I dirtfish with a friend who is running a CTX with wireless headphones. When I try to hunt around him I get a huge amount of interference. He attempts to tune out my detector on his machine. I back off and try not to hunt closer than 15 yds from him and lower my sensitivity but it doesn't help much. I'm running a DFX which I know is real sensitive to EMIs. Could the signal from his wireless headphones be causing interference?
