the first tone is a single tone.....and the second (the default setting) is a dual tone similar to 2F on the f75. There are also 3 and 4 tone selections too.
As far a the low conductor sensitivity goes.............its definately better than any of the classic series detectors. Dont get me wrong........I've always LIKED the classics.and considered them 'sleepers". A very good bang for the buck...especially with Bills mods. we have 5 of them..................in various configurations.
The modulated audio is going to be a GOOD tool for gleaning more info about the target under the coil. A few hours "ear' time...and the user will get the hang of it real quick.
I use the two tone pretty much exclusivly, as it sounds most like my F75 in that mode.......................BUT............it gives you more audio clues than the 75 does. Ought to be interesting once a few guys get a few hours under their belts. The combination digital and analog controls put everything at your finger tips, and that makes it easy to use and intuitive. should be a REAL easy machine to learn and use...............
If you like or are forced to hunt in AM from time to time..your gonna really like the autotune mode too. I remember when I first got the 5....and took it in the back yard for a spin.......I just threw it together and tried it out....and didnt even peek at the manual yet. I put it in AM... ground balanced it.......and hunted for nearly 5 minutes before I noticed it was STILL in AM.
DEE DEE DEE
It sounded soooo good I didnt even realize it was still in AM!!
Nice and smooth....... Streak!
