WHY 20 1/2 AWG Wire?
I got a good deal on the price of this wire, But its also a Good Size for this application!
However, I also wind coils with 20, 21 & 22 AWG, Depending on my current stock situation.

Why the 400 uH?
It appears to be a Good Value for general detecting.
Reducing inductance values does NOT increase my prices above, If so Desired.
(In Doing this, The Outer Diameter will stay the same but the inner diameter will increase somewhat.)

Note:

1) All Coils are Epoxy Coated, but they should be further mounted on a Rigid Surface or in a Suitable Casing.

2) Each Coil will have the Number of turns Printed on it as well as the Measured Inductance.

3) Postage Costs Will Vary, depending where you live!

4) Orders recieved from "Outside of Canada", "May be subject to Duty and Tax" as Might be Imposed by that Countries various Customs Officals!
Sorry, I have no control over this and I do not want to get in trouble with the governments involved! But usually this is only a few dollars at most!
