DualBeam PLUS Sonar
DualBeam PLUS sonar provides conical coverage directly below the boat. The beam can be adjusted to show the medium, high,
or medium-high frequency range. DualBeam PLUS sonar returns are displayed on the Sonar (2D) Views.

Select Medium Frequency for deep water (more than 800 feet).
Medium
Medium Frequency can be used for deep returns at high speed. If
(83 kHz) Fre-
Medium Frequency is selected, the high frequency beam pings in the
quency
background but is not displayed.
High
Select High Frequency for more detail at shallower depths (less than
(200 kHz) 800 feet). If High Frequency is selected, the medium frequency beam
is not available.
Frequency
Select Medium/High Frequency to ensure both beams ping
continuously, so the sonar history is not interrupted if the Sonar
Medium/
View is closed.
High
The returns from both beams are blended by starting with the wide
(83/200 kHz)
beam return, dimming it, and then overlaying it with the narrow
Frequency
beam return. The narrow beam sonar returns will stand out from
the wide beam sonar returns.

Select 50 kHz for deep water (more than 1500 feet). 50 kHz can be
50 kHz
used for deep returns at high speed. If 50 kHz is selected, the 200
(Low)
kHz beam pings in the background but is not displayed.
200 kHz Select 200 kHz for faster pinging and shallower water (less than 800
(High) feet).
