Selecting the Power Setting
The POWER MODE Functionbar button allows adjustment of the
transducer signal. When AUTO is selected (default), the Fishfinder
automatically determines the power setting based on the current depth.
LO power (10 W) is used in depth ranges less than 20 feet and HI
power (600 or 1000 W, depending on your transducer) is selected for
depths greater than 20 feet. When AUTO is selected the current
automatic power setting is indicated in the top status line by an L
(low) or H (high). If you want to manually adjust the power to suit
current conditions, you can select either LO or HI power. The power
setting is retained when the unit is powered off.
To change the power setting:
1. On the Pathfinder Panel, click MULTI to display the
associated Functionbar buttons.
2. Click Power Mode . A drop-down menu appears.
3. Click to choose between AUTO , LOW , or HIGH power.
The selected setting is highlighted.
4. Click ENTER , CLEAR , or BACK to return to the top-level
Functionbar menu.
Selecting the Frequency
The hsb
2
Series Fishfinders use dual frequency sonar. The two
frequencies used are 50 kHz and 200 kHz. The Fishfinder
automatically selects the appropriate frequency. Alternatively, you
can manually select either frequency, or both frequencies
simultaneously. Each is suitable for a particular purpose:
50 kHz Frequency – When using this frequency, the transducer scans a
wide area. The 50 kHz signal penetrates water well, and is good for
use in deep water.
200 kHz Frequency – When using this frequency, the transducer scans
a narrower area, but produces a more detailed view. The 200 kHz
signal is good for finding fish near the bottom or close together, and is
better suited for use in shallow water.
