No way to know yet.
I would probably compare it to the Ace 150, the 250 and F2 seem a bit more advanced to me but very little info to go on so far.
Could have a little of the new tech FT is putting into other models that could make it a bit special, new shielding or other stuff, but until we see how it actually works in the field, who knows.
I guess shipping on all 3 new models start this week so hopefully more in the field vids and reviews will show up soon.
All I can say is anything Fisher makes will have a faster reset time than any Ace machine. Also your getting a newer technology. Plus a pinpoint mode over the Ace150. Over 1 pound lighter. Here is a chart. But I believe I heard the F11 ran on one 9 volt battery. The other two are two AA's. I would at leat buy the 22 for the added features and it being weatherproof..... http://md-hunter.com/fisher-f11-f22-and-f44-what-is-the-difference-table/
