The new Fisher F4 being brought out by Bounty Hunter is based on the 3300 but way more powerful. But the amazing thing is the coils are interchangable, the F4 comes with an 11" DD coil like the T2, this means a 11" widescan coil can be used on the 3300 making it more stable in mineralized areas and much deeper and maybe a faster recovery rate. Things are getting interesting ?
