Superfluid--insulator transition in an ultracold Fermi gas in the external disorder potential of the amplitude

V

₀ is studied as a function of its concentration

n

and the magnetic field

B

in the presence of the Feshbach resonance. We find the zero temperature phase diagrams in the plane (

B,n

) at a given

V

₀ and in the plane (

V

₀,n) at a given

B

. We study the transition between cases of classical and quantum random potentials which can be implemented by tuning intensity of speckles. Our results for Bose

Einstein condensation side of the diagram are also valid for a Bose gas.
