TRANSDUCER

Simrad 200-7C

200 kHz Single-beam transducer

Introduction

The 200-7C is a composite, single-beam transducer with a large bandwidth. It provides considerable range resolution and allows targets to be detected at a depth of 10 cm below the transducer due to its rapidly decaying transmission pulse.
