function properly if there is air between the sonar sensor and the water surface; keep this
in mind when using the device through a boat hull or ice.
I See Fish Under the Sonar Sensor, but Nothing Appears on the Display
As with the depth reading, the fish finder will not detect any objects that are closer than
2.5 ft from the sonar sensor. If you’re fishing in water that is less than 3 feet deep, it is
recommended to discontinue use of the fish finder.
The Depth Reading is Incorrect
Make sure that you are pointing the sonar sensor perpendicular to the water when trying
to obtain depth readings.
Extremely heavy vegetation may confuse the sonar of the fish finder causing it to
misinterpret the depth. If you are certain that the readings are incorrect under these
conditions, discontinue use.
I’m Not Getting A Reading While Trying to Shoot Through My Boat Hull or Ice
Shooting through the hull of a boat/canoe or ice can be difficult, as hidden air pockets will
prevent you from obtaining a reading. Make certain that the hull or ice is solid from the
surface to the water with no air bubbles and/or gaps. Shooting through composite hulls
(plastic) or cloudy ice is not possible as tiny air bubbles are usually present in these
situations.
I’m Getting False Fish Indications
The most common cause of false fish indications is extremely tall weed growth. If weeds
grow taller than 50% of the total water depth in a particular area, the sonar will mistake it
for fish. Trash & debris may also give false readings.
