Gain Control
Turn the Gain Control clockwise to increase the gain. Keep the gain
as low as possible. The Gain Control also serves as the ON/OFF
switch for the Interference Rejection feature by pushing in on the
control. The red light indicates if the IR feature is on or o.
Depth Scales
Shallow Range Group
• S-1: Zero to 20 feet. Read the outer white scale directly.
• S-2: Zero to 40 feet. Read the outer white scale and double the reading.
• S-4 : Zero to 80 feet. Read the outer white scale and multiply by 4.
Deep Range Group
• D-1 = Zero to 30 feet. Read the inner yellow scale directly.
• D-2 = Zero to 60 feet. Read the inner yellow scale and double it.
• D-4 = Zero to 120 feet. Read the inner yellow scale and multiply by 4.
Interference Rejection
Interference Rejection comes on automatically when you power
up the asher. If interference from another sounder is present on
the display, push the Rejection button repeatedly until it goes
away or is reduced as much as possible. There are 10 settings
to cycle through.

se comes standard with a 19° Ice-Ducer transducer. This is the
widest beam angle available. You may also purchase additional transducers
with narrower beam angles and/or for boat-mounted applications (see
