Question: I have to turn my sensitivity to 97+ just to see bottom; when I tried it once through the ice in 7 ft of water.
After it warmed up, vertical lines as if it were resetting occurs. This is not normal? Only had it for a year, but only used it once
in the summer and thought I could use it in the winter. Transducer is level and below the ice. Battery fully charged. Any ideas? Wish
I could get this working. Tim
Answer: The problem you are having sounds like the ASP isn't working properly.
This is what ASP is all about.
ASP™ (Advanced Signal Processing)
Advanced Signal Processing (ASP™) is another innovation that uses sophisticated programming and advanced digital electronics to continually
monitor the effects of boat speed, water conditions and other interference sources - and automatically adjusts the sonar settings to
provide the clearest picture possible.
ASP™ sets the sensitivity as high as possible while keeping the screen free of "noise". It automatically balances
sensitivity and noise rejection. The feature can be turned off and on and will work whether the sonar is in automatic or manual mode.
With ASP™ operating behind the scenes you'll spend less time making routine sonar adjustments and more time spotting fish.
Sensitivity
The sensitivity controls the ability of the unit to pick up echoes. A low sensitivity level excludes much of the bottom information,
fish signals, and other target information. High sensitivity levels enable you to see this detail, but it can also clutter the screen
with many undesirable signals.
Typically, the best sensitivity level shows a good solid bottom signal with GRAYLINE® and
some surface clutter. When in the automatic mode, the sensitivity is automatically adjusted to keep a solid bottom signal displayed,
plus a little more. This gives the unit the capability to show fish and other detail. In automatic mode, the unit also adjusts sensitivity
automatically for water conditions, depth, etc.
When you adjust the sensitivity up or down, you are biasing up or down
the normal setting the unit's automatic control would choose. With ASP™ enabled, the automatic mode picks the proper sensitivity level
for 95% of all situations, so it is recommend to always use this normal mode first.
But, for those unusual situations where
it is warranted you can bias it up or down. You can also turn off the automatic sensitivity control for special uses. To properly adjust
the sensitivity while the unit is in the manual mode, first change the range to double its current setting. For example, if the range
is 0 - 40 feet, change it to 0 - 80 or 0 - 100 feet.
Now increase the sensitivity until a second bottom echo appears at
twice the depth of the actual bottom signal. This "second echo" is caused by the echo returning from the bottom reflecting off the
surface of the water, making a second trip to the bottom and returning. Since it takes twice as long for this echo to make two trips
to the bottom and back, it shows at twice the depth of the actual bottom.
Now change the range back to the original scale.
You should see more echoes on the screen. If there is too much noise on the screen, back the sensitivity level down a step or two.
Now, there are a couple of reasons why this could be happening.
You could be getting interference from other fish finders that may be close to you.
You may have a bad transducer.
If you have any angler friends using a Eagle Cuda 242 fish finder see if you can swap the
transducer and test on both units. This will verify if it is in the transducer or in the fish finder. You can try taking the transducer
back to where you bought it and see if they will allow you to test it on a display model.
Check to see if there are any
nicks or cuts in the transducer cable and check for corrosion at the connection to the fish finder.
Try turning the ASP off and see if it makes a difference.
If everything fails you will probably have to send the unit back for service.
