Many years ago, it was reported during discussion on another forum? about the Explorer being able to register a non-discriminated target during a null. Only mentioned this as during some testing with the Sovereign I've bought, the recovery time seemed to take forever. Ok I was using a Tornado coil and the particular patch I was working is really bad as regards iron, some nulls would last a swing and a half or more. It was on the way home that I remembered the comment about the Explorer. Any thoughts?
