MAX DEPTH
(Advanced)
Max Depth adjusts the maximum depth of operation. The performance of your 900
Series™ can be tuned to the maximum depth you will be fishing in by setting the Max
Depth. When a maximum depth is set, your 900 Series™ will not attempt to acquire
sonar data below that depth, thus increasing overall performance. When Max Depth
is set to Auto, the 900 Series™ will acquire bottom readings as needed (within the
capacity of the unit). If the bottom is deeper than the Max Depth setting, the digital
depth readout will flash, indicating that the 900 Series™ cannot locate the bottom.
The Max Depth menu choice is available when User Mode is set to Advanced (see
Setup Menu Tab: User Mode).
T
o change the Max Depth setting:
1. Make sure you are in Advanced User Mode, then highlight Max Depth on the
Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Max Depth
setting. (AUTO, 10 to 2500 feet for 937c DF Combo and 931c DF models, 10 to
1000 feet for 937c Combo and 931c models, 3 to 780 meters for 937c DF Combo
and 931c DF models, 3 to 330 meters for 937c Combo and 931c models
[International models only], Default = AUTO)
WATER TYPE
(Advanced)
Water Type configures your unit for operation in fresh or salt water. The Water Type menu
choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).
NOTE: In salt water, what would be considered a large fish might be 2 to 10 times bigger
than a large fish in fresh water (depending on the type of fish you are seeking). The salt
water setting allows for a greater range in fish size adjustment to account for this. Also,
make sure that the Water Type is set accurately, especially in salt water, as this affects the
accuracy of deep water depth readings.
To change the Water Type setting:
1. Make sure you are in Advanced User Mode, then highlight Water Type on the
Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Water Type
setting. (Fresh, Salt, Default = Fresh)
TRANSDUCER SELECT
Transducer Select allows you to select which
transducer you want to use, Single Beam or Dual 50/200 Beam.
NOTE: The transducer setting must correspond to the transducer type connected to your
system. If you have a Single frequency (937c Combo or 931c model) control head, you will
need to set Transducer Select to Single Beam in order for your control head to work
properly.
To change the selected Transducer:
1. Highlight Transducer Select on the Sonar Main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the transducer
selected. (Dual 50/200, Single Beam, Default = Dual 50/200)
