This viewis used for finding fish.À Color legendÁ BoatÂ RangeÃ BottomÄ StructureÅ FishFrontVü Sonar ViewThe Panoptix FrontVü sonar view increases your situationalawareness by showing obstructions under the water, up to91 meters (300 feet) in front of the boat.The ability to effectively avoid forward collisions with FrontVüsonar decreases as your speed rises above 8 knots.To see the FrontVü sonar view, you must install and connect acompatible transducer, such as a PS21 transducer. You mayneed to update the transducer software.Selecting the Transducer TypeBefore you can select the transducer type, you must know whatkind of transducer you have.This chartplotter is compatible with a range of accessorytransducers, including the Garmin ClearVü™ transducers, whichare available at www.garmin.com/transducers.If you are connecting a transducer that was not included with thechartplotter, you may need to set the transducer type to makethe sonar function properly. If the device automatically detectsyour transducer, this option does not appear.1 From a sonar view, select Menu > Sonar Setup >Installation > Transducer Type.2 Select an option:• If you have a 200/77 kHz, dual-beam transducer, selectDual Beam (200/77 kHz).• If you have a 200/50 kHz, dual-frequency transducer,select Dual Frequency (200/50 kHz).• If you have another type of transducer, select it from thelist.Calibrating the CompassBefore you can calibrate the compass, the transducer must beinstalled on the shaft far enough away from the trolling motor toavoid magnetic interference, and deployed in the water.Calibration must be of sufficient quality to enable the internalcompass.NOTE: To use the compass, you must mount the transducer onthe shaft. The compass does not work when you mount thetransducer on the motor.NOTE: Compass calibration is available only for transducerswith an internal compass, such as the PS21-TR transducer.You can begin turning your boat before calibrating, but you mustfully rotate your boat 1.5 times during calibration.1 From an applicable sonar view, select Menu > Sonar Setup> Installation.2 If necessary, select Use AHRS to turn on the AHRS sensor.3 Select Calibrate Compass.4 Follow the on-screen instructions.Creating a Waypoint on the Sonar Screen1 From a sonar view, drag the screen or select .2 Select a location.3 Select New Wpt or .4 If necessary, edit the waypoint information.Pausing the Sonar DisplayFrom a sonar view, select .Viewing Sonar HistoryYou can scroll the sonar display to view historical sonar data.NOTE: Not all transducers save historical sonar data.1 From a sonar view, drag the screen to the right.2 Select Back to exit history.Sonar SharingThis feature may not be available on all chartplotter models.You can view the sonar data from all compatible sources on theGarmin Marine Network. You can view sonar data from acompatible external sonar module, such as a GCV™ sonarmodule. In addition, you can view the sonar data from otherchartplotters that have a built-in sonar module.Each chartplotter on the network can display sonar data fromevery compatible sonar module and transducer on the network,Sonar Fishfinder 23
