Whites Coinmaster Classic II Coils

[geoscash1]

Anyone here know what coils will work with this unit, I'm lookin at pickin up a blue max 950 deepscan 9-1/2" coil, will it work with the classic II ?

Thanks for any help or replies in advance..

I'm not a Whites Expert but like many other brands, it not easy to find ANY other made coils, there will work.
If its any help, I got a brand new NEL hunter coil (COINMASTER 8 khz) I did buy to a test. I could measure the Inductance, resistance and resonans If you need. This Hunter coil I will try to sell anyhow. (Its without the plug a the moment, so its easy to measure it).

you need 6,59kHz coil. all those are compatible. MXT, DFX coils are NOT.

Ok, thanks guys. I appreciate the replies..

Hopefully Carl can confirm this as I ripped this from another forum

Not mentioned but I believe the original Whites Classic that used 2x PP3 batteries used a slightly different coil

And the 8x AA battery pack works okay with the blue max 950

----------------------------------------- ----------------------------------------

Go to any forum, chat group, etc., and you're bound
to see discussions about using this coil or that coil on this
or that detector.

Well, just because a coil is round like your coil,
or has the same connector like your coil, IT DOESN'T MEAN
THEY'RE COMPATIBLE!

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 loop
is 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 units
may or may not ground balance properly (even if re-adjusted),
but disc settings will be off and target ID's will not be accurate!

wow, big thanks Koala,

That was perfect.. I searched whites forum and a few others yesterday for more info but just wasn't finding what I needed. That quote pretty much explains the whole ball game..

Much appreciated, it just saved me from buying a Wrong coil, almost bought a BM950, mine has the 6b designation..... what forum did that come from?

here

Would like someone to comfirm this as it's the only place I seen it

[geoscash1]

Thanks Koala, I searched all over that forum yesterday but was searching "classic II" and "coils for classic II"..... I see that was in a thread about the 4900, its tough finding stuff sometimes...

I thought an idx or idx pro coil would go on a classic

eah classics and idx for whites are not exist =( http://www.whiteselectronics.com/sea...tibility-chart

Think if the Classic coil was the same it would be on the list for the BM950 as it would equal more sales

We know that the BM950 can be made to work with the homemade IDX is that because it has an external manual ground balance and the difference is in the phase.

If it is phase I take it it would air test great but loose depth in the ground and false more.

I am curious and would like to know the difference and can they be made to work properly via an adjustment

Confirms that they are different only Classic III Plus, ID, and IDX, can use the more modern coils. Since the Classic SL 1,2 and 3 share the same PCB as the IDX then it can only be a jumper, component change or adjustment

i have a whites 3900 pro plus, and the only coil that works on it is the one it came with, even though other 14khz whites coils are said to work they dont, which is a shame as i have wanted a 6" coil since i got it.
the internet says that the 3900 proplus is 6.59khz, but this new commercial uk only version i have is 14khz like a dfx.
so there seems to be a difference between 3900 models.
