Rarely used 6"@14 kHz coil covered with stone protector, this coil requires no cover. I haven't been using it more than 2 years since I attend super trashy sites very rarely + my grounds are light/extra light and I'm switching to very high frequencies. There is a thread "Sniper 6" DD Coil for Trashy & Super Trashy Sites" entirely devoted to this coil, running particular 14 kHz frequency. It fits AKA Signum MFT, AKA Signum MFD, AKA Sorex Pro, AKA Berkut 5.
Payment via paypal (personal payment). Price includes free shipping (EMS Post) and no shipping insurance.
In order to avoid customs formalities at destination, coil could be declared as a "gift"
