Chesapeake SonarWiz V8.3.0 (Sonar Survey Software Guide 2026)

Overview of Chesapeake SonarWiz V8.3.0

Chesapeake SonarWiz Technology has been a leader in sonar data processing for more than 25 years, serving hundreds of clients worldwide, including NOAA, NAVO, USGS, and numerous navies and universities. SonarWiz was developed to address the need for an easy-to-use, low-cost, high-value sonar data acquisition system that simplifies the survey process.

The software is modular in design, allowing users to purchase each component separately as an add-on or as part of a Field or Office bundle. The platform supports dongle and dongle-free licensing options, providing flexibility for different operational environments.

SonarWiz V8.3.0 continues this legacy by offering an all-in-one solution that captures sonar, navigation, fathometer, payout meter, and magnetometer data simultaneously, enabling operators to customize real-time displays that include sidescan and sub-bottom waterfalls, contact target strips, and fully processed mosaics.

What’s New in SonarWiz V8.3.0

The V8.3.0 release represents a significant update with over 60 changes and improvements. Here are the key additions:

Dark Mode Interface

SonarWiz 8.3.0 finally introduces Dark Mode, a feature that has been highly requested by users. This is particularly beneficial for professionals working in dimly lit environments, such as survey vessel cabins or computer labs during nighttime operations.

New Real-Time Magnetometer Interface

The new magnetometer interface supports multi-channel systems that collect data at rates exceeding traditional 1 Hz limitations. During development, Chesapeake Technology specifically created an interface for the Geometrics MagElement magnetometer, expanding the platform’s compatibility with modern magnetometry equipment.

Enhanced Gridding with Polygon Restriction

A new tool allows users to restrict grid program operations to polygons drawn with the feature tool. This is particularly useful when working with irregularly spaced track lines, as it prevents the grid program from making unrealistic assumptions about depth continuity across large distances.
