Learn More About Us

“It is an excellent product to process Side Scan Sonar and SBP data. I am in the business since 1982 and from the very first time I used the program I decided to buy it (we rented it the first time) without any hesitation.

SonarWiz is an excellent product and the support is even better. Your support is more than perfect. Congratulations.”
