Howdy, I hope you enjoy yours as much as I enjoy mine, IMO, be prepared to have a ton of fun! I am really impressed with this machine - its become one of, if not, the favorite one for me. I can on ly speak for myself and what I think, so.... one real smooth machine, very sensitive, the stuff I find, amazes me! The target ID, seems to bulldog the item for good finds... locks right on! Very stable. Depth guage is pretty much on the money as well... "I" think mine is plenty deep enough, and yes, thats even on the high conductive stuff... silver, coins etc... I love the red backlight... as I'm mostly a night hunter... I set mine to "2" for brightness and works great!
Like others have said, can set that bad boy right to max and she'll run nice and quiet! I also like setting to 100, and VCO at 40 with zero disc. This machine, IMO is pretty darn amazing. I have the F70 and really have enjoyed it etc.... especially once you start to have spent some time with the 70, you can get i tto run quiet etc... and its amazing in sensitivity etc as well... but, for me, between the two, and I know many will disagree most likely, but again, for me, I give the nudge to the F19. I will probably be posting my F70 on Craigslist... don't get me wrong, its not because I don't like it, I do... its just I don't feel I need both the F70 and the F19... and for me, again, a slight nudge to the F19 for my hunting needs. Fun machine though... I feel as some others feel, this may well be a pretty good sleeper unit.
Anyways, enjoy and have fun!!! Hope you like yours as much as I like mine. Good luck!
