FOREWORD
A Word to the Owner of the DFF3
Congratulations on your choice of the FURUNO DFF3 Network Sounder. We are confident you
will see why the FURUNO name has become synonymous with quality and reliability.
Since 1948, FURUNO Electric Company has enjoyed an enviable reputation for quality marine
electronics equipment. This dedication to excellence is furthered by our extensive global network
of agents and dealers.
This equipment is designed and constructed to meet the rigorous demands of the marine environ-
ment. However, no machine can perform its intended function unless operated and maintained
properly. Please carefully read and follow the recommended procedures for operation and main-
tenance.
Thank you for considering and purchasing FURUNO.
Features
The DFF3 network sounder is a dual frequency echo sounder designed for use with the FURUNO
NavNet, NavNet vx2, NavNet 3D and Navnet TZtouch series. The DFF3 feeds data about under-
water conditions via a LAN.
• FURUNO Free Synthesizer (FFS) transceiver design allows use of user-selectable operating
frequencies (28 - 200 kHz).
• Automatic operation selects correct range and gain to show fish echoes and bottom in both
shallow and deep waters.
• Improved discrimination of near-surface fish by eliminating the transmission line.
• Heaving compensation* stabilizes the picture against ship’s pitching and rolling. * Requires
NavNet 3D/TZtouch display device plus Satellite Compass SC-30.
• Approximate fish length calculation available with conenction of transducer 50/200-1T. (NavNet
3D and TZtouch only.)
• 1/2/3 kW output
Note: The terms “NavNet”, NavNet vx2”, “Navnet 3D” and “NavNet TZtouch” refer to the models
