Got this info From Allen Casey...............good info to have
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 (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 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!
Hope this help others as it helped me on figuring out which coil works on which Whites !!
