TRANSDUCER
Simrad 200-7C
200 kHz Single-beam transducer
(855-164231 Rev
.B)
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.
