on in this config and why does it effect the working of mixing coils that should work on the 3 machines?

do you need white's' patent on coil?

[inductor]

hi kt315 do you have a copy of that book? and i think the file you posted has the patent or do you have it also?

the dark blue coil is marked as

6B 8-125
works on 6000D S2 and 6000Di S3



and

D4 ?
from 6000D




does anyone know the differences?

thanks

also found this info for anyone asking the same Q

Whites has used many different coil designs and windings over the years. While the housings and connector may be the same, the inside is totally different.
This discussion will focus on designs used in the last 20 years because there are still tens of thousands of 20+ year old Whites detectors in use.
The Internet has created many problems for detectorists. Most of the time common sense has taken a back seat to impulse buying, the thought
of getting a "good deal".

Look at the outside left ear of your search coil (where the bolt goes through it). You'll see a winding designation stamped into it, i.e. 6B, D5, G, 8B, etc.

D4 and D5 coils were used on the 6000/D and 6/DB detectors ONLY! They cannot be used on any other units.
The D4/D5 coils were available in 8" and 15" only.

B4 and B5 coils were used on the 4/DB and 5000/D detectors only! They cannot be used on any other units.
The B4/B5 coils were available in 8" and 15" only.

6B coils were in use since the "series 2" thru "series 3", Pro units, the Classics, and at present on
the Classic I SL and II SL. 6B coils were available in 4", 8", 10", and 15".

F coil was made only in a BM256 (Blue Max 10"). This loopis totally interchangeable with all 6B coils above. It was manufactured to give performance to units which use the 6B
coil similar to the BM950 coil is use today.

G, HI, 8B coils are known as the (Blue Max) BM350, BM600, BM5.3, BM800, BM7.8, Royal 800, BM950, BM1500. These coils are
interchangeable. THESE COILS ARE NOT MADE TO BE USED ON UNITS WHICH NORMALLY TAKE THE 6B DESIGN! TRYING TO USE THESE COILS
IN PLACE OF THE 6B COILS WILL HAVE VARYING RESULTS. Some unitsmay or may not ground balance properly (even if re-adjusted), but disc settings will be off and target ID's will not be accurate!

this chart seems to be incorrect.

i have tested the 4B coil on the 6000d s2 and 6000di s3 which use a 6b. its not not work.
and vise versa.

it lists the 6000d as a 6b. which what i have is not.

The loop guide chart does not agree with the info you show in post #9. To do so it should show the D4 (&D5) coils to work only on the 6000/D & 6/DB detectors, which has been your experience. The 4B coil you have would only work on the (not listed) 4/DB & 5000/D. White's has produced a bewildering array of search coils over the years. Some may work, with degraded performance, on other models.

i have quoted a few other posts, which agree with my findings that the chart is wrong. lesson learned i guess. triple check.
the 4B coil did work slightly on the 6000D s2 but the target response was very weak. any now i know why
