Do not mount the transducer directly in the path of the at high speed. prop. The transducer can cause cavitation that may degrade the boat’s performance and damage the prop. Apply marine sealant to all screw threads to prevent water from seeping into the transom. Fishfinder 160C Owner’s Manual...
Adjust the transducer to be aligned parallel with the water. 4. Tighten the 10-32 locking nut until it touches the mounting bracket, and then tighten 1/4 turn more (do not overtighten). Fishfinder 160C Owner’s Manual NSTALLATION NSTRUCTIONS Drill pilot holes here.
6. Route the 30' (9 m) transducer cable using the supplied cable ties to secure the cable to the motor shaft.

IRING ARNESS Wiring Harness Installation The Fishfinder 160C comes with a wiring harness that connects the unit to power and the transducer with one easy-to-remove connection. If it is necessary to extend the power wires, use 22 AWG wire. DO NOT cut the transducer cable, as this will void your warranty.
After submersion, be certain to wipe and air dry the unit before reuse. WARNING: The Fishfinder 160C lens is coated with a special anti-reflective coating which is very sensitive to skin oils, waxes, and abrasive cleaners.

The unit displays fish as arches or fish symbols in three sizes and can alert you when a fish is detected. Thermocline and Structure Garmin’s See-Thru technology can display more than just the thermocline and structure, the unit displays fish in and below the thermocline, trees, brush, and deadfall.

(km). System Simulator The Fishfinder 160C comes with a built-in Simulator mode that allows you to practice and learn the operation of the unit at home rather than on the water. The unit indicates that it is running the Simulator mode by showing in the lower-left of the screen.
NMEA Output Choose to turn the NMEA Output On or Off (default). The Fishfinder 160C can output NMEA data for Water Depth, Water Temperature, and Water Speed. The NMEA output is NMEA 0183 version 3.01. Beeper Choose to turn the Beeper On or Off. When the Beeper is On, a beep is sounded when a key is pressed, a message is shown or an alarm activated.
Understanding Sonar This section is intended to help the novice user gain some understanding of how the Fishfinder 160C operates and how it can help improve fishing productivity. To understand what the unit is displaying, it is important to have a general knowledge of how the unit works and how it determines what to display.
The bottom area covered by the transmitted sound waves is determined by the beam width of the transducer, and the water depth. The Fishfinder 160C can transmit either a Narrow or Wide beam. The Narrow beam provides crisp bottom and structure detail, but the coverage area is limited.
Whiteline The Fishfinder 160C can help you to determine if the bottom is hard or soft. When the sonar soundwaves are reflected back by the bottom, a hard bottom returns a stronger signal than a soft bottom. A thin whiteline indicates a softer bottom while a thick whiteline indicates a harder bottom.
Garmin dealer for repairs. The Fishfinder 160C is fastened shut with screws. Any attempt to open the case to change or modify the unit in any way will void your warranty and may result in permanent damage to the equipment.
