Question foTom

In the Fisher's world treasure news 2009 you did a article on the f75 and it was very good. And in there you said to run the disc. on 6 and monotone or disc. on o and multitone ( like 3 or 4)( bought setting notch on 1) for getting the most depth. I tried them and they work good. So my question is what if you have the disc. on o and the notch on 6 with multitone ( 3 or 4) will it do the same. I tried this and it does work, but will it get the same depth?? Thanks John S

I have tried this in the real world.... and could not seem to acquire a definitive answer. I still need to do more testing..... especially in a 'controlled' environment. My conditions were less than desirable.
