<i>I wrote Minelab and asked about channels. I bolded the most important part of the message. Here is the response....</i>
Thank you for your questions. I understand your confusion and will try to explain what is happening.
As you know, when the Explorer is operating, it is scanning in 28 frequencies. These frequencies are linked to each other by a number. People used to Physics or Maths would call these numbers 'fundamental frequencies' and what we commonly call frequencies they would call 'harmonics'. To give you an simplified example that shows this ( the real numbers are a lot more complex), lets say that the fundamental frequency number were 1.5 then the frequencies or harmonics might be 1.5; 3; 4.5; 6; 7.5; etc, if the fundamental frequency number were changed to 1.4 then the harmonics might be 1.4; 2.8; 4.2; 5.6; 7; etc and if the fundamental frequency were 1.6 then the harmonics would be extrapolated from there.
When you do a noise cancel, the detector scanns through a series of fundamental frequency combinations to choise the set of harmonics that are the least effected by other interferance in the area. Likewise when you manually select a channel, your just selecting a combination of frequencies that will be the most stable.
Please disreguard the numbers used above, I only used simple numbers like that to make it easy to understand, in actual fact the numbers are a lot more complex but the important thing you need to understand is the the degree of movement between the fundamental frequencies used in each of the channels is very minute and <b>in no way would it cause your detector to be more stronger in depth or sensitivity in one channel or another.</b> The only difference you'll notice will be that some will be more quiet than others in certain environments on certain days.
