If you had asked me in 2004 if there was a good cross over detector for gold and CRT, I'd said no. Today not so much so. There are a few viable X-over detectors out there but make sure you are choosing what you need. DO not go detecting wondering if you made the right choices especially when your in the field. That is not the time to be questioning your detector.
THIS IS A NEW Podcast. Sorry for the confusion in the episode numbering,  Mr. zero and one's Producer had his zero and one sensibility rattled that I changed the episode number to match the QT and not the layout. :-) He won.
