FLASHER OPERATION

Basic Use

The Vexilar FL series color ashers are great tools for open water and ice shing. Once you

learn to understand the color display, you can apply this knowledge to greatly increase

your awareness of what’s under the water.

FL Se r i e S FL a S h e r S Ca n Be US e d Fo r :

• Determining the current depth at any boat speed.

• Locating sh-holding underwater structure.

• Determining the bottom hardness and transition lines.

• Penetrating thick vegetation to see what’s below.

• Finding sh and the bait they feed on.

• Watching your bait and the sh around it.

Operation of each of the asher models is very straight forward. You simply turn the unit

on, select an appropriate depth range setting, and then an appropriate gain level setting.

You should change the range and gain settings only when the conditions change.

RANGE

Range determines the maximum depth of water in which the asher can see the bottom.

For example, the shallowest range available on the FL-22HD is 0 to 10 feet. This means

that if the water depth is between zero and 10 feet, the bottom will be displayed on the

screen. If the water depth gets deeper than 10 feet, you’ll want to select a deeper depth

range in order to see the bottom.

DID YOU KNOW ?: It is usually best to select the shallowest depth range possible to see

the bottom. This allows the water column below to be represented by the greatest amount

of display screen area. This offers the highest resolution, makes things bigger and easier

to see.

GAIN

Gain controls the amount of ampliﬁcation applied to the return sonar signal. Think of gain

as your volume control. You turn up the gain to see more of what’s below. You turn down

the gain to see less of what you don’t want to see. The goal is to nd a gain level that

shows you as much real information as possible, without displaying stray signals of clutter

and interference. Keep the gain setting as low as possible for best overall performance.

INTERFERENCE REJECTION

This feature rejects sonar interference generated by other nearby depth sounders.

Interference Rejection, or IR, comes on automatically when you turn the asher on, but

you can adjust the setting if desired. Learn more on page 11.
