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
