Old friends get together at the MATE International ROV competition.  Chuck Richards on the left and Charlie Richards on the right meet with Marty Klein the developer of the first commercial side scan sonar. C. A. Richards & Assoc., Inc. represented Klein Associates for over eighteen years proudly selling the finest side-scan sonar made. Our friendship with Marty continues to be very rewarding. Marty and his son Jamie were judges at the recent MATE International ROV competition held in Houston.
