I own a CTX3030 and two of my friends that go hunting own the Explorer 2 and SE. Yesterday we were out in the fields and one of them tried to turn his SE on. The moment he pressed the ON button his phone rang and when he answered it the detector went all nuts playing all kind of sounds. He then tried to noise cancel the detector and immediately the Explorer 2 became the same thing. Mine didn't get affected in any way. WHAT HAPPENED??? Why didn't mine get affected???
