What’s on the Sonar Display
Sonar Returns and Bottom View
As the boat moves, the unit charts the
changes in depth on the display to create a
profile of the
Bottom Contour
. The Sonar
View displays the sonar return intensity using
gray scale.
Strong returns
often result from rocky or hard
bottoms (compacted sediment, rocks, fallen
trees), while
weaker returns
often result from
soft bottoms (sand, mud), vegetation, and
small fish.
The shades used to represent high, medium,
to low intensity returns are determined by the
setting you choose in the
Bottom View
menu
option. See
Sonar X-Press™ Menu
to set the
Bottom View.
