If you are familiar with sonar, and can determine what is on the chart, this section may not be for you. This section is intended to help the novice user gain some understanding of how the Fishfinder 160 operates and how it can help improve their fishing productivity.
Transducer Coverage The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth. Using Garmin’ s standard 20° transducer, the coverage is approximately 1/3rd of the water depth. As shown in Example 1, the coverage area at a 30 foot depth is approxi- mately a 10 foot diameter circle.
On the Water On the Water Understanding the Chart Branches Enlarged Transducer View Fish Remember that the Fishﬁ nder displays a 2D picture of the underwater environment. The ﬁ sh and tree could be located anywhere in the coverage area at that slice of time.
Whiteline The Fishﬁ nder 160 can help you to determine if the bottom is hard or soft. When the sonar soundwaves are reﬂ ected back by the bottom, a hard bottom will return a stronger signal than a soft bottom. The stronger bottom return, the wider the bottom layer is displayed.
On the Water Understanding the Chart Thermoclines One of the unique features offered by GARMIN is See-Thru® technol- ogy. See-Thru® technology allows the Fishfinder 160 to see through thermoclines and helps locate fish where they live, and fish love the thermocline.
The message will be replaced by the simulator mode icon in the lower left corner of the chart. While in the simulator mode, the unit will display a random bottom scene and the Fishfinder 160 can be controlled just as if it were on the water.
Alarm Messages and Icons The Fishfinder 160 displays a message when an alarm is tripped. To clear the message press the ENTER key. If the ENTER key is not pressed, the unit will automatically remove most messages after 10 seconds and display a reminder icon in the lower left corner of the chart until the alarm is no longer valid.
The Portable Case is designed for rugged use and provides storage for the Battery Pack and the Portable Suction Cup Transducer and a mount for the Fishﬁ nder 160. The case is water resistant but is not designed to ﬂ oat in the event it should go overboard.
Batteries The Fishﬁ nder 160 Portable comes with a D-Cell battery pack. Eight D-Cell Alkaline batteries will provide approximately 20 hours of continu- ous operation. You have the option of purchasing a 12 Volt Rechargeable Gel-Cell Battery for the portable case.
