MRTOOKIE32,
Where your USN60 will come up short is meeting paragraph d of the code case which mandates a data acquisition system. Unless you are capable of outputting the a-scans from the USN60 into a PC for storage and manipulation. That paragraph eliminates all hand manipulated instruments including hand manipulated phased array units. As I read the code case they are mandating a system which will store all of the a-scan data to allow post test replay and analysis. Of course positional data would also be necessary.
I have never used the code case, so there could be other interpretation out there.
