I always wondered if I could get decently good with the F2 what could I do with an upgraded unit with more features, settings and abilities.
I also wondered if all the language I learned using the F2 would transfer over.
I was aiming for anything from the F5 on up but a fire sale deal on a new F70 came my way and I bit.
I didn't know what I was doing for awhile, there was so much more power to be utilized, a bit more jumpy behavior but eventually I came to realize the language was pretty much the same, nothing I learned on the F2 was wasted but there was just much more to learn.
I found really tiny and decently deep silver on my first hunt, a quality large gold ring on my third and as I learned the finds got better and better...and deeper.
The upline units just live at a deeper level than entry units, in both great soil and bad I have reached areas I could hardly believe.
I have accomplished things I never thought possible and my jaw has not stopped dropping since day one...still is.
I started a review thread that became that long F2 blog where countdown what I learned as I learned it with the F2.
I started one on the day I got the F70 and you can read all about my initial learning curve in it if you want and get an idea of what it can do.

After a cross country move from a state with some of the best soil in the country to one with some of the worst I have found that this thing is more than up to the task and I am doing things I again never thought possible in this devil dirt...things that I just could never do with the F2 before.
There is no boredom threshold in sight so far, that is important to me.
With every tweak of my settings I can see results and improvements, I have no idea when or if this will ever end.
Picking up this thing and deciding to stay in the Fisher family and use and improve on what I already knew was the best decision I have made in this hobby so far.
Planning on lots of water hunting I would go with the Pro or something else suited to that...not so much and you have a decision to make.
