Provides the basic information you need to operate the Simrad SP90 Low frequency, long range fish finding sonar.
The Simrad SP90 is a large and expensive instrument designed for fish finding. This document serves as a short introduction to its operational use, focusing on the display and control panel rather than detailed functionality.
Key operational procedures covered include powering the unit on and off safely, navigating the horizontal and vertical menus, adjusting gain settings (AGC, TVG, ROG), managing sonar images (storage, recall, deletion), and utilizing automatic search and tracking features.
The purpose of this booklet is to give you a short introduction to the operational use of the SP90 sonar.
For more detailed information, refer to the Operator manual provided with the sonar.
You must ensure that you have sufficient water depth because the transducer is lowered down below the vessel's hull when powered up.
