All sonar equipment has 2 blind spots. A blind spot is
0.5 meters down from the surface of the water. Anoth-
er blind spot is 0.3 meters from the bottom of the water.
If the fish is in the blind spot, the fish finder is difficult
to detect. Therefore, if the water is too shallow, most of
the fish are in the blind spot. Therefore, in order to ob-
tain a better fish detection effect, we recommend that
you use this product in waters not less than 1.5 meters.
1) The oil, dirt, etc. floating on the water surface will
form a film on the bottom of the probe, thereby red-
ucing its detection effectiveness. Please clean the sur-
face of the probe with a clean soft cloth (preferably
dipped in some alcohol).
2) Its detection capability can theoretically reach 60
meters. However, it depends on the conditions of the
water bottom. For example, a lot of silt at the bottom
will cause weak echo signals and reduce its detection
ability.
1)When the boat travels far (200 meters away), or at
night, foggy weather, etc., you will not be able to see
the direction of the bow. With the compass function,
you can clearly know the direction of the bow on the
screen, so you can navigate it back accurately.
2)If the speed of the boat is less than 0.6 m/s, the he-
ading direction provided by the GPS data will be wr-
ong. When the ship approaches the target point with
very slowly speed, only GPS with compass function
can accurately control the ship to reach the target lo-
cation.
With the help of a compass, you can even accurately
observe the heading direction of the boat when the
boat is moving slowly.
No fish detected
(Clear that there
are fish in the water)
There is no depth
reading on the
screen when the
water depth
exceeds 60 meters
Why need the
compass function?
Isn’t that enough
with GPS navigation
function ?
