Simrad ES200-7 DATASHEET

Product specification

Simrad ES 200-7

Transducer

Introduction

The ES 200-7 is a split-beam, composite trans­ducer with a large bandwidth. This provides a fine
range resolution, which is important for single fish
detection and target strength measurement. The
transducer has four quadrants. The specifications
below are valid when all four quadrants are con­nected in parallel.
