Single Beam Sonar
The PiranhaMAX™150 and PiranhaMAX™190c use a 200 kHz single beam
sonar system with a 20° area of coverage. Boat speed, wave action, bottom
hardness, water conditions and transducer installation can all affect depth
capability.
Dual Beam Sonar
The PiranhaMAX™160 and PiranhaMAX™170 use a 200/83 kHz dual beam
sonar system with a wide (60°) area of coverage. Dual Beam sonar is optimized
to show the greatest bottom definition using a narrow (20°) beam yet can still
