Simrad 38-200 COMBI W - DATASHEET REV B Datasheet

Simrad 38/200 Combi W
Dual frequency echo sounder transducer
Introduction
The Simrad 38/200 Combi W is a
dual frequency transducer (38 and 200
kHz), and both frequencies operate
with wide beams (31°). This makes
the transducer perfect for shallow
water fish detection using the 200 kHz
frequency, and excellent for bottom
discrimination from shallow depths
and down to several hundred meters
using both frequencies.
The transducer is not suited for
scientific use.

Note: The transducer must be
submerged in water when transmitter
power is applied. Transmitting in
air will damage the transducer
permanently.
