I am in love with my Fisher F75, but I wouldn't go straight from the Ace 250 to an F75. The learning curve is a little bit tough to get through, and it is so sensitive that there is a lot of noise going on the hotter you run it. I had a GTI 2500, and could find clad and silver rings at a blistering pace, and didn't think it could be outdone for newer sites. The weight got to be too much for me because of several disablilties, and I went to the Minelab x-terra 70 for the lighter weight.
I love the x70, and I would suggest that is your next choice for it's depth, pinpointing, tones, and being a very nice machine for the price. Look at the deal right now here on tnet
http://forum.treasurenet.com/index.php/topic,179992.0.html Hard to beat that price, especially with the coils. The learning curve is very short and you will love the machine.
The F75 I use now because it is so well balanced. It weighs more than the x70, but the balance makes it easier in my shoulder than any other detector I have used. I find more clad and rings than I ever did with the 2500 because of the coverage area of the DD coil. It goes deep almost the full 11 inches of the coil, and you can swing fast and get awesome target seperation at the same time. It has also been getting good reviews for wet ocean sand, but of course the control box is NOT waterproof.
The Explorer's were heavy and you had to swing slower to get the better finds. They are awesome machines, but just not my style. In my opinion the Explorer SE and the F75 are the 2 best detector's out there, but the Xterra 70 will be close behind and easier to use. The x70 can also be used at a faster swing speed then the explorer and get good target seperation.
My 2 cents. Free advice is sometimes worth the price paid, so hopefully this gives you a few ideas.
