Took 3 yrs to get permission to hunt a 1700s church that is on historic registrr.... Only to have the adjacent property owner, after swinging for 4 hrs, tell me that there has been detectors hunting it for 30 yrs... Took the wind out of my sail. Nevertheless, the CTX only picked an IHP from the site. I really expected more from the site and certainly the CTX sniffing out what other sub standard machines missed... No magic to it. If a sites been hit hard, the score ratio goes down, regardless of CTX or not.
