Simrad 38/200 Combi W
Dual frequency echo sounder transducer
Beam pattern, 200 kHz
TECHNOLOGY FOR SUSTAINABLE FISHERIES

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 sh 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
scientic use.

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