Scroll speed
Use this to set the scroll speed on the display.
There is a choice of: Very Fas t, Fast,
Medium, Slow and Pause. The depth of the
water also affects the speed of th e display.

shows the most fish detail. Medium or Slow
scroll speeds result in sonar infor mation being
displayed over a longer period, but wit h less
detail. See Section 4-1 Interpretin g the display,
for more information.
Fish symbols
These appear only in the main sonar di splays.
Fish symbols can be shown in three ways:

• As a fish symbol with the depth
(Symbol+depth). T he depth is shown
beside the fish symbol.
• As a depth (Depth). The depth is shown
above where the fish was detected
• Switched off (Off) so that echoes are not
converted to fish symbols but are disp layed
directly.
See section 4-3 Fish detection an d display, for
