Got my replacement coils back today

[Schrecky]

Back on June 23 I sent my D2 and Super 12 coils back to Whites for replacement. Both of them were generating a lot of false signals and noise when the coil is held in the air (or on the ground) and softly giggled. They were making noise when they touched anything and also at the end of a swing. In addition they both also overloaded with RX=15 and TX B=on.

With my 9.5" and 5.3" coils I was not experiencing either of these annoying on going problems. They do not make noise when giggled or overload with RX=15 and TX B=on.

Today I received both coils back from Whites, it took 28 days. There was a note on the invoice that said "Replaced both coils under warranty. Both coils out of tune."

I took all four of my coils out to my coin garden where I have quarters in the ground at 7", 9" and 12".

Results using the Coin & Jewelry program with RX=8 and Disc=85.

Coil.......7"............9".............12"
5.3"....solid.......no sig.......no sig
9".......solid.......erratic.......no sig
10".....solid.......solid.........no sig
12".....solid.......solid.........no sig

Also, the only coil of the four that now overloads with RX=15 and TX boost "on" is the 12". If I turn the RX to 14 it no longer overloads.

NOTE: If I increase the RX and Disc settings on the tests above I can get much more depth out of all four coils, the three larger ones picking up the 12" quarter.

I hope that this will be the end of my coil problems but this is my 3rd 10" so time will tell.

My d2 falses only when I bump it on something. I have never had a big coil that didnt so I just have accepted it as the way it works. If it gets to doing it in the middle or end of my swing I will send it in.

Good luck. I'm glad you and Jack got them back. Rob

NOTE: It is common for DD coils to sound off when bumped, especially the larger coils.
