Re: Loza M gpr

I say that my company doesn't have the resources or time to obtain certification from the FCC for a piece of GPR equipment. If VNIISMI can obtain FCC certification such that it would be legal for me to purchase and use in the USA, then I'd very much be interested in Loza-N. I will convey your words...
