Sonar X-Press™ Menu
is in Manual mode. Adjust the Upper and Lower Range together to view a
specific depth range, especially when looking for fish or bottom structure.
NOTE: A minimum distanceof 10 feetwillbe maintained between theUpper and
Lower Range regardless of the manual settings entered.
The available Lower Range settings are determined by your Humminbird® model
as follows:
587ci HD/597ci HD: Auto to 1200 ft, Auto to 400 m (International
Models only); Default = Auto
587ci HD DI/597ci HD DI: Auto to 1200 ft, Auto to 400 m (International
Models only); Default = Auto
597ci HD XD: Auto to 3200 ft, Auto to 975 m (International Models
only); Default = Auto
Chart Speed
Settings: 1 to 9, Ultra, where 1 = Slow, 9 = Fast, Ultra =
Fastest; Default = 5
Chart Speed determines the speed at which the sonar information moves across
the display, and consequently, the amount of detail shown.
A faster speed shows more information and is preferred by most anglers;
however, the sonar information moves across the display quickly. A slower speed
keeps the information on the display longer, but the bottom and fish details
become compressed and may be difficult to interpret. Regardless of the Chart
Speed setting, the RTS Window™ will update at the maximum rate possible for
the depth conditions.
For example, if you are fishing in 60 feet of water but are only interested in the
first 30 feet (surface to a depth of 30 feet), you should set the Lower Depth
Range limitto 30. Thedisplaywill show the 0to 30footrange, whichallows you
to see a more detailed view than you would see if the display went all the way
to the bottom.
