I used an F2 that came with 2 coils for 3 seasons, found a ton with the 8"coil but found way more with the sniper.
I bought this just as a backup/take on vacation detector but it worked so well, was so much fun to use and found me do much right out of the box it became my prime tool for the next 3 years.
At least 3 members of my club bought this same unit because they saw me winning contest after contest with it at our monthly meetings including most coins dug several years in a row.
The small sniper coil is better to learn this machine with as a newbie and I tended to hunt mostly trashy sites so that coil stayed mounted most of the time after I put it on as a lark.
My $200 investment turned into over $2000 in clad, silver and gold finds for me,the fun I had with it was priceless.
Discontinued now, the new Fisher F22 took its place but it is still being sold and there is still great value in that 2 coil package while it lasts.
The silver is great but still no screen, I love Tesoros and own 2 myself but hunting with screen units are also fun but in a different way than that Compadre which he might like.
The Ace 250 has no screen.
The Whites is ok but again no VDI numbers...if you get a screen unit you will not believe how handy this feature is.
The 4000 is decent but slower than the F2...the fast recovery the Fishers posess is one of their prime assets.
Like most Fishers it is light as a feather.
No manual GB but I used mine in some of the worst soil in the country and some of the best...found tons in both kinds of soil.
In the really bad stuff manual GB wasn't a whole lot if help, in the good stuff it wasn't really needed.
Useable on the saltwater beach, kinda, but no single frequency units will work well in saltwater or wet sand...dry sand no problem.
Home sites...the sniper coil will come in very handy there.
Parks...that is my prime hunting spot and can't tell you how well this thing works there.
Wait...actually I can, Google, F2...final impressions.
One of the longest threads on the net and what started out as a simple review turned into a daily log of what I learned as I learned it and what I found along with many other happy owners.
This thread is responsible for selling a ton of F2's over the years.
