Kat, First Texas "comapny name" Bought out Bounty Hunter, Fisher, Tenektics "sp" ect. The 3300 up the post was made by bounty hunter, the f4 fisher looks the same but diffrent in a few ways.
Kat, the F4 has a 3 section rod, DD coil and better circut board, yes it is a bit better. If i didnt own the 3300 myself i would jump on the F4. My main machine is a Fisher F-75
bergie uses an inexpensive Bounty Hunter and his finds are pretty incredible! i dont care for them personally, but they do work, and quite well i might add, in the right hands. i think location and really knowing whatever it is you use is more important in most cases.
