Quick Start Guide to Contact/Target Picking

This guide will show you how to capture contacts in SonarWiz

This Quick Start Guide will step you through creating contacts in your sidescan projects. Contacts are special markers that are associated with a particular sonar file. They consist of 2 parts:

1. A database entry that records the exact sonar file and sample on which the contact was picked as well as measurement and classification information that the user adds to the contact.

2. An image of the contact clipped from the sonar waterfall.

SonarWiz is designed to handle thousands of contacts in a project and provides a deep set of tools for working with and exporting contact information.
