11” DD Elliptical, Open, Accessory Searchcoil Item# 11COILTEK $199.00 MSRP
Note: Accessory coils carry a one year warranty.
How am to upgrade my coil if they won't fit the Delta 4000 you sold me 2 months ago? It has a push in coil plug. New coils are all screw type. If i have to buy a new detector to upgrade I doubt it will be a Tek.
