I'm a new CTX owner/user. North Central Arizona near Sedona. I've been detecting for years on and off and have owned Minelab, Garret and Tesoro detectors but the CTX is a beast. Not exactly lost (Andy Sabisch's book helped a lot) but it would be great to hunt one day with someone who's experienced with the CTX. I'll buy the beer after! If nothing else, when this post is old and dated and a new CTX owner is looking... get in touch, maybe I figured some of this stuff out and can offer help.
