SCROLLING GRAPH (CHART) DISPLAYS

— These windows will show not 

only what is happening below you in real time, but will also enable the user to 

have a “history” of what has happened. While most commonly used for open 

water, many anglers are discovering the benefits of using a graph on the ice. 

The Marcum Digital Sonar stands apart from other graphs in that it displays 

with ultra-fast “True-Time” sonar response – less than .02 seconds between 

the echo reaching the transducer and when the signal appears on the LCD 

screen. Other graphs experience a much longer response time. When used 

from a boat in open water, the user will see signals displayed in classic “graph” 

fashion; the bottom will be a solid band, and fish or other objects display as 

“arches”.   

When used from a stationary position, such as ice fishing, the bottom will 

display as a solid band, but other signals, like fish or your jig, will display as 

lines of varying thickness.  Always remember that the thicker the band, the 

stronger the signal.  A large fish is likely to display as a fairly thick band, while 

a small ice jig will show as a very fine line. The best way to learn how to 

interpret signals on the graph is to have it displayed along with the circular or 

vertical display. After using the graph along with one of the more familiar 

displays, you may find that you like fishing with the graph best of all. It is 

fascinating to watch the “trail” of your jigging motion, and fine tuning your 

presentation to exactly what the fish want has never been easier. 

The Marcum Digital Sonar has the option of displaying a full water column 

graph, as well as an adjustable zoom graph. The interpretation of these signals 

improves with experience and use in the field. 

BATTERY CHARGER TROUBLESHOOTING 

A majority of inquiries that come to our office are battery or battery charger 

related.  Battery failure can be caused by a fault in the charging system, and 

many times the issue is with the fuse on the wiring harness. If you suspect your 

battery is not being charged, follow these troubleshooting tips: 

1.

When the charger is plugged into the 

WALL ONLY

 it should show a green 

light.  If there is no light showing, confirm that the outlet is good. If the outlet is 

good, it is very likely that the charger itself is faulty. 

2.

If the charger is plugged into the 

BATTERY ONLY

 it should show a green 

light.  If it does not show a green light, it is likely that the charger is not making

contact with the battery.  The most likely reason for this is a faulty fuse on the 

wiring harness.  This fuse is a 2-amp automotive fuse, and it should be 

replaced with a 2 or 3-amp fuse available anywhere that sells auto parts.  The

fuse can blow out if there is a short in the charging system, or if the plug end 

of the wiring harness comes in contact with a battery terminal. 

3.

When the charger is plugged into both the wall 

and 

the battery, there should 

be a red light showing on the charger.  A red light showing indicates that the 

charger is in contact with the battery and is actively charging the battery.

Once the battery has reached a voltage level that is considered “fully charged” 

the red light should change to green. If after 24 hours the light has not 

changed to green there is no cause for alarm!  Remember that when the light 

is red, the battery is being charged, and you will be able to use your system. 

4.

If it has been over 24 hours and the light is not green, the first thing you 

should do is unplug the charger and turn on your Digital Sonar. The Digital
