MODE CONTROL

The Mode control selects the FL-18s output power level and zoom view.

The Normal position will be the setting that is used most often. With the

Normal setting, the FL-18 operates in the standard flasher mode with

normal (high) power. The depth is read using the outer white scale on

the display.

LP, or Low Power, Mode is used for shallow water conditions. Generally

depths of 15 feet or less. The FL-18s LP Mode output power level is

approximately 50% less than the Normal Mode. Depth is determined in

the same way as the Normal

Mode.

AZ, or Auto Zoom, splits the

screen of the FL-18 into two dif-

ferent sections. Refer to figure L.

on page 14. Given that the range

control is set to x2, here is how to

interpret the display:

The right hand side of the dis-

play shows the full water column

below. Instead of reading the

white numbers for depth, you now use the inner yellow scale. The lead-

ing edge of the bottom lines up close to the 15 foot area of the yellow

scale. With the range set to x2 you interpret the depth as around 30 feet.

The left side of the display shows only the bottom six feet of the depth.

Notice that the display works in the opposite direction here. The bottom

is lined up with the yellow zero mark near the 7 O’clock position. The

scale reads from this point up, in the clockwise direction, in one foot incre-

ments. The 6 foot mark is actually six feet off of the bottom.

In figure L, with a range setting of x2, Fish A is near the bottom and

shows both in the full and zoom views. Fish B is more than 6 feet off of

the bottom, so it does not show in the zoom view.

BL, or Bottom Lock, mode works in the same way as the AZ mode. The

only difference is that once the FL-18 finds the bottom, it locks it in posi-

tion on the zoom view. The bottom will change position with depth on
