RezBoost
™
With connection of a RezBoost
™
capable transducer, echo resolution can be im-
proved. For example, previously it was difficult to distinguish fish from the seabed
echoes. With [Enhanced] RezBoost
™
, however, fish near the bottom are clearly seen.
Note:
The RezBoost
™
feature is not available with CHIRP transducers. See the
equipment list in the Installation Manual for details.
To use the RezBoost
™
feature, swipe the bottom of the screen upwards to show the
layered menu, then tap [RezBoost] => [Enhanced]. To disable the RezBoost
™
feature,
tap [Standard].

Fish Finder Alerts and Alarms
The fish finder has four main alarm settings: detection level (based on echo strength),
school (bottom), single fish size and seabed composition. When the conditions of an
alarm are met, the buzzer sounds and the applicable alarm message appears at the
top of the screen. Tap the alert message to silence the buzzer. The icon remains on
the screen until the offending alarm is disabled or the condition that caused the alarm
has ended.

How to set the detection level
Detection level determines the echo strength at which an echo is interpreted as a
school. Echoes which are estimated to be a school trigger the fish detection alarm.
1. Tap [Home] => [Settings] => [Notifications] => [Fish and Bottom].
2. At [Fish Detection Level], tap the echo strength you want to set as a threshold.
Echoes with a strength lower than this setting do not trigger the fish detection
alarm.
3. At [Fish], tap the toggle box for [Notification] to show [ON]. The menu items for
[Depth] and [Range] are now active and selectable.
4. Set the [Depth] (from transducer) to set the start point for the detection area.
Drag the slider, or tap the keyboard icon to input a value.
5. Set the [Range] (width) of the detection zone in a similar manner.
6. Close the menu.
6.19.2
How to set the alarm for fish near the seabed
You can set a detection zone based on an area near the seabed. Fish detected within
the set range from the seabed trigger the fish detection alarm.
1. Tap [Home] => [Settings] => [Notifications] => [Fish and Bottom].
2. At [Fish B/L], tap the toggle box for [Notification] to show [ON]. The menu items
for [Depth] and [Range] are now active and selectable.
