The Fisher F75 is the first Fisher detector released since the First Texas Company bought Fisher. First Texas manufactures metal detectors under the Bounty Hunter and Teknetics brand too. 

David Johnson was the Chief Designer of the F75. Before he was hired by First Texas, he helped design some successful detector like the Tesoro Lobo ST, Whites MXT, Troy X5, Fisher Gold Bug and others. He works now only for First Texas.  In his team on the F75 were: John Gardiner, Jorge Corral, Dimitar Gargov, Mark Krieger, Brad Fulghum, John Griffin and Tom Walsh.

What makes the F75 stand out from other top of the line detectors is that it has all of the below features that i wanted in a metal detector.

Leightweight and balance, deep, fast recovery speed, low power consumption, display, tone ID, and it is easy to use. It uses just 4 AA batteries that last over 40 hours.
