Chesapeake was pleased to attend OI2024 again. The show was very busy and productive and there was a lot of energy and excitement. Most visitors to our booth were eager to see SonarWiz 8.0 and learn how Automatic Target Recognition (ATR) is coming along.

We planned to include robust ATR in 8.0, but decided to spend more time on the Target Detection and Training modules, Contact Capture and Reporting, to meet or exceed user expectations. We expect to include most or all in SonarWiz 8.1 by late Q2.

SonarWiz 7.12.3 released
  • 8.0.0 coming in April; Webinar in late February to showcase it
  • 7.12.2 is a maintenance rel and the last of the 7x releases, includes:  
  • 10x faster opening of sidescan data in Waterfall
  • Added Min & Max Beam angle fields to Output Device datagram config
  • Mag Depth/ Altitude now converts feet to meters properly in 7.11
  • Grid cross-section dialog no longer reverts to enabling all possible grids
  • Grid cross-section tool works when drawing North-South profile lines
  • Waterfall speed correction has correct along-track resolution
  • SBP Edge Detection Bottom Tracking does not ignore blanking value

Chesapeake held training on board and in class Dec 11-14 at the College of Charleston again. Attendees learned the latest features of SonarWiz 7x, along with the best practices for data collection and processing, and a preview of our next major release, SonarWiz 8.0. We were pleased to be again welcoming our hardware partners to demonstrate their latest products throughout the event, with tabletop displays and boat demos.
SonarWiz at FEMME 2023
Harold Orlinsky, GM, travelled 25,000 air miles this Fall to the UK, Japan and China. He taught SonarWiz to a class of 25 during FEMME 2023, Sept 25-29, sponsored by Kongsberg Maritime.
Harold assisted with SonarWiz training for 35 trainees at Viziotex, our long time reseller partner in Japan. They presented at Techno-Ocean and the booth was very active throughout the show.

Harold assisted with a SonarWiz training in Shanghai Oct 9-11. There were more than 80+ attendees and the training was held near the offices of Geo Marine Technology, one of Chesapeake's key reseller partners there.
